The jenkins-test-harness framework does not seem to handle Jenkins' detached plugins properly. If one of the detached plugins bundled in the jenkins.war file is older than what is specified in a Gradle jenkinsPlugins dependency, both will get installed and when you try to run the local Jenkins test instance it complains that the older version is installed and refuses to install any dependencies that require the newer version.
This breaks tools like the Gradle JobDSL plugin as they are unable to specify a newer set of plugins to match a running Jenkins instance if some of those plugins are bundled at older versions in the jenkins-war artifact.
For instance, if you had a Jenkins instance running 2.190.2 with a set of plugins updated to be (more or less) current, and tried to use the jenkins-test-harness runner to execute DSL and create jobs on your Jenkins instance, it would complain that "SCM API Plugin version 2.4.1 is older than required. To fix, install version 2.6.3 or later." because 2.4.1 is what is bundled in the 2.190.2 jenkins-war file, even though a newer version should come in through a dependency on the latest Git plugin (e.g. Git 4.0.0).
When inspecting the test Jenkins instance spun up by the jenkins-test-harness, you will see that it has ended up installing BOTH versions of scm-api when it should have let the newer 2.6.3 version take precedence over 2.4.1. E.g. see this:
This can be reproduced with a simple Gradle project consisting of a build.gradle file, a sample job DSL, and a small class which uses the jenkins-test-harness to provision a test Jenkins instance. This can be found in the attached jenkins-test-harness.zip
file, in the jenkins-test-harness/steps-2.190.2 folder. To reproduce it there, run the following Gradle command:
cd jenkins-teat-harness/steps-2.190.2 gradlew clean testJenkins
Also included in the attached archive is a similar project but for Jenkins 2.176.3. In that version, Git 4.0.0 is not yet available so the build.gradle file specifies 3.12.0 and the jenkins-war bundled detached-plugins match what's in the build.gradle so there is no mismatch, and the test runner works okay. The difference between the two can be found in patch-2.176-to-2.190.diff
It is possible to make the above testJenkins task run successfully by using a custom TestPluginManager which skips loading the declared-plugins from the jenkins-war artifact entirely. This does mean the caller is then responsible for providing enough plugins to make their test harness run correctly. An example of that working can be found in the attached .zip archive as well, in a folder jenkins-test-harness/steps-patched. The difference between that and the steps-2.190.2 folder can be found in patch-skip-declared-plugins.diff(notably, the addition of an additional plugin that is required and not loaded from jenkins-war anymore, and the specification of a custom plugin manager for the JenkinsRule which handles creating the test instance.)
I am not entirely sure what the proper fix here is. If the jenkins-test-harness allowed a flag to indicate whether to load the detached-plugins folder from inside the jenkins-war file, that would allow us to avoid loading them and instead rely on the specific versions we need to match our running Jenkins instance. We are running with a local patch which does this for us and it works.... okay. However, it also seems odd that the jenkins-test-harness would install an older plugin from jenkins-war's detached-plugins when a newer one is already specified in the jenkinsPlugins dependency section of a build.gradle file. If it were smarter and did not try to keep the older version installed, the problem would likely disappear altogether. A third possibility would be for jenkins-war not to bundle a too-old version of scm-api anymore. I suspect the version currently bundled in jenkins-war:2.190.2 might come in transitively as I could not find any evidence of its being explicitly included there, but I might have missed something. However, keeping jenkins-war always updated with newer plugins seems somewhat counterintuitive and it would seem more flexible for jenkins-test-harness to avoid loading older/outdated plugins if they were bundled in the detached-plugins folder.
While running the above "gradle testJenkins" custom task is an easy way to actually inspect the test instance provisioned through the test harness, it is of course also possible to run the test harness "the usual way". When run on the 2.176.3 version of the small sample project, everything is okay and it runs as follows:

See jenkins-test-harness.zip for the three projects that can be used to reproduce this.
I was not entirely sure what project to file this issue with. While jenkins-war probably falls under core, there was an earlier ticket filed at https://issues.jenkins-ci.org/browse/JENKINS-59722 which got closed as being "not a bug" there. I am filing this under the jenkins-test-harness component now because based on my troubleshooting, I think it is behaving erroneously and should either do the right thing and not install 2 different versions of a plugin if an older one was found in the jenkins-war detached plugins, or allow people to exclude the loading of detached-plugins through some sort of flag. Another related ticket was found for https://github.com/heremaps/gradle-jenkins-jobdsl-plugin/issues/129 but given that the problem (and fix, or at least my local hack) all occur outside of the gradle-jenkins-jobdsl-plugin I am not convinced that's the right place to look for a fix.
Very curious what the core Jenkins maintainers think of this. I hope my sample projects (and hackish workaround) help illustrate better what we're running into here. My hackish workaround with which we are currently running locally can be found at https://github.com/heremaps/gradle-jenkins-jobdsl-plugin/compare/3.7.0...robinverduijn:fix-jenkins-detached-plugins

