hey folks, the HEAD is broken for
rules_kotlin
for many folks. it’d be great if we could unblock it so teams can upgrade to kotlin 1.5 https://github.com/bazelbuild/rules_kotlin

The last release cut a few weeks ago should work with Kotlin 1.5.21 afaik

We tried it but it doesn't work for us :( There are multiple folks who aren't able to use it because of the cyclic dependency error in bazel

Did you try the release archive? What's the error you're facing?
p

Pratik Tandel

This wasn't reported by me but we're seeing a similar error: https://github.com/bazelbuild/rules_kotlin/issues/602

I've got a very similar declaration in my repo and no problem with it - the only obvious difference is that I manually specify a
compiler_release
in the
kotlin_repositories
call, and a toolchain
Ha no sorry I'm not on the release... My bad
Let me try to update the the beta 4 see how that goes
Welp the beta 4 release archive has the same checksum as the one I had built locally so no difference here - it works fine here 😕
I'm wondering if passing a specific compiler release would work for you:
kotlin_repositories(
    compiler_release = kotlinc_version(
        release = kotlin_compiler.version,
        sha256 = kotlin_compiler.sha,
    ),
)
For reference, the version and checksum I have for the compiler:
version = "1.5.21",
    sha = "f3313afdd6abf1b8c75c6292f4e41f2dbafefc8f6c72762c7ba9b3daeef5da59",

Ok thanks. Will take a look at that tomorrow. A stable, workable new release would be great. We'd like to use ktlint and some other new changes that were shipped
m

That's been in the works for a bit afaik, but the compiler being an ever moving target, and the resources to work on this being quite thin, it's been consistently delayed by one more thing, from what I can see in the issues tracker...

i tried it but it requires a newer rules_kotlin version than the one we’re on. we had some issues with ECR records but i believe that’s fixed now (or there’s a workaround)
Still seeing this error:
ERROR: Failed to load Starlark extension '@rkt_1_4//jvm:opts.bzl'.
Cycle in the workspace file detected. This indicates that a repository is used prior to being defined.
The following chain of repository dependencies lead to the missing definition.
 - @rkt_1_4
This could either mean you have to add the '@rkt_1_4' repository with a statement like `http_archive` in your WORKSPACE file (note that transitive dependencies are not added automatically), or move an existing definition earlier in your WORKSPACE file.
