Examples with JavacTask com.sun.source.util.JavacTask used on opensource projects

Example 1 with JavacTask

use of com.sun.source.util.JavacTask in project buck by facebook.

the class TracingTaskListener method setupTracing.

public static void setupTracing(JavaCompiler.CompilationTask task, JavacPhaseTracer tracing, Object next) {
    if (!(task instanceof JavacTask)) {
        return;
    }
    final JavacTask javacTask = (JavacTask) task;
    // The main part of Buck doesn't have access to `TaskListener`, since that's defined in the
    // compiler jar. So we had to pass it as an object and downcast.
    final TaskListener nextListener = (TaskListener) next;
    javacTask.setTaskListener(new TracingTaskListener(tracing, nextListener));
}
