Travis-CI PR validation is failing with "can't read buildcharacter.properties"

[SethTisue]

The symptom is that both "build" jobs succeed, but then all the "test" jobs fail with

$ STARR=$(sed -n 's/^maven\.version\.number=//p' buildcharacter.properties) && echo $STARR
sed: can't read buildcharacter.properties: No such file or directory

you can trace it back to the build job, where at the end it says:

store build cache
...
failed to upload cache

one hopes this is a transient problem at Travis-CI's end? since we didn't change anything

It's actually the workspace files, which aren't just an optimisation like the cache is:

maybe this is fixed now? https://github.com/scala/scala/pull/9477 passed

What an annoying problem, but it builds character. Which is why it's called buildcharacter.properties.

Looks like a bug in Travis-CI: https://travis-ci.community/t/repeatable-failed-to-upload-workspace-error/11108