Felix Mueller
added a comment - Unfortunately this issue also prevents me from testing my Jenkins Job DSL scripts, which makes the whole process very tedious. Vote +1 felix_r_mueller there's workaround for this in attached file [^patch-skip-declared-plugins.diff.]
To use it, I've created two files:
test/hudson/CustomPluginManager.groovy
package hudson import java.util.logging.Logger import org.jvnet.hudson.test.TestPluginManager /** * Modify plugin load behavior for jenkins for test */ class CustomPluginManager extends TestPluginManager { private static final Logger LOGGER = Logger.getLogger( CustomPluginManager.name ) // Skip loading all detached plugins as they conflict with our explicit build.gradle jenkinsPlugins dependencies @Override void considerDetachedPlugin( String shortName ) { LOGGER.fine( 'Skipping load of detached plugin: ' + shortName ) } }
test/hudson/CustomJenkinsRule.groovy
package hudson import org.jvnet.hudson.test.JenkinsRule /** * JenkinsRule to use in Job DSL scripts tests */ class CustomJenkinsRule extends JenkinsRule { CustomJenkinsRule() { super() this.pluginManager = new CustomPluginManager() } }
And in my test looks like this:
package com.example import javaposse.jobdsl.dsl.DslScriptLoader import javaposse.jobdsl.dsl.JobManagement import org.junit.ClassRule import hudson.CustomJenkinsRule import spock.lang.Shared import spock.lang.Specification import spock.lang.Unroll /** * Tests that all dsl scripts in the jobs directory will compile. */ class JobScriptsSpec extends Specification { @Shared @ClassRule CustomJenkinsRule jenkinsRule = new CustomJenkinsRule() @Unroll void 'test script #file.name'(File file) { given: Map <String, String> envVars = [ JENKINS_URL: 'http://ci.example.com', ] JobManagement jm = new JenkinsFileJobManagement(System.out, envVars, new File('.'), new File('build', 'xml')) when: new DslScriptLoader(jm).runScript(file.text) then: noExceptionThrown() where: file << new FileNameFinder().getFileNames('jobs', '**/*.groovy', '**/seed*').collect { new File(it) } } }
Possibly a Gradle-specific issue. Maven is recommended for Jenkins plugins.
v2v faced the same issue using a Jenkins rule to make some functional test(using maven), if you need an upper version of any of the detached plugins you are screwup, you have to use a custom TestPluginManager
Well a minimal, self-contained test case using Maven would be helpful for analysis. Possibly this was at root a core bug, so retest against a current version. I suspect that you would need JENKINS-41827 to accurately test this sort of thing in general.
It sucks this is marked as minor, practically any enterprise migrating over will have enough plugins to run into this 
Pretty much brings the idea of testing my changes before I deploy them in an easy way off the table, and I'll have to go with running two instances (dev/prod) and escalating dev into prod. CI/CDing my CI/CD server lol
Without any further information, assuming this is a problem in the Gradle harness, which is not very well maintained and is basically unsupported by Jenkins core developers. Maven is recommended.
jglick the problem with that is the JobDSL plugin test docs specifically call out and only provide examples for Gradle: https://github.com/jenkinsci/job-dsl-plugin/blob/master/docs/Testing-DSL-Scripts.md
I think I just found the issue, I was seeing these logs inside of the test instance when running the test command:

So, I took an actual look at how these jpi file names were being resolved, and it looks like Jenkins specifically wanted them to not have their version appended to the end. However, the default example located here doesn't parse the names in this way: https://github.com/jenkinsci/job-dsl-plugin/blob/master/docs/Testing-DSL-Scripts.md (specifically referring to the "resolveTestPlugins" task)
However, the author of this example does resolve the jpi file names correctly: https://github.com/sheehan/job-dsl-gradle-example/blob/master/build.gradle#L74
Replacing the "resolveTestPlugins" task with the one provided there seems to fix the issue for me
I've been going mad trying to figure out this same problem. For me the credentials plugin requires structs 1.20, but the test harness is bundled with 1.18.
I'm using the test harness to check Job DSL scripts, as in the example [automation starter|https://github.com/kamilszymanski/jenkins-jobdsl-automation-starter].
What's especially odd is that I'm having no problem running locally on my desktop, but consistently seeing this error running the Gradle project in a Jenkins build:
