Let say that you want to build for Java 8 and errorprone checks off but keep the tools directory provided with Bazel in the package path, you could do that by having the following rc file:
build --javacopt="-extra_checks:off" build --javacopt="-source 8" build --javacopt="-target 8"
However, the file would becomes quickly overloaded, especially if you take all languages and options into account. Instead, you can tweak the java_toolchain rule that specifies the various options for the java compiler. So in a BUILD file:
java_toolchain( name = "my_toolchain", encoding = "UTF-8", source_version = "8", target_version = "8", misc = [ "-extra_checks:on", ], )
And to keep it out of the tools directory (or you need to copy the rest of the package), you can redirect the default one in a bazelrc:
In the future, toolchain rules should be the configuration points for all
the languages but it is a long road. We also want to make it easier to
rebind the toolchain using the
bind rule in the WORKSPACE file.
