I'm not able to limit the module.

You usually have a space between `--limit-modules` and its arguments, not a `,` — tgdavies, Nov 28 '22 at 05:40

The list for --limit-modules is a separate argument.

Mixing compilerArgument and compilerArgs does not work properly, compilerArgs is overring the compilerArgument entries which are being ignored (you can tell this because --warn:none and --err:none are not actually valid).

So use:

 <compilerArgs>
   <arg>-warn:none</arg>
   <arg>-err:none</arg>
   <arg>-warn:+discouraged,forbidden</arg>
   <arg>--limit-modules</arg>
   <arg>java.base,java.compiler ... rest of modules ...</arg>
</compilerArgs>
