Jenkins ver. 2.73.3 MacOSx
Doing an iOS build and upload to hockeyapp. The .ipa is created successfully, error seems to happen afterwards, seems like on the hockeyapp upload. I have an android project that works and uploads to hockeyapp successfully though.
Started getting this today after updating Jenkins and plugins. Was working before.
Any ideas?
回答1:
happened to me when running an Android build (Jenkins build 2.86, I just downgraded from 2.87 or something slighlty newer, because of other fails)
Build step 'Invoke Gradle script' changed build result to SUCCESS

I remembered that recently I have installed java 9 for experimenting, but still having java 8 set to usl/libexec/java_home, in my .zshrc like:
export JAVA_HOME=`/usr/libexec/java_home -v 1.8.0_152`
but that did not help at all, so I said goodbye to Java 9 with
sudo rm -rf /Library/Java/JavaVirtualMachines/jdk-9.0.1.jdk
then went to Manage Jenkins -> Configure System -> Environment variables and added
/Library/Java/JavaVirtualMachines/jdk1.8.0_152.jdk/Contents/Home
as JAVA_HOME
after Jenkins restart my builds run like a charm
回答2:
While staying with Java 8, wiping the current workspace on Jenkins got rid of the error for me. Got the error after updating gradle and the sonarqube plugin version.
