I have a CI build that always uses an init script. Every once in a while the build fails with the following error message:
Starting Build
FAILURE: Build failed with an exception.
* What went wrong:
Could not load compiled classes for initialization script 'init.gradle' from cache.
This is can be fixed by deleting the workspace.
I’m running milestone 9 on linux. Gradle home is set to a local directory.
Can you run with the ‘-s’ (show stacktrace) switch and provide the exception trace please.
I’ve turned on stacktraces on the CI server builds and will post the stacktrace next time the problem recurs.

Anyone?
I thought I should mention that this problem has been popping every once in a while through a number of gradle releases – it is not new to milestone 9.
I’ve raised this as issue GRADLE-2249.
I’m unsure what’s going on at this time.
Hello David, I would like to reproduce your problem. Can you give some more details about your setup and how you use gradle with your CI server.
What ci server do you use? - How do you invoke gradle in your build jobs? CI plugin, bash, gradle wrapper? - Have you multiple jobs on your CI that use this init script? - where is that init script located to?
Do you reference this init script via -i or do you put in the init.d folder of your gradle distribution? - Do you use different gradle versions on your CI?
regards, René
Please let me know if you have any additional questions.
Jenkins
I call it with bash. Here is a sample command line:
./gradlew --full-stacktrace --info --init-script gradle/hudson.init.gradle --gradle-user-home /tmp/hudson/workspace/job/gradle/gradle-user-home clean build
No, only one. There is complete separation of job workspaces; all sources and output are exclusive to that Jenkins job.
Inside the checked out sources.
No.
Hello, we have the same problem on Bamboo.
