Crash when Konan classes aren’t downloaded yet

[swankjesse]

I’m seeing this in CI for Zipline, and can reproduce locally by deleting my local Konan directory.

$ rm -rf ~/.konan/kotlin-native-prebuilt-*
$ ./gradlew build --stacktrace

FAILURE: Build failed with an exception.

* Where:
Build file '/Users/jwilson/Projects/zipline/zipline/build.gradle.kts' line: 155

Still running into this on fresh clones of zipline.

Anybody know if this is still happening in zipline? I did a clean clone build with the deleted local konan dir and it didn't crash.

It's still an issue with the library, I'm sure. We're assuming kotlin native has been downloaded already. I want to see if there's a way to get the download to happen before we need it, or to just ship the jar with cklib. The issue is that we're using a jar that kotlin native doesn't post as it's own dependency, so we can't just add it to the gradle config. It also may be feasible to delay calling it until after task config. Looking at it now, but if the builds aren't failing, it's a different priority.

I’m setting up a new workstation tomorrow; I’ll post an update here either way.

[kpgalligan]

Any particular branch in zipline? I've been trying jwilson.0105.kt_16, assuming that's the config that will be in place for 1.6.10.

I ran into this today:

This happens when Zipline is the first KMM project you set up.

We get the same crash on all cklib releases preceding 0.2.4 because the host architecture was hardcoded to x86_64.

https://github.com/touchlab/cklib/blame/9377d335a18c030d06b3fae2d9f063fec7646398/plugin/src/main/kotlin/co/touchlab/cklib/gradle/CKlibGradleExtension.kt

Fix is to upgrade to 0.2.4 or newer, which has the caveat of requiring Kotlin 1.6.
