How to force the installation of a plugin using the JenkinsRule?

[Victor Martinez]

Hi there,

 I'm using the JenkinsRule in the test phase of a particular plugin development and I would like to know how I can install a particular plugin in the UT phase. For instance:

 

pom.xml

...

  <dependencies>

    <dependency>

      <groupId>org.jenkins-ci.plugins</groupId>

      <artifactId>gradle</artifactId>

      <version>1.24</version>

      <scope>test</scope>

    </dependency>
...

// functional code

if (Jenkins.getInstance().pluginManager.getPlugin("gradle") != null) {
   LOG.log(Level.FINE, "Gradlew is installed");
} else {
   LOG.log(Level.FINE, "Gradlew is NOT installed");
}

// UI

@Test public void testJobWithGradlew() throws Exception {

        FreeStyleProject project = j.createFreeStyleProject("WithWrapper");

        project.getBuildersList().add(new hudson.plugins.gradle.Gradle("description","switches","tasks","rootBuildScriptDir","buildFile","gradleName", true, false, false, false));

        assertFalse(checker.executeCheck(project));

}

        

For some reason the gradle plugin is not installed when I run mvn test, actually it's not installed and I don't see those traces when I run the testJobWithGradlew test. How can I force that plugin to be installed in the Test Instance?

Thanks
