IJava % ./gradlew installKernel failed

[aaazzz640]

hi all,

I tried to setup the IJava based on the instructions however, after running cd IJava

then run $ chmod u+x gradlew && ./gradlew installKernel i got the problem like this:

FAILURE: Build failed with an exception.

• What went wrong: Could not create service of type ScriptPluginFactory using BuildScopeServices.createScriptPluginFactory().

Could not create service of type PluginResolutionStrategyInternal using BuildScopeServices.createPluginResolutionStrategy().

• Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

• Get more help at https://help.gradle.org

BUILD FAILED in 0s

Mine is es macos system and just got java 17 installed.

what might be the solution... many thanks :)

With --stacktrace and Ubuntu 20.04.3 and openjdk-17, I see:

...
Caused by: java.lang.IllegalAccessException: module java.base does not open java.lang to unnamed module @4d154ccd

With openjdk-11, I do not see the error above. Hence this is probably related to openjdk-17

Java 17 is supported only by gradle versions 7.3+. I created SpencerPark/Jupyter-kernel-installer-gradle#14 and SpencerPark/IJava#134 to bump gradle version to 7.4.2.
