I'm developing a compiler plugin for Javac. My codebase uses preview features, so I need to run using the flag --enable-preview. I can compile my code perfectly using maven, but when I try to do the same using IntelliJ this error is thrown:
java: An exception has occurred in the compiler (17). Please file a bug against the Java compiler via the Java bug reporting page (http://bugreport.java.com) after checking the Bug Database (http://bugs.java.com) for duplicates. Include your program, the following diagnostic, and the parameters passed to the Java compiler in your report. Thank you.
java: java.lang.UnsupportedClassVersionError: Preview features are not enabled for it/auties/optional/tree/Maker (class file version 61.65535). Try running with '--enable-preview'

As already mentioned, I'm already running using --enable-preview, but Javac doesn't seem to pick this option for the compiler plugin.
