Compile error with rules_jvm_external

[peakschris]

I am trying this toolchain in our bazel 7.2.1 project. We use modules and rules_jvm_external. I fixed one small issue with windows, and then am seeing this problem:

Is there a way to resolve this? or a way to use JDT conditionally only for our own code?

Do you still recommend use of JDT in bazel7/modules world?

I can contribute fixes if I can get some guidance as to where the issue is.

I haven't tried with this project. But it looks like the list of dependencies is not correct. Is there a PR/branch to play with?

Hi there, thanks for the reply,

Here is a reproducer: https://github.com/peakschris/jdt-compiler-issue

It references a fork of this repo with one small fix for windows: https://github.com/salesforce/bazel-jdt-java-toolchain/pull/29
