[python-dm-tree] Bazel build failure with `java.lang.reflect.InaccessibleObjectException`

[HippocampusGirl]

When trying to upgrade python-dm-tree, I get an java.lang.reflect.InaccessibleObjectException. Is there a known workaround?

Just checked, I'm also getting the same error. Most likely an update in bazel causes the current build step to fail for dm-tree. This will be best solved upstream. If you could make an issue upstream and link it here for tracking that would be much appreciated.

Some more digging shows that they have moved over to using cmake instead of bazel as their build system, but have not released a version with cmake. https://github.com/deepmind/tree/issues/16#issuecomment-877072875

Take a look at the python-dm-tree-git package on the AUR. That installed fine for me. I'll go ahead and close this issue once a new version of dm-tree is released upstream without bazel.

Thank you for looking into this :-)
