| # Tests that we don't accidentally add more dependencies. |
| # The test uses jdeps from the embedded JDK to compute the module dependencies |
| # of all class files in A-server.jar. |
| # |
| # If the test fails: |
| # - with a removed dependency: just remove it from the jdeps_modules.golden file |
| # - with an additional dependency: think twice whether to add it to |
| # jdeps_modules.golden since every additional dependency will contribute to |
| # Bazel's binary size |
| # - with an NPE: jdeps crashes on a few class files, add new crashing class |
| # files to jdeps_class_denylist.txt |
| |
