Title: Message Title

Ulli Hafner created an issue   Jenkins / JENKINS-55349 Duplicate symbols in different plugins cause NPEs Issue Type: New Feature Assignee: Share Cheng Components: code-coverage-api-plugin, warnings-ng-plugin, workflow-cps-plugin Created: 2018-12-27 23:27 Priority: Minor Reporter: Ulli Hafner If two different plugins define the same symbol name in steps or parameters then the workflow cps plugin can't instantiate the right element. I.e., in JENKINS-55328 a user created a step recordIssues tools: [checkStyle(), pmd(pattern: 'target/pmd.xml'), spotBugs(), cpd(pattern: 'target/cpd.xml')] Since the user already installed the PMD plugin, the symbol pmd has been reserved for the step in the PMD plugin already. That means, rather then providing the pmd tool to my recordIssues step, it started the pmd step and set the corresponding array element to null. The same happened in JENKINS-53181. In the comments Jesse Glick noted that this behavior could not be changed (or is hard to change). It would help other plugin developers, if in such cases at least the workflow-cps engine could provide a meaningful exception (with the conflicting Jenkinsfile line) rather then assigning null to a parameter.
