Example 21 with EventBus

use of com.google.common.eventbus.EventBus in project bazel by bazelbuild.

the class SkylarkJavaLiteProtoLibraryTest method testJavaProtosExposeSkylarkProviders.

/**
   * Verify that a java_lite_proto_library exposes Skylark providers for the Java code it generates.
   */
@Test
public void testJavaProtosExposeSkylarkProviders() throws Exception {

// Implicitly check that `update()` above didn't throw an exception. This implicitly checks that
