Exception running 'grails clean' after upgrade to Grails 4.0.2

[Milan Zimmermann]

After upgrading to  Grails 4.0.2, on an existing project, I get an error:

grails clean --stacktrace --verbose
WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by org.codehaus.groovy.vmplugin.v7.Java7$1 (file:/home/mzimmermann/software/java-based/grails/lib/org.codehaus.groov

I tried multiple things with no luck. I am tracing this issue by looking at Grails sources:

this.profile = profileRepository.getProfile(profileName)

and from there to 

createMavenProfileRepository()

where it looks like 

def profileRepos = getSetting(BuildSettings.PROFILE_REPOSITORIES, Map.class, Collections.emptyMap())

is getting a null profileRepos. But I am not sure what to do; there was no issue in the previous version of Grails: 2.2.0

Anyone has any pointers?

Thanks

Are you using Java 7?

Grails 4 is not compatible with Java 7.

Thanks for getting back! I am using Java 11. Only Java 11 present on my system. Java, Groovy and Grails configured manually  using GROOVY_HOME and GRAILS_HOME. I am quite confident that part of the configuration is correct.

I should also say that on a freshly created app 'grails create-app' the 'grails clean' works. The problem is on an existing project (rather large) that I am trying to migrate. That was using Java 7 and I assume the reference to /home/mzimmermann/software/java-based/grails/lib/org.codehaus.gro
ovy/groovy/jars/groovy-2.5.6.jar
 

is from an pre-existing plugin.

Thanks

I wanted to say, I just managed to solve the 'grails clean' exception by creating a project with the same name, and gradually copying over some elements of the project. 

I still am having a huge amount of compile issues, but at least a step ahead.

To ask for help, what venue would you recommend? Slack? StackOverflow? 

Thanks again for getting back to me.

We have done many many upgrades and in general, that is the approach
that I advocate for. Having done it a bunch, it really isn’t as
tedious as it might sound at first. That usually goes quite smoothly.
I am glad you got it worked out.

There won’t be a general answer to how to fix compilation issues. The
resolutions will depend on what the errors are.

You can ask questions about how to address those here on the mailing
list, or in Slack, or on StackOverflow. Most folks have migrated away
from the mailing list in favor of the other 2, Slack for conversational
questions and StackOverflow for specific questions that have a specific
answer (not likely to require a discussion).

I hope that helps.

Thanks James. I will follow up on slack or stackoverflow - while making steps ahead, still having an overwheliming amount of issues and uncertainties. The differences between Grails 2.2 and 4 (well, 3 really) as huge on the size of app we have here.

Appreciate your help!

We have updated scores of apps from Grails 2 to Grails 3 and more
recently Grails 4. If there is anything we can do to help, never
hesitate to reach out. We are happy to help.

Thank you, will do that. I still feel I am able to move along for now. Not sure the direction is right, just making a step-by-step to get rid of errors as they show up.
