Examples with PathClassLoader com.google.devtools.j2objc.util.PathClassLoader used on opensource projects

Example 1 with PathClassLoader

use of com.google.devtools.j2objc.util.PathClassLoader in project j2objc by google.

the class AnnotationPreProcessor method hasAnnotationProcessors.

/**
   * Check whether any javax.annotation.processing.Processor services are defined on
   * the declared classpath. This is checked here to avoid batch compiling sources
   * in case any might have annotations that should be processed.
   */
private boolean hasAnnotationProcessors() {
    PathClassLoader loader = new PathClassLoader(options.fileUtil().getClassPathEntries());
    loader.addPaths(options.getProcessorPathEntries());
    ServiceLoader<Processor> serviceLoader = ServiceLoader.load(Processor.class, loader);
    Iterator<Processor> iterator = serviceLoader.iterator();
    return iterator.hasNext();
}

Example 2 with PathClassLoader

use of com.google.devtools.j2objc.util.PathClassLoader in project j2objc by google.

the class JavacParser method processAnnotations.

@Override

    final List<ProcessingContext> generatedInputs = Lists.newArrayList();
    PathClassLoader loader = new PathClassLoader(options.fileUtil().getClassPathEntries());

            inputFiles.add(new File(input.getFile().getAbsolutePath()));
        }
        try {
            JavacEnvironment env = createEnvironment(inputFiles, null, true);
            env.task().parse();
            env.task().analyze();
            processDiagnostics(env.diagnostics());
            // The source output directory is created and set in createEnvironment().
            File sourceOutputDirectory = env.fileManager().getLocation(StandardLocation.SOURCE_OUTPUT).iterator().next();
            collectGeneratedInputs(sourceOutputDirectory, "", generatedInputs);
            return new JavacProcessingResult(generatedInputs, sourceOutputDirectory);
        } catch (IOException e) {
            ErrorUtil.fatalError(e, "javac file manager error");
        }
