Question

JavaCompiler – How to pass -X options programmatically to the JavaCompiler class?

Answer 1

The JavaCompiler page you linked to has some nice examples. They invoke the compiler with the following line of code:

compiler.getTask(null, fileManager, null, null, null, compilationUnits1).call();

The fourth argument to the getTask method is a list of option strings (really Iterable<String> but a list will be sufficient). So you can do:

compiler.getTask(null, fileManager, null,
    Arrays.asList("-Xlint:all"),
    null, compilationUnits1).call();
