LGTM 👍

SethTisue · 2019-10-11T17:26:56Z

this will ship in sbt 1.3.3?

eed3si9n · 2019-10-11T17:48:17Z

Yes.

@retronym I tried compiling kafka with Gradle, Scala 2.12.11, Java 11 and Zinc 1.3.5 (which has this fix) and I still get:

This stack trace suggests that I'm still using an old version of Zinc via Gradle 6.3 -- notice that it stall calls AnnotationInfo.isStatic rather than the StubSymbol aware version added in this PR.

What version of Gradle (or Gradle Scala Plugin, if that is separately upgradable) are you testing with?

retronym · 2020-04-21T03:26:37Z

Oh, I see you've been busy: gradle/gradle@3dfd2b1

ijuma · 2020-04-21T03:50:19Z

Thanks for checking this! I thought I was overriding the zinc version via:

https://github.com/apache/kafka/blob/trunk/build.gradle#L428
https://github.com/apache/kafka/blob/trunk/gradle/dependencies.gradle#L118

As you found, I also submitted the Zinc upgrade to the Gradle project. That should be part of Gradle 6.4. I'll try Gradle 6.4 RC1 to check if it fixes the issue.

retronym · 2020-04-21T04:01:06Z

Hmmm, it does look like the right version of Zinc is in use already.

Oh:

Needs a backport and a new Zinc release, I guess.

retronym · 2020-04-21T04:06:50Z

Hmmm, it was already backported in #705.

ijuma · 2020-04-21T04:12:01Z

Good news, Gradle 6.4-RC1 fixes the issue! No idea why though.

Gradle 6.3:

I suspect there is a bug in Gradle's resolution and/or dynamic compilation of compiler-interface.jar, perhaps only when you exceed the maximum supported version of Zinc?

ijuma · 2020-04-21T04:27:13Z

Possibly. :) In any case, it looks like this should work out of the box soon, which is great. Thanks for the help!

DownloadingScalaToolChain in Gradle code hard codes references to DEFAULT_ZINC_VERSION. It's likely that this is ignoring the per-project configuration.

ijuma · 2020-04-21T12:39:38Z

Good find! Are you planning to submit the bug upstream?

retronym · 2020-04-22T03:24:01Z

Good idea: gradle/gradle#12869

ijuma · 2020-04-22T03:38:33Z

Thanks!

In 6f32b62, I made sure the compiler could survive parsing a Java classfile referring to annotations missing from the classpath, but we could still run into trouble when a Scala unpickled class does the same. Tweaking the Tasty unpickler to drop missing annotations would require always forcing the symbols of all annotations which I would rather avoid doing. Instead, we adopt the same solution as Scala 2 did in sbt/zinc#701 and special-case the single place where we force annotations of inherited members to ignore missing annotations.
