Provides access to the Android SDK configuration.

Miscellaneous machinery around traversing & querying the build hierarchy, that should not be needed by normal users of Mill

Aggregation of mandatoryIvyDeps and ivyDeps. In most cases, instead of overriding this Target you want to override ivyDeps instead.

All individual source files fed into the Java compiler

The folders containing all source files fed into the compiler

Adds --proto-format option to AAPT commands.

Optimizes the APK using the zipalign tool for better performance.

For more details on the zipalign tool, refer to: zipalign Documentation

Signs the APK using a keystore to generate a final, distributable APK.

The signing step is mandatory to distribute Android applications. It adds a cryptographic signature to the APK, verifying its authenticity. This method uses the apksigner tool along with a keystore file to sign the APK.

If no keystore is available, a new one is generated using the keytool utility.

For more details on the apksigner tool, refer to: apksigner Documentation

Signs the AAB using the specified keystore.

Creates a zip with compiled resources and DEX files for the app bundle.

Converts the generated JAR file into a DEX file using the d8 tool.

Packages the compiled Java .class files into a JAR file using the D8 tool.

The D8 compiler is used here to package and optimize the Java bytecode into a format suitable for Android (DEX). D8 converts the Java .class files into a jar file which is suitable for DEX (Dalvik Executable) format and is required for Android runtime.

For more details on the d8 tool, refer to: d8 Documentation

Generates a new keystore file if it does not exist.

A keystore is required to sign the APK for distribution. This method checks if a keystore exists, and if not, generates a new one using the keytool utility. The keystore holds the cryptographic keys used to sign the APK.

For more details on the keytool utility, refer to: keytool Documentation

Provides Path to an XML file containing configuration and metadata about your android application.

Default alias in the keystore ("androidKey"). Users can customize this value.

Default name of the keystore file ("keyStore.jks"). Users can customize this value.

Default password for the key ("android"). Users can customize this value.

Default path to the keystore file, derived from androidReleaseKeyName(). Users can customize the keystore file name to change this path.

Default password for the keystore ("android"). Users can customize this value.

Compiles Android resources and generates R.java and res.apk.

Generates the command-line arguments required for Android app signing.

Uses the release keystore path if available; otherwise, defaults to a standard keystore path. Includes arguments for the keystore path, key alias, and passwords.

Extracts JAR files and resources from AAR dependencies.

Packages DEX files and Android resources into an unsigned APK.

Builds an unsigned Android App Bundle (AAB) from the bundle zip.

The exact id of the artifact to be published. You probably don't want to override this. If you want to customize the name of the artifact, override artifactName instead. If you want to customize the scala version in the artifact id, see ScalaModule.artifactScalaVersion

Override this to change the published artifact id. For example, by default a scala module foo.baz might be published as foo-baz_2.12 and a java module would be foo-baz. Setting this to baz would result in a scala artifact baz_2.12 or a java artifact baz.

The suffix appended to the artifact IDs during publishing

Adds "aar" to the handled artifact types.

An executable uber-jar/assembly containing all the resources and compiled classfiles from this module and all it's upstream modules and dependencies

Configuration for the assembly task: how files and file-conflicts are managed when combining multiple jar files into one big assembly jar.

Bind a dependency (Dep) to the actual module context (e.g. the scala version and the platform suffix)

Use to fill most fields of BuildTarget.

Use to populate the BuildTarget.{dataKind,data} fields.

Mill specific implementations: - JvmBuildTarget - ScalaBuildTarget

The path to the compiled classes by compile without forcing to actually run the compilation. This is safe in an BSP context, as the compilation done later will use the exact same compilation settings, so we can safely use the same path.

Keep in sync with compile

Same as compileClasspath, but does not trigger compilation targets, if possible.

Keep in sync with compileClasspath

Same as localClasspath, but with all dependencies on compile replaced by their non-compiling bspCompileClassesPath variants.

Keep in sync with localClasspath

Same as localRunClasspath but for use in BSP server.

Keep in sync with localRunClasspath

Same as transitiveCompileClasspath, but with all dependencies on compile replaced by their non-compiling bspCompileClassesPath variants.

Keep in sync with transitiveCompileClasspath

Same as transitiveLocalClasspath, but with all dependencies on compile replaced by their non-compiling bspCompileClassesPath variants.

Keep in sync with transitiveLocalClasspath

Compiles the current module to generate compiled classfiles/bytecode.

When you override this, you probably also want/need to override bspCompileClassesPath, as that needs to point to the same compilation output path.

