Using @grab to fetch SNAPSHOT jar in groovy sometimes can't be recoganized correctly if updating the SNAPSHOT

[pan]

Hi,

I got an issue when using @grab.
We are developing a jar and pipeline script to do the CI. We modify some
java code, deploy onto our internal Nexus server, use @grab in groovy to
fetch it to call the function.
During developing, we found when we modify some code, deploy a new SNAPSHOT
version with the same version number of jar, sometimes the pipeline script
is not working.

For example:

@GrabResolver(name='Internal Nexus Snapshot',

root='https://internal.nexus.com/')
@Grab('some-package:some-artifact:0.0.1-SNAPSHOT')
import some.Utils
println new Utils()

It works well, but if I deploy a new version to Nexus, it might fail,
unless I restart the Jenkins, then it will work again.

error message:

Running in Durability level: MAX_SURVIVABILITY
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
WorkflowScript: 1: unable to resolve class some.Utils
@ line 1, column 1.
@GrabResolver(name='Internal Nexus Snapshot', root='https://internal.nexus.com/')
^

I think it might be some cache in Jenkins, because restart Jenkins will fix
it. But I can't find it.
Does anyone have any clue about this?
Thank you very much.

Updates:

It might not be a good idea to use @grab in Jenkins pipeline script.

We also found an issue about this:
https://issues.jenkins-ci.org/browse/JENKINS-48974, this will cause the
parallel jobs which @grab the same direct/indirect dependencies failed.

It seems related to the groovy/ivy issue:
https://issues.apache.org/jira/browse/GROOVY-7407. And it’s not fixed yet

We also consider the way of @Library, but in the groovy lib, we still need
@grab 3rd party lib, which is the same situation.

Anyway, we refactor the dependencies into a service and call rest api from
the pipeline script, it seems working.
