Commit Messages
We want to keep history, but for that to actually be useful we have
some rules on how to format our commit messages (relevant xkcd).
Please stick to these guidelines for commit messages:
- Separate subject from body with a blank line
- When fixing an issue, start your commit message with
Fix #<ISSUE-NBR>:- Limit the subject line to 72 characters
- Capitalize the subject line
- Do not end the subject line with a period
- Use the imperative mood in the subject line ("Add" instead of "Added")
- Wrap the body at 80 characters
- Use the body to explain what and why vs. how

Well, this doesn't work, because when Zinc compiles the compiler bridge, it assumes it's entirely written in Scala. See So no source ends up being compiled, the jar/class directly is empty, and then of course Zinc cannot find the classes it's looking for. This would require changes in Zinc to move forward. |

No, the Javadoc guide does not use the closing </p>s.
I feared that. I'll look into it. |

Only the files in the Compile configuration are translated. Tests are kept in Scala.
Normally, the source of the sbt bridge is fetched from scalaCompilerBridgeSource, compiled, then cached by sbt. Unfortunately the logic in sbt to do this does not take .java source files into account, so the previous commit broke our bridge. Thankfully, it turns out that I have amazing foresight ;). In sbt/sbt#4332 I added scalaCompilerBridgeBinaryJar to sbt, which bypasses the whole bridge compilation and caching logic which is not needed when the bridge is Java-only and thus binary-compatible across Scala releases. So just using this setting is enough to make everything work!
Not needed now that the project is Java-only.

These caches are only used with scalaCompilerBridgeSource, so we don't need them now that we switched to scalaCompilerBridgeBinaryJar

You shouldn't have to, we publish binary artefacts for the compiler bridge which are directly usable. In sbt this is handled by https://github.com/sbt/sbt/blob/develop/zinc-lm-integration/src/main/scala/sbt/internal/inc/ZincLmUtil.scala (which is called from https://github.com/sbt/sbt/blob/2a26e8186894dc0af46cd142306727b1acd722f8/main/src/main/scala/sbt/Defaults.scala#L808-L814) |

By the way, if you're looking into this to get scala 3 support in gradle, check out gradle/gradle#18001 |
I am! My attempt is at [gradle/gradle#18003] ;) |
