rules_java_extensions

Bazel macros to extend java functionality. Hopefully will be converting them to actual rules in the future.

jar_repack

jar_repack allows us to repackage an existing jar to use a new class name (similar to maven shading).

Example Usage:

load("@io_bazel_rules_java_extensions//java_extensions:jar_repack.bzl", "jar_repack")
jar_repack(
    name = "jarjar-new",
    old_class_name = "org.pantsbuild.**",
    new_class_name = "com.example.test.@1",
    src_jar = "@org_pantsbuild_jarjar//jar"
)

junit_test

This macro allows JUnit4 tests to be run.

Original form taken from bazelbuild/bazel#1017 (comment)

• Generates a Junit4 TestSuite
• Assumes srcs are all .java test files
• Assumes junit4 is already added to deps

Example Usage:

load("@io_bazel_rules_java_extensions//java_extensions:junit_test.bzl", "junit_test")
junit_test(
    name = "tests",
    deps = [
        ":libs",
        "@org_apache_lucene_lucene_core//jar",
        "@commons_logging_commons_logging//jar",
        "@org_mockito_mockito_all//jar",
        "@org_powermock_powermock_api_mockito//jar",
        "@org_powermock_powermock_api_support//jar",
        "@org_powermock_powermock_core//jar",
        "@org_powermock_powermock_reflect//jar",
        "@org_javassist_javassist//jar",
        "@org_powermock_powermock_module_junit4//jar",
        "@org_powermock_powermock_module_junit4_common//jar",
        "@org_skyscreamer_jsonassert//jar",
        "@junit_junit//jar",
    ],
    srcs = glob(
        [
            "src/test/**/*.java"
        ]
    )
)
