    Iterable<? extends JavaFileObject> compilationUnits = fileManager
            .getJavaFileObjectsFromStrings(Arrays.asList("YourFile.java"));
    Iterable<String> options = Arrays.asList("-d", "classes", "-sourcepath", "src");
    JavaCompiler.CompilationTask task = compiler.getTask(null, fileManager, diagnostics, options, null,
