Examples with DiagnosticListener javax.tools.DiagnosticListener used on opensource projects

Example 1 with DiagnosticListener

use of javax.tools.DiagnosticListener in project lombok by rzwitserloot.

the class TestClassFileMetaData method compile.

static byte[] compile(File file) {
    try {
        JavaCompiler compiler = ToolProvider.getSystemJavaCompiler();
        File tempDir = getTempDir();
        tempDir.mkdirs();

            @Override
            public void report(Diagnostic<? extends JavaFileObject> diagnostic) {
                compilerErrors.append(diagnostic.toString()).append("\n");
            }
        };
        CompilationTask task = compiler.getTask(captureWarnings, null, diagnostics, options, null, Collections.singleton(new ContentBasedJavaFileObject(file.getPath(), readFileAsString(file))));

Example 2 with DiagnosticListener

use of javax.tools.DiagnosticListener in project bazel by bazelbuild.

the class BazelJavaCompiler method newInstance.

private static JavaCompiler newInstance(final JavaCompiler delegate) {

            // We prepend bazel's default javacopts to user javacopts,
            // so that the user can override them. javac supports this
