Examples with SourceVersion javax.lang.model.SourceVersion used on opensource projects

Example 1 with SourceVersion

use of javax.lang.model.SourceVersion in project bazel by bazelbuild.

the class BazelJavaCompiler method newInstance.

private static JavaCompiler newInstance(final JavaCompiler delegate) {
    // We forward most operations to the JavaCompiler implementation in langtools.jar.
    return new JavaCompiler() {

            // so that the user can override them. javac supports this
            // "last option wins" style of option override.
