- // java_genrule is a genrule that can depend on other java_* objects.
- //
- // By default a java_genrule has a single variant that will run against the device variant of its dependencies and
- // produce an output that can be used as an input to a device java rule.
- //
- // Specifying `host_supported: true` will produce two variants, one that uses device dependencies and one that uses
- // host dependencies. Each variant will run the command.
- //
- // Use a java_genrule instead of a genrule when it needs to depend on or be depended on by other java modules, unless
- // the dependency is for a generated source file.
- //
- // Examples:
- //
- // Use a java_genrule to package generated java resources:
- //
- // java_genrule {
- // name: "generated_resources",
- // tools: [
- // "generator",
- // "soong_zip",
- // ],
- // srcs: ["generator_inputs/**/*"],
- // out: ["generated_android_icu4j_resources.jar"],
- // cmd: "$(location generator) $(in) -o $(genDir) " +
