Steffen Gebert added a comment - 2017-08-25 13:10 - edited Auto-generated DSL only shows multibranchPipelineJob -> branchSources -> branchSource -> source -> github -> traits -> originPullRequestDiscoveryTrait , not the other traits.

Daniel Spilker added a comment - 2017-08-27 21:44 The Automatically Generated DSL does not show traits because the structs plugin does not handle wildcards well in generic type declarations. See JENKINS-26535 . To reproduce this, run the following script in Script Console: import org.jenkinsci.plugins.structs.describable.DescribableModel import org.jenkinsci.plugins.github_branch_source.GitHubSCMNavigator new DescribableModel(GitHubSCMNavigator) The output is: Result: GitHubSCMNavigator(repoOwner: String , apiUri?: String , buildForkPRHead?(deprecated): boolean , buildForkPRMerge?(deprecated): boolean , buildOriginBranch?(deprecated): boolean , buildOriginBranchWithPR?(deprecated): boolean , buildOriginPRHead?(deprecated): boolean , buildOriginPRMerge?(deprecated): boolean , credentialsId?: String , excludes?(deprecated): String , includes?(deprecated): String , pattern?(deprecated): String , scanCredentialsId?(deprecated): String , traits?: java.lang.UnsupportedOperationException: do not know how to categorize attributes of type jenkins.scm.api.trait.SCMTrait<? extends jenkins.scm.api.trait.SCMTrait<?>>[])

Steffen Gebert added a comment - 2017-08-28 05:40 - edited Thanks Daniel for your quick feedback. Actually, it is showing the traits section to me, but lacking all but the originPullRequestDiscoveryTrait . Maybe it is working and the issue is only my naive try to specify it: source { github { id( 'my-repo' ) repoOwner( 'my-org' ) repository( 'my-repo' ) credentialsId( 'github-token' ) apiUri( 'https: //api.github.com' ) } traits { originPullRequestDiscoveryTrait { strategyId(1) } } } This results in ERROR: (script, line 24) No signature of method: javaposse.jobdsl.plugin.structs.DescribableListContext.traits() is applicable for argument types: (script$_run_closure1$_closure2$_closure6$_closure7$_closure10) values: [script$_run_closure1$_closure2$_closure6$_closure7$_closure10@d804df7] Possible solutions: wait(), wait(long), wait(long, int), split(groovy.lang.Closure), withTraits([Ljava.lang.Class;), is(java.lang.Object) It's listing a withTraits() method. Can we call this somehow? I've attached a config.xml of a manually created multi-branch job (including the <traits>  section).  multibranch-config-manual.xml

