// 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 dependencie sand 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) " +
// "&& $(location soong_zip) -o $(out) -C $(genDir)/res -D $(genDir)/res",
// }
//
// java_library {
// name: "lib_with_generated_resources",
// srcs: ["src/**/*.java"],
// static_libs: ["generated_resources"],
