I couldn't get how to reproduce the problem.

• How do you archive artifacts in job1?
• "lastSuccessfulBuild" is build #510?
• Are there files in D:\jenkins\jobs\job1\modules\my.package$myapp\builds\510\archive ?

How do you archive artifacts in job1?

It is a Maven project. The advanced settings are:

• Disable automatic artifact archiving

And then the post-build actions have this action:

• Archive the artifacts

And I can see from the job page that the artifacts are archived.

"lastSuccessfulBuild" is build #510?

Yes, and it does have downloadable artifacts.

Are there files in D:\jenkins\jobs\job1\modules\my.package$myapp\builds\510\archive ?

No, because module archiving was disabled. The 510 directory exists but not the archive subdirectory. The archived artifacts are in D:\jenkins\jobs\job1\builds\510\archive.

Could not reproduce in my environment.
Please let me know the detailed steps to reproduce the problem.

Tested steps (tested with Windows 8.1 64bits, Java 1.7.0_79):

1. Install and launch jenkins.1.625.2.
2. Install following plugins:
   • copyartifact-plugin (tested with 1.37)
   • git-plugin (tested with 2.4.0, requires restarting Jenkins)
3. Setup maven in Manage Jenkins > Configure System (tested with maven-3.1.1)
4. Create a maven project "job1"
   • Git repository: https://github.com/jenkinsci/copyartifact-plugin.git
   • Goals and options: package -DskipTests=true
   • Check "Disable automatic artifact archiving" in the advanced section.
   • Add "Archive the artifacts" to "Post-build Actions"
     • Files to archive: target/*.hpi
5. Run "job1". job1 #1 will finish successfully.
6. Create a freestyle project "job2"
   • Add "Copy artifacts from another project"
     • Project name: job1
     • Which build: Last successful build
     • Artifacts to copy: **/*
7. Run "job2"

Result:

• job2 #1 succeeds.
• The log was:

  Started by user anonymous
  Building in workspace C:\Users\ikedam\.jenkins\jobs\job2\workspace
  Copied 1 artifact from "job1" build number 1
  Unable to access upstream artifacts area C:\Users\ikedam\.jenkins\jobs\job1\modules\org.jenkins-ci.plugins$copyartifact\builds\1\archive. Does source project archive artifacts?
  Finished: SUCCESS
  

  • The warning log was output as copyartifact scans all modules for artifacts. But that doesn't affect the build result.
• job2 succeeds also with "Specified by permalink" and "lastSuccessfulBuild"

Cannot reproduce.
Please reopen this issue when you report detailed steps to reproduce the problem.

To reproduce this problem, you must use the same steps as in the details. In addition, the very first step is to include the following: at jenkins global configuration at "Artifact Management for Builds" section need add "Compress Artifacts". (sorry for my english)

Copyartifact doesn't support ArtifactManager (JENKINS-22637).
It will be supported in copyartifact-1.40.