Keep in sync with bspCompileClassesPath

Replaces AAR files in classpath with their extracted JARs.

Same as ivyDeps, but only present at compile time. Useful for e.g. macro-related dependencies like scala-reflect that doesn't need to be present at runtime

The compile-only direct dependencies of this module. These are *not* transitive, and only take effect in the module that they are declared in.

Same as compileModuleDeps but checked to not contain cycles.

The folders where the compile time resource files for this module live. If your resources files do not necessarily need to be seen by the compiler, you should use resources instead.

Customize the coursier file cache.

This is rarely needed to be changed, but sometimes e.g. you want to load a coursier plugin. Doing so requires adding to coursier's classpath. To do this you could use the following:

override def coursierCacheCustomizer = Task.Anon {
   Some( (fc: coursier.cache.FileCache[Task]) =>
     fc.withClassLoaders(Seq(classOf[coursier.cache.protocol.S3Handler].getClassLoader))
   )
}

The name of the default command, which will be automatically executed if the module name is provided at the Mill command line.

The documentation jar, containing all the Javadoc/Scaladoc HTML files, for publishing to Maven Central

Control whether docJar-target should use a file to pass command line arguments to the javadoc tool. Defaults to true on Windows. Beware: Using an args-file is probably not supported for very old javadoc versions.

Extra directories to be copied into the documentation.

Typically, includes static files such as html and markdown, but depends on the doc tool that is actually used.

Directories to be processed by the API documentation tool.

Typically, includes the source files to generate documentation from.

Any command-line parameters you want to pass to the forked JVM under run, test or repl

Any environment variables you want to pass to the forked JVM under run, test or repl

Combines standard Java source directories with additional sources generated by the Android resource generation step.

Contribute components to idea config files.

Contribute facets to the Java module configuration.

Any ivy dependencies you want to add to this Module, in the format ivy"org::name:version" for Scala dependencies or ivy"org:name:version" for Java dependencies

Command to print the transitive dependency tree to STDOUT.

A jar containing only this module's resources and compiled classfiles, without those from upstream modules and dependencies

Options to pass to the java compiler

Additional options to be used by the javadoc tool. You should not set the -d setting for specifying the target directory, as that is done in the docJar target.

Builds a command-line "launcher" file that can be used to run this module's code, without the Mill process. Useful for deployment & other places where you do not want a build tool running

The *output* classfiles/resources from this module, used for execution, excluding upstream modules and third-party dependencies, but including unmanaged dependencies.

This is build from localCompileClasspath and localRunClasspath as the parts available "before compilation" and "after compilation".

Keep in sync with bspLocalClasspath

The *input* classfiles/resources from this module, used during compilation, excluding upstream modules and third-party dependencies

The part of the localClasspath which is available "after compilation".

Keep in sync with bspLocalRunClasspath

Allows you to specify an explicit main class to use for the run command. If none is specified, the classpath is searched for an appropriate main class to use if one exists

Mandatory ivy dependencies that are typically always required and shouldn't be removed by overriding ivyDeps, e.g. the scala-library in the ScalaModule.

Additional options for the java compiler derived from other module settings.

Creates a manifest representation which can be modified or replaced The default implementation just adds the Manifest-Version, Main-Class and Created-By attributes

Map dependencies before resolving them. Override this to customize the set of dependencies.

The direct dependencies of this module. This is meant to be overridden to add dependencies. To read the value, you should use moduleDepsChecked instead, which uses a cached result which is also checked to be free of cycle.

Same as moduleDeps but checked to not contain cycles. Prefer this over using moduleDeps directly.

What platform suffix to use for publishing, e.g. _sjs for Scala.js projects

What shell script to use to launch the executable generated by assembly. Defaults to a generic "universal" launcher that should work for Windows, OS-X and Linux

Task that print the transitive dependency tree to STDOUT. NOTE: that when whatDependsOn is used with inverse it will just be ignored since when using whatDependsOn the tree _must_ be inversed to work, so this will always be set as true.

The direct and indirect dependencies of this module

The direct and indirect runtime module dependencies of this module

The repositories used to resolved dependencies with resolveDeps().

