0.27.0-RC1 artifacts require Java 11

I get the above error whenever I attempt to use µTest 0.7.5 from Dotty 0.27.0-RC1 (the 2.12 and 2.13 artifacts do not exhibit this issue).

@lihaoyi, I think this is the same problem seen here: https://github.com/lihaoyi/geny/pull/17

[darkfrog26]

@lihaoyi I believe this is the lynchpin keeping geny from releasing, that is keeping upickle from releasing, that is keeping profig from releasing, that is keeping scribe from releasing. I would be happy to take a look and see if I can figure out why this is happening, but I'm not at all familiar with Mill.

The problem arises because utest & sourcecode for Scala 3 were published for Java 11 by mistake. The solution is either to bump the version of these two libs and release them for Java 8, or wait a couple of weeks until Scala 3 RC1 is here, and release these libs for RC1 under Java 8.

@anatoliykmetyuk can anyone but @lihaoyi do another release?

[anatoliykmetyuk]

I can publish a release once @lihaoyi advises on how we should proceed with it.

[lihaoyi]

Feel free to bump a version and republish everything

@anatoliykmetyuk any idea when you'll be able to get to this?

[anatoliykmetyuk]

I'm on vacation for the next two weeks, so I can look into it at the beginning of February. But then, we would probably have another release of Dotty, so, if nobody tags the new version by that time, we won't need to tag a new version.

[darkfrog26]

Is there anything I can do to expedite this? I can submit a PR if that would help move this along?

[lolgab]

Do you still need this? The latest version was released for Scala 3.0.0-RC1 which is not source-compatible with 0.27.0-RC1.

[darkfrog26]

I don't.
