Need a solution to replace Java -sourcepath in Bazel java support (use-case: Groovy stubs)

This was reported while testing 0.4.5rc1 by a user that was not able to update to 0.4.4 due to the java bug.

$ ls -R
.:
bazel-bin  bazel-genfiles  bazel-out  bazel-test  bazel-testlogs  g  WORKSPACE

./g:
A.java  B.java  BUILD
[dmarting@trantor] /tmp/test$ cat WORKSPACE 
[dmarting@trantor] /tmp/test$ cat g/A.java
package g;
public class A {
   public A() {
      new B();
   }
}
[dmarting@trantor] /tmp/test$ cat g/B.java
package g;
public class B {
   public B() {
   }
}
[dmarting@trantor] /tmp/test$ cat g/BUILD 
genrule(
  name = "stub",
  srcs = ["B.java"],
  outs = ["B.jar"],
  cmd = "zip $@ $(SRCS)",
)

java_library(
  name = "test",
  srcs = ["A.java"],
  javacopts = ["-sourcepath $(GENDIR)/$(location :stub)", "-implicit:none"],
  deps = [":stub"]
)

nope we have the temporary solution in the current RC (supporting -sourcepath in javacopts) so we can take the time to have a proper API for this use case.

Damien helped me figure it out. It was because my files were under java/com/google/somenameand the expected location of B.jar was com/google/somename/B.jar. Thanks!
