Is the .runfiles folder necessary for java deploy binaries?

[mvn...@gmail.com]

If I have a java_binary rule, and I build the "name_deploy.jar" target, and I want to deploy this jar, do I need to also copy over the .runfiles folder? I notice there's a "--singlejar" flag in the generated runner script, but looking through the code a bit, it looks like it's disabled with a "<condition> || 1 == 1": https://github.com/bazelbuild/bazel/blob/50681c1b6cca1856f5f7b401ee5c757f22aa2e54/src/main/java/com/google/devtools/build/lib/bazel/rules/java/java_stub_template.txt#L131

So, how can I build a java binary/deploy where .runfiles are not needed to run?

Hi,

This is not necessary if you are not using artifacts provided in the data attribute of your java_* targets. If you don't have a data attribute, you can simply build //my/package:target_deploy.jar that will build a "_deploy.jar" suitable for standalone use.
