Print runtime classpath for java binary rule in bazel

[Aryeh Hillman]

Is there a way to do this? Something like `println configurations.runtime.resolve()` in gradle.

One way to do this is something like:

bazel cquery //java/app:App --output=starlark --starlark:expr="'\\n'.join([jar.path for jar in providers(target)['JavaRuntimeClasspathProvider'].runtime_classpath.to_list()])"

The output is:

INFO: Analyzed target //java/app:App (46 packages loaded, 741 targets configured).
INFO: Found 1 target...
bazel-out/k8-fastbuild/bin/java/app/App.jar
bazel-out/k8-fastbuild/bin/java/lib/libLib.jar
bazel-out/k8-fastbuild/bin/java/lib2/libLib2.jar
INFO: Elapsed time: 0.814s
INFO: 0 processes.
INFO: Build completed successfully, 0 total actions

for a build like this:

java/app/BUILD:

java_binary(
  name = "App",
  srcs = ["App.java"],
  deps = ["//java/lib:Lib"],
)

java/lib/BUILD:

java_library(
  name = "Lib",
  srcs = ["Lib.java"],
  deps = ["//java/lib2:Lib2"],
  visibility = ["//visibility:public"],
)

java/lib2/BUILD:

java_library(
  name = "Lib2",
  srcs = ["Lib2.java"],
  visibility = ["//visibility:public"],
)