Customize the coursier resolution process. This is rarely needed to changed, as the default try to provide a highly reproducible resolution process. But sometime, you need more control, e.g. you want to add some OS or JDK specific resolution properties which are sometimes used by Maven and therefore found in dependency artifact metadata. For example, the JavaFX artifacts are known to use OS specific properties. To fix resolution for JavaFX, you could override this task like the following:

override def resolutionCustomizer = Task.Anon {
  Some( (r: coursier.core.Resolution) =>
    r.withOsInfo(coursier.core.Activation.Os.fromProperties(sys.props.toMap))
  )
}

Resolution parameters, allowing to customize resolution internals

This rarely needs to be changed. This allows to disable the new way coursier handles BOMs since coursier 2.1.17 (used in Mill since 0.12.3) for example, with:

def resolutionParams = super.resolutionParams()
  .withEnableDependencyOverrides(Some(false))

Note that versions forced with Dep#forceVersion() take over forced versions manually set in resolutionParams. The former should be favored to force versions in dependency resolution.

The Scala version set via ScalaModule#scalaVersion also takes over any Scala version provided via ResolutionParams#scalaVersionOpt.

Task that resolves the given dependencies using the repositories defined with repositoriesTask.

Resolved dependencies based on transitiveIvyDeps and transitiveCompileIvyDeps.

Combines module resources with those unpacked from AARs.

Runs this module's code in a subprocess and waits for it to finish

Runs this module's code in a background process, until it dies or runBackground is used again. This lets you continue using Mill while the process is running in the background: editing files, compiling, and only re-starting the background process when you're ready.

You can also use -w foo.runBackground to make Mill watch for changes and automatically recompile your code & restart the background process when ready. This is useful when working on long-running server processes that would otherwise run forever

If true, stdout and stderr of the process executed by runBackground or runMainBackground is sent to mill's stdout/stderr (which usually flow to the console).

If false, output will be directed to files stdout.log and stderr.log in runBackground.dest (or runMainBackground.dest)

All classfiles and resources from upstream modules and dependencies necessary to run this module's code after compilation

Runs this module's code in a subprocess and waits for it to finish

Additional dependencies, only present at runtime. Useful for e.g. selecting different versions of a dependency to use at runtime after your code has already been compiled.

Runs this module's code in-process within an isolated classloader. This is faster than run, but in exchange you have less isolation between runs since the code can dirty the parent Mill process and potentially leave it in a bad state.

Same as run, but lets you specify a main class to run

Same as runBackground, but lets you specify a main class to run

Same as runLocal, but lets you specify a main class to run

The runtime-only direct dependencies of this module. These *are* transitive, and so get propagated to downstream modules automatically

Same as moduleDeps but checked to not contain cycles. Prefer this over using moduleDeps directly.

Control whether run*-targets should use an args file to pass command line args, if possible.

Scalac options to activate the compiler plugins.

Show the module dependencies.

Skip Idea project file generation.

The transitive version of compileClasspath

The compile-only transitive ivy dependencies of this module and all it's upstream compile-only modules.

The transitive ivy dependencies of this module and all it's upstream modules. This is calculated from ivyDeps, mandatoryIvyDeps and recursively from moduleDeps.

The transitive version of localClasspath

All direct and indirect module dependencies of this module, including compile-only dependencies: basically the modules whose classpath are needed at compile-time.

Note that compileModuleDeps are defined to be non-transitive, so we only look at the direct compileModuleDeps when assembling this list

Like recursiveModuleDeps but also include the module itself, basically the modules whose classpath are needed at runtime

All direct and indirect module dependencies of this module, including compile-only dependencies: basically the modules whose classpath are needed at runtime.

Note that runModuleDeps are defined to be transitive

The transitive run ivy dependencies of this module and all it's upstream modules. This is calculated from runIvyDeps, mandatoryIvyDeps and recursively from moduleDeps.

Like recursiveModuleDeps but also include the module itself, basically the modules whose classpath are needed at runtime

Adds the Android SDK JAR file to the classpath during the compilation process.

Build the assembly for upstream dependencies separate from the current classpath

This should allow much faster assembly creation in the common case where upstream dependencies do not change

All upstream classfiles and resources necessary to build and executable assembly, but without this module's contribution

The upstream compilation output of all this module's upstream modules

Files extensions that need to be managed by Zinc together with class files. This means, if zinc needs to remove a class file, it will also remove files which match the class file basename and a listed file extension.

If true, we always show problems (errors, warnings, infos) found in all source files, even when they have not changed since the previous incremental compilation. When false, we report only problems for files which we re-compiled.

Build the assembly for upstream dependencies separate from the current classpath

This should allow much faster assembly creation in the common case where upstream dependencies do not change

This implementation is deprecated because of it's return value. Please use upstreamAssembly2 instead.
