Skip fails Kotlin, unable to build

[anjumkaiser]

Hi

I installed skip and ran skip checkup

it fails on Kotlin tests.

I ran skip checkup --verbose its log file is here:

skip-checkup-2024-06-09T11:50:54Z.txt

I did skip init as in document, it created project but building it in Xcode fails:
Build HelloWorld_2024-06-09T17-22-59.txt

There appear to be two separate issues here. First the checkup failure:

FAILURE: Build failed with an exception.

• What went wrong:
  Could not determine the dependencies of task ':app:generateReleaseLintVitalReportModel'.

Could not create task ':app:compileReleaseJavaWithJavac'.
Failed to calculate the value of task ':app:compileReleaseJavaWithJavac' property 'javaCompiler'.
> Cannot find a Java installation on your machine matching this tasks requirements: {languageVersion=21, vendor=any, implementation=vendor-specific} for MAC_OS on aarch64.
> No locally installed toolchains match and toolchain download repositories have not been configured.

Do you have a custom JAVA_HOME set in your environment? You can check with echo $JAVA_HOME from the Terminal. Also, can you post the output of which java and java -version?

Another historic cause of this issue is the scenario where the machine migrated from an Intel Mac to an ARM Mac, but the old Intel-specific Homebrew is still installed. You can identify this situation if you have /usr/local/homebrew/ (Intel) rather then the ARM version at /opt/homebrew/. If this applies in your case, the solution is to install Homebrew fresh from https://brew.sh and then re-install Skip.

Then the Xcode error:

error: An error occurred while performing transpilation: expected colon, near ""
Error: expected colon, near ""

This sounds like there might be a format error in your ~/.skiptools/skipkey.env file. Can you make sure it is in the form:

SKIPKEY: key

[anjumkaiser]

there was a new line before key, I removed it and tried again

skip checkup still fails at Kotlin:

I again tried building with Xcode, it gives different error this time
Build HelloWorld_2024-06-09T17-22-59.txt

I removed openjdk@22 and forced link openjdk@21 but that causes skip grade and android tests to fail.
are there specific dependencies I need to install?

I force removed kotlin@2 and openjdk@22 as they were installed by something else, then set following
~ export JAVA_HOME=/opt/homebrew/Cellar/openjdk@21/21.0.3
~ export PATH=$JAVA_HOME/jre/bin:$JAVA_HOME/bin:$PATH

this cause skip checkup to work:

I ran again:

skip init --open-xcode --appid=com.xyz.HelloSkip hello-skip HelloSkip

it fails to build with gradle related issues:
Build HelloSkip_2024-06-10T19-04-41.txt

seems dependencies will be a problem for now as there is already kotlin 2 and openjdk@22 is default in homebrew

is there a complete list of packages I need to have to get this to work?

[anjumkaiser]

I rebooted my Mac, it seems to skip checkup and skip init now works fine, skip test build debug build got android too.
but Xcode just fail at the same issue.

[marcprux]

I think the Xcode issue is just that you need to launch an Android emulator from the Android Studio Device Manager:

GRADLE> e: file://:0:0 No connected Android devices or emulators were reported by `adb devices`. To launch the Skip app, start an emulator from the Android Studio Device Manager or use the ~/Library/Android/sdk/emulator/emulator command
…
GRADLE> * What went wrong:
GRADLE> Execution failed for task ':app:installDebug'.
No connected Android devices or emulators were reported by `adb devices`. To launch the Skip app, start an emulator from the Android Studio Device Manager or use the ~/Library/Android/sdk/emulator/emulator command

GRADLE> > com.android.builder.testing.api.DeviceException: No connected devices!

Let us know if that helps.

And thanks for letting us know about the OpenJDK@22/Kotlin2 issue. There are some known issues with Kotlin 2 and Skip-transpiled code right now, but we should be able to co-exist side-by-side until we work out the issues. I'll look into it today.

[anjumkaiser]

ok

I think docs should be updated to mention a way, people with a new setup might need help with this.

steps to reproduce:

macOS Sonoma 14.5
XCode 15.4

brew install openjdk -> install openjdk v22
brew install gradle -> installs grade 8.8
brew install kotlin -> installs kotlin v2.0

and the issue pops up with skip init

thank you

[marcprux]

I just tried upgrading to openjdk@22 / gradle@8.8 / kotlin 2, and Skip does still work, provided the openjdk@21 is still installed (which it should be, since we depending on openjdk@21 on the Skip homebrew formula). I'll look into it some more, though – ideally, we would just work with whatever the latest openjdk is and not have to worry about it. But we did pin it to openjdk@21 when we migrated from openjdk@17 to ensure that the latest openjdk was going to be used.

[marcprux]

BTW, if you manually do brew install openjdk@21, does skip checkup pass for you?

[anjumkaiser]

I updated to latest skip, now checkup passes ok

I set team for signing and enabled skip plugin for Xcode

I started build from Xcode, it still fails

here is build export:

The underlying error from the log is:

GRADLE> > Cannot find a Java installation on your machine matching this tasks requirements: {languageVersion=21, vendor=any, implementation=vendor-specific} for MAC_OS on aarch64.

I'm able to build in 0.8.51