Daniel Spilker added a comment - 2017-08-28 08:26 This bug report was originally about the github-organization-folder-plugin but is actually a problem with the branch sources (see below), so it applies to workflow-multibranch as well. stephenking I see a lot of traits in my embedded API viewer (Jenkins 2.19.1, latest version of all plugins), but not the org.jenkinsci.plugins.github_ branch source.BranchDiscoveryTrait and org.jenkinsci.plugins.github branch _source.ForkPullRequestDiscoveryTrait traits from your config XML. To debug the problem, I ran the following script in Script Console: import org.jenkinsci.plugins.structs.describable.DescribableModel import org.jenkinsci.plugins.github_branch_source.GitHubSCMSource new DescribableModel(GitHubSCMSource) The output is (formatted for readability): GitHubSCMSource( repoOwner: String , repository: String , apiUri?: String , buildForkPRHead?(deprecated): boolean , buildForkPRMerge?(deprecated): boolean , buildOriginBranch?(deprecated): boolean , buildOriginBranchWithPR?(deprecated): boolean , buildOriginPRHead?(deprecated): boolean , buildOriginPRMerge?(deprecated): boolean , credentialsId?: String , excludes?(deprecated): String , id?: String , includes?(deprecated): String , traits?: SCMSourceTrait{AuthorInChangelogTrait() | CheckoutOptionTrait(extension: CheckoutOption(timeout: int )) | CleanAfterCheckoutTrait() | CleanBeforeCheckoutTrait() | CloneOptionTrait(extension: CloneOption(shallow: boolean , noTags: boolean , reference: String , timeout: int , depth?: int , honorRefspec?: boolean )) | ForkPullRequestDiscoveryTrait(strategyId: int , trust: java.lang.UnsupportedOperationException: do not know how to categorize attributes of type jenkins.scm.api.trait.SCMHeadAuthority<? super org.jenkinsci.plugins.github_branch_source.GitHubSCMSourceRequest, ? extends jenkins.scm.api.mixin.ChangeRequestSCMHead2, ? extends jenkins.scm.api.SCMRevision>) | GitBrowserSCMSourceTrait(browser: GitRepositoryBrowser{AssemblaWeb(repoUrl: String ) | BitbucketWeb(repoUrl: String ) | CGit(repoUrl: String ) | FisheyeGitRepositoryBrowser(repoUrl: String ) | GitBlitRepositoryBrowser(repoUrl: String , projectName: String ) | GitLab(repoUrl: String , version: String ) | GitList(repoUrl: String ) | GitWeb(repoUrl: String ) | GithubWeb(repoUrl: String ) | Gitiles(repoUrl: String ) | GitoriousWeb(repoUrl: String ) | GogsGit(repoUrl: String ) | KilnGit(repoUrl: String ) | Phabricator(repoUrl: String , repo: String ) | RedmineWeb(repoUrl: String ) | RhodeCode(repoUrl: String ) | Stash(repoUrl: String ) | TFS2013GitRepositoryBrowser(repoUrl: String ) | ViewGitWeb(repoUrl: String , projectName: String )}) | GitLFSPullTrait() | GitToolSCMSourceTrait(gitTool: String ) | IgnoreOnPushNotificationTrait() | LocalBranchTrait() | OriginPullRequestDiscoveryTrait(strategyId: int ) | PruneStaleBranchTrait() | RefSpecsSCMSourceTrait(templates: RefSpecTemplate(value: String )[]) | RegexSCMHeadFilterTrait(regex: String ) | RemoteNameSCMSourceTrait(remoteName: String ) | SSHCheckoutTrait(credentialsId: String ) | SubmoduleOptionTrait(extension: SubmoduleOption(disableSubmodules: boolean , recursiveSubmodules: boolean , trackingSubmodules: boolean , reference: String , timeout: int , parentCredentials: boolean )) | UserIdentityTrait(extension: UserIdentity(name: String , email: String )) | WildcardSCMHeadFilterTrait(includes: String , excludes: String ) | WipeWorkspaceTrait() | jenkins.plugins.git.traits.BranchDiscoveryTrait~BranchDiscoveryTrait() | org.jenkinsci.plugins.github_branch_source.BranchDiscoveryTrait~BranchDiscoveryTrait(strategyId: int )}[]) As one can see, the problem with ForkPullRequestDiscoveryTrait is that the trust property is not supported by structs-plugin, probably because of JENKINS-26535 . The BranchDiscoveryTrait is not available because there are two classes named BranchDiscoveryTrait in different packages ( jenkins.plugins.git.traits and org.jenkinsci.plugins.github_branch_source ). Job DSL only uses the class name to determine the class and for BranchDiscoveryTrait that's ambigious, so it's not available. github-branch-source-plugin and/or git-plugin can use a @Symbol annotation to set an unambigious alias. IMHO this needs to fixed in github-branch-source-plugin, git-plugin and/or structs-plugin. Pinging stephenconnolly , markewaite and jglick .

Alex Richardson added a comment - 2018-06-07 12:28 I ran into this issue today, have there been any changes to make this work? Or do I still need to use the workaround of manually adding to the XML in the configure block?

John Lonergan added a comment - 2018-07-04 17:16 +1 it would be helpful to include a link to the resolution?
