The name of the project to copy artifacts from.

Maven projects:

Artifacts from all modules will be copied. Enter JOBNAME/MODULENAME here to copy from a particular module; you may copy/paste this from the URL for that module when browsing Jenkins.
Example: MyMavenJob/my.group$MyModule

Matrix projects:

Artifacts from all configurations will be copied, each into a subdirectory with the name of the configuration as seen in its URL when browsing Jenkins.
Example: If the target directory is given as fromMatrix then the copy could create $WORKSPACE/fromMatrix/label=agentA/dist/mybuild.jar and $WORKSPACE/fromMatrix/label=agentB/dist/mybuild.jar.

To copy from a particular configuration, enter JOBNAME/AXIS=VALUE,.. as seen in the URL for that configuration.
Example: MyMatrixJob/jdk=Java6u17

To copy artifacts from one matrix project to another, use a parameter to select the matching configuration in the source project.
Example: OtherMatrixJob/jdk=$jdk

Multibranch Pipeline projects:

Use a path consisting of the project name followed by the branch name.
Example: /MyMultibranchProject/MyBranch

Special letters like '/' in branch names should be escaped. You can see the exact name in "Full project name" in job pages of each branch.
Example: ../MyMultibranchProject/feature%2Fnavigation
