Example 1 with PrintingEventHandler

use of com.google.devtools.build.lib.events.PrintingEventHandler in project bazel by bazelbuild.

the class ParallelBuilderTest method testProgressReporting.

@Test

Example 2 with PrintingEventHandler

    // reporter, i.e., this is a one-shot change. Maybe we should store the external reporter here?
