Fail to generate BUILD files for gitea

[qzmfranklin]

What version of rules_go are you using?

0.18.3

What version of gazelle are you using?

44ce230

What version of Bazel are you using?

0.24.1

Does this issue reproduce with the latest releases of all the above?

YES

What operating system and processor architecture are you using?

Ubuntu 18.04.1
Intel i7-8770k

Any other potentially useful information about your toolchain?

Nope

What did you do?

Put the following in WORKSPACE:

    go_repository(
        name = 'com_github_go_gitea_gitea',
        strip_prefix = r'''gitea''',
        urls = ['https://github.com/go-gitea/gitea/archive/v1.8.0.tar.gz'],
        importpath = r'''github.com/go-gitea/gitea''',
    )

(and a lot of other dependencies for building gitea, omitted here)

Then try building it with

bazel build @com_github_go_gitea_gitea//cmd

It yields the following errors:

INFO: Repository 'com_github_go_gitea_gitea' used the following cache hits instead of downloading the corresponding file.

If the definition of 'com_github_go_gitea_gitea' was updated, verify that the hashes were also updated.

Admittedly, the file names that caused the errors are non-ascii. But somehow I still want to build gitea with Bazel. Help is appreciated!

I think the root cause of this is bazelbuild/bazel#7055. I don't think that fix is in Bazel 0.24.1, but it might be in 0.25.0. Does upgrading to 0.25.0 solve your problem? If not, does Bazel built at master work?

@jayconrod
Thanks for the info!

I tried 0.25. But it fails the build in too many other places. I cannot even reach the point of failure mentioned in this issue easily.

Seeing how much 0.25 broke, I believe it will take some time for my team will move to 0.25. Will get back to this issue when we get there.

Thanks again. Will keep an eye out for this.
