[1.13] Source code does not match bytecode

[Corey]

I'm having this issue when debugging.  It's happening the same in both of my environments, so I'm assuming it's actually a problem with the source jar.  If I remove the source jar, IntelliJ will decompile the classes and debugging works fine, but obviously I lose documentation and coherent variable names, so that's not ideal.  I haven't see any other mention of this, is it a known issue?

This usually only happens to me if I venture deep into the launch(wrapper) code. How did you set up your workspace?

Import the project twice.

Okay, here's what I ultimately tried:

1. Delete entire gradle cache
2. Freshly clone project
3. Run ./gradlew genIntellijRuns
4. Step 3 again as per https://gist.github.com/mcenderdragon/6c7af2daf6f72b0cadf0c63169a87583 (is that what you mean when you say "Import the project twice"?)
5. Open the project in IntelliJ
6. Add a breakpoint in my code on a call to code in vanilla/forge
7. Run in debug mode, trigger breakpoint, press F7 to step into vanilla/forge code

The same thing happens as in my screenshot above, with the source not matching the bytecode.  The source jar is attached and I can browse through it normally, but it doesn't match in debug mode.

I believe he means you need to refresh the gradle project again. On IntelliJ go to the gradle tab and hit the ? button

Just tried that, but no dice. Also tried with pretty much every Java 8/9/10 version and bytecode version combination possible with identical results each time.
