Errors when running `skip checkup` if java version > 17

[Marsgames]

Error after first installation via brew and running skip checkup (with and without --double-check)

Maybe we can provide more info, to help resolving this issue?

^{Originally posted by oluarry October 27, 2023} This error came up when trying to build in xcode I followed all the steps and made 2 different projects but same error in xcode I ran skip doublecheck here

I got the same error, please keep me updated if you find the solution.

[KristofZelei]

I found the solution, I had a newer version of JDK installed. Follow this documentation to uninstall your current version if it is above 17 or simply install version 17.

Yep, working now. Thanks for your help!

cd /Library/Java/JavaVirtualMachines
sudo rm -rf JDK>17 # replace by your idk version
brew install openjdk@17

Issue can be closed (but info should be added to the installation readme?)

[DominatorVbN]

Even unistalling the newer JDK and installing openjdk@17 did not worked

• Set the path in zshrc as well

It only worked when i added below line to the Build Android APK build phase script

export JAVA_HOME="/opt/homebrew/opt/openjdk@17/libexec/openjdk.jdk/Contents/Home"
export PATH=$JAVA_HOME/bin:$PATH

[marcprux]

We released Skip 0.7.13 last night, which adds openjdk@17 as a dependency of the skip Homebrew package. Run skip upgrade from the command line and then ensure skip checkup passes to get the latest version. If it fails, please post the output of skip checkup --verbose.

Also, if you have a custom JAVA_HOME set (e.g. from your ~/.zshrc file), you may need to unset it for the process you run skip checkup and/or Xcode, otherwise Gradle may try to use an incompatible version.

For some background, Skip would like to be hands-off about which Java version it uses, since Android-focused developers may have limitations and needs for specific version. However, there's an open Gradle issue that prevents JDK 21 from working at all for Android builds; this is a problem for Homebrew's default recommended JDK temurin, which recently got bumped to version 21. So to work around that, we've added openjdk@17 as a prerequisite to Skip's Homebrew formula. In the future, we hope to enable developers to specify which JDK to use at the top-level (e.g., in Sources/App/Skip/skip.yml), but currently it is specified at the very lowest level of SkipUnit.

[tejuamirthi]

skip checkup passes with all checks but Build Android APK phase still fails.

I'm using Skip 0.7.13 but still facing the issue

This solution worked https://github.com/skiptools/skip/issues/5#issuecomment-1783770634

[shial4]

I had to add

JAVA_HOME=/usr/local/Cellar/openjdk@17/17.0.9/libexec/openjdk.jdk/Contents/Home
PATH=$JAVA_HOME/bin:$PATH

instead of /opt/homebrew/opt

[marcprux]

Skip 0.7.16 adds some additional logic to use the /opt/homebrew/opt/openjdk@17 installation rather than the /opt/homebrew/opt/openjdk@21 (which is installed by gradle). This should fix situations where the openjdk@21 install is inadvertently used (and thus triggering the Gradle issue with Java 21).

Please let us know if this problem still affects you and we will re-open the issue.

[rzil]

I am using latest Skip version 0.7.31 but still facing the above issues.

[marcprux]

Can you post the output of skip checkup --verbose?

Can you try forcing using openjdk 17 with the command:

brew link --overwrite openjdk@17

And then check the output of the java -version command:

[rzil]

I followed those steps but it didn't work. It seems skip is still choosing JDK version 21? Here is the output.

I had the same problem @rzil :

1. I installed skip using brew command, and by default the openjdk 21 is installed
2. I installed openjdk 17 and tried 'brew link --overwrite openjdk@17'
3. 'java -version' display the 17.0.9, but in skip checkup, the 21.0.1 is used

I fixed it, you can follow these instructions (not final fix):

1. Check your current JAVA_HOME path -> 'echo $JAVA_HOME', in my case it was empty
2. Update your JAVA_HOME path to the good version (17.0.9) -> 'export JAVA_HOME=$(/usr/libexec/java_home -v17.0.9)'
3. Run 'skip checkup' again, the version of Java should be 17.0.9

@marcprux Inside the homebrew configuration file , the openjdk@21 is used, maybe the issue could come from here? This is my first time searching for an error with Homebrew, so I might be mistaken.

[rzil]

Yes that did the trick. Need to set JAVA_HOME correctly. For some reason my java_home executable wasn't working but once I resolved that all good.

[roslog00]

Hello, how do I correctly change the JAVA_HOME path? It shows my path, but the tests are not working.

[marcprux]

Apologies for not getting back on this sooner. We're still working through some of the issues with Gradle 8.5 and OpenJDK. If you brew upgrade skip to 0.7.33, that version will try to automatically use opendk@17, and you can manually override if by setting export JAVA_HOME=/opt/homebrew/opt/openjdk@17/ from the terminal before running skip.

Please let us know if this helps.

I think that problem was a different one that should be resolved if you skip upgrade to 0.8.3 (released today). Please try it out and if skip checkup or skip init fails, let us know.

[marcprux]

Can you try running brew update and then skip upgrade again? It sounds like the Homebrew cache might not be updating automatically.

[mmmago]

Cannot make this work,

even by setting JAVA_HOME=$(/usr/libexec/java_home -v17.0.11). Kotlin also fails.

java -version returns :

openjdk version "17.0.11" 2024-04-16
OpenJDK Runtime Environment Homebrew (build 17.0.11+0)
OpenJDK 64-Bit Server VM Homebrew (build 17.0.11+0, mixed mode, sharing)

Any inputs ?

[marcprux]

As you seem to have surmised, this is the problem:

[!] Java version 1.8.0_411 (< 21.0.0) (check JAVA_HOME envrionment: /Library/Internet Plug-Ins/JavaAppletPlugin. plugin/Contents/Home)

You should remove any reference to JAVA_HOME in your ~/.zshrc or ~/.bashrc. Also, we do need JDK 21, not JDK 17. OpenJDK 21 should have been installed when you installed skip with the brew command. So if you remove JAVA_HOME from your environment and run skip checkup from a new shell (making sure that echo $JAVA_HOME does not return anything), then it should pick up the right one.

If that continues to fail, can you post the log file mentioned at the end of the command?

[mmmago]

I tried using JDK 17 because JDK 21 was not working as well. This is what is happening :

Here is the log attached :

Also, was your machine upgraded from an Intel to an ARM (e.g., M1)? If so, the Homebrew installation may be an old Intel-based version, which sometimes installs the wrong architecture for packages. In these cases (which can be identified by the existence of a /usr/local/Homebrew/ directory), we've found that performing a clean Homebrew re-install can help resolve issues.

Hello, sorry for the lack of news. Trying this again :

/opt/homebrew/opt/java does not exist. Performing brew reinstall openjdk does not solve the problem.

I do use a M1 Pro machine, /usr/local/Homebrew is indeed existing. Performing a clean install, it now looks like /opt/homebrew/opt/ is existing, but not the java folder, even after re-performing brew reinstall openjdk.

EDIT : I fixed it by running :

echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> ~/.zshrc

then

source ~/.zshrc
