Trying to figure out why the build is breaking.

[netdpb]

Can't break it locally. Trying to add --stacktrace here.

[netdpb]

I give up.

@netdpb The CI failure looks like something goes wrong with annotation-tools.
Maybe these two help: jspecify/checker-framework#40 and jspecify/checker-framework#41
It works for me locally :-)

[netdpb]

It works for me locally too, even without those.

Yes, it's an issue with annotation-tools, which also uses an old Gradle. I think we should give up on this until you've finished deforking. Then we will be able to depend on a released version of annotation-tools (and eisop), right?

[wmdietl]

eisop doesn't depend on annotation-tools. Merging the two checker-framework PRs should unblock this PR and wouldn't make deforking harder.

Oh cool! I commented on some Gradle and shell bits of the first one.
