Problem
java_library
depending on anotherjava_library
Change overview
jar_path
field injava_library
template, mutually exclusive withsources
. If set, the build rule skips the javac and jar actions and instead just copies the JAR fromjar_path
into the build directory.write_build_config.py
script, which outputs a JSON file ("build config") describing each build target.javac_runner.py
to read a build config JSON and modify classpath accordingly.Testing
java_prebuilt
rules, I createdgenerate_jars_for_test.py
. This script needs to be run before other Java things are built, or GN won't be able to find thejar_path
.android.py
, go back to copying JARs tolibs/
. The app only needsCHIPController.jar
andSetupPayload.jar
, but thechipSdkBuildDir
approach would copy all JARs.
