Opened issue on YouTrack here but no response for almost a month.
I have a multi module ear project where the java backend portion is not being recognized as inside the project root. This is because of maven not having access to a target folder to create an application.xml. Here's a copy of the IntelliJ log.
It seems to hit a NoClassDefFoundError on DefaultFileSystemHolder and HttpWagon. I can still build my project fine because I set npm, jdk, maven, maven importer, etc paths inside wsl2 instead of on C:/... But in the Maven tool window all the project modules are red underlined and the plugins are not shown. When hovering here it gives one of either noclassdeffounderrors, not always the same (httpwagon or defaultfilesystemholder).
My TS/React module seems fine with code completion etc, but the java backend and api modules are not being recognized at all. When hovering over one of the file icons with the red J it says "Java file outside of source root".
Please, if there's any other information/logs/anything I can provide please let me know.
