I’ve been unable to build codenameone Android Gradle Projects since upgrading on NetBeans 12.6 to codenameone-maven-plugin:7.0.150. Receiving the following error message:
Generating android gradle Project to /Users/mike/IT/NetBeansProjects/myapp/android/target/myapp-android-1.0-SNAPSHOT-android-source...

As Shai suggested, I created MyTestApp from Codename One Initializr at start.codenameone.com.
It runs fine from the command line on JDK 17 but fails on the android build ./build.sh android_source
Does that mean there is a compatibility issue with JDK 17 and I should be using a different Java JDK? Here’s a few key lines of output:

Changing the Java 17 folder name from jdk-17.jdk to jdk-17.0.11.jdk fixed the problem.
Originally
JDK 17 Foldername:
/Library/Java/JavaVirtualMachines/jdk-17.jdk
In .zshrc file:
export JAVA17_HOME='/Library/Java/JavaVirtualMachines/jdk-17.jdk/Contents/Home'
echo $JAVA17_HOME:
/Library/Java/JavaVirtualMachines/jdk-17.jdk
/Contents/Home was missing from echo'd path
Revised
JDK 17 Foldername:
/Library/Java/JavaVirtualMachines/jdk-17.0.11.jdk
In .zshrc file:
export JAVA17_HOME='/Library/Java/JavaVirtualMachines/jdk-17.0.11.jdk/Contents/Home'
echo $JAVA17_HOME:
/Library/Java/JavaVirtualMachines/jdk-17.0.11.jdk/Contents/Home
/Contents/Home doesn't get clipped!
