Javadoc error: "option --boot-class-path not allowed with target 11"

Question

I have written a fully functional Android app in Intellij, using JDK 11 and Android SDK 28. But I am unable to run JavaDoc on my code, and I can't figure out why or how to fix it! At first, I was getting many errors such as "android.whatever package not found". Simple enough to fix, after googling I found I need to add -bootclasspath pathtomyandroidsdkjarfile to the "extra command line options" section, and that fixes the problem for everyone else. But when I add that line, I get the following error:

error: option --boot-class-path not allowed with target 11

I'm not sure what "target 11" means, but I think I can infer it means the JDK 11. So, I've got no idea where to go from here. Any help anyone can provide would be greatly appreciated!

Answer 1

So after trying a bunch of variations at random, I think I've solved it. It seems like in JDK 10+ the -bootclasspath argument has been deprecated, and has been rolled in together with the -sourcepath argument. So by putting -sourcepath pathtomyandroidsdkjarfile in the "Extra command line options" section, I managed to fix the issue.
