Hi guys, This is an issue I'm facing for a long time now, without having managed to find the root cause.
Some of our plugin tests are randomly failing. Our test suite is using the Jenkins test harness, and I can't manage to find the root cause. Only a few tests among all the test suite are affected. For example this simple one: https://github.com/SonarSource/sonar-scanner-jenkins/blob/master/src/test/java/hudson/plugins/sonar/MigrationTest.java hudson.plugins.sonar.MigrationTest.testShouldMigrateDatabasePasswords(hudson.plugins.sonar.MigrationTest) Run 1: MigrationTest.testShouldMigrateDatabasePasswords:56 NullPointer Run 2: MigrationTest.testShouldMigrateDatabasePasswords:56 NullPointer Run 3: MigrationTest.testShouldMigrateDatabasePasswords:56 NullPointer Run 4: MigrationTest.testShouldMigrateDatabasePasswords:56 NullPointer Run 5: MigrationTest.testShouldMigrateDatabasePasswords:56 NullPointer It look like the plugin under test is sometimes not properly loaded in the Jenkins instance. I can even reproduce by running this test alone: mvn clean verify -Dtest=MigrationTest After a few runs, I get: Running hudson.plugins.sonar.MigrationTest Feb 27, 2017 12:16:29 PM org.eclipse.jetty.util.log.Log initialized INFO: Logging initialized @355ms Exploding /home/julien/.m2/repository/org/jenkins-ci/main/jenkins-war/2.32.2/jenkins-war-2.32.2-war-for-test.jar into /home/julien/Prog/Projects/jenkins-sonar-plugin/target/jenkins-for-test Feb 27, 2017 12:16:31 PM org.eclipse.jetty.server.Server doStart INFO: jetty-9.2.12.v20150709 Feb 27, 2017 12:16:31 PM org.eclipse.jetty.webapp.StandardDescriptorProcessor visitServlet INFO: NO JSP Support for /jenkins, did not find org.eclipse.jetty.jsp.JettyJspServlet Feb 27, 2017 12:16:31 PM org.eclipse.jetty.server.handler.ContextHandler doStart INFO: Started o.e.j.w.WebAppContext@3a3e78f{/jenkins,file:/home/julien/Prog/Projects/jenkins-sonar-plugin/target/jenkins-for-test/,AVAILABLE}{/home/julien/Prog/Projects/jenkins-sonar-plugin/target/jenkins-for-test} Feb 27, 2017 12:16:31 PM org.eclipse.jetty.server.AbstractConnector doStart INFO: Started ServerConnector@7ca33c24{HTTP/1.1}{localhost:39063} Feb 27, 2017 12:16:31 PM org.eclipse.jetty.server.Server doStart INFO: Started @1903ms Feb 27, 2017 12:16:31 PM org.jvnet.hudson.test.JenkinsRule createWebServer INFO: Running on http://localhost:39063/jenkins/ Loading $JENKINS_HOME from /home/julien/Prog/Projects/jenkins-sonar-plugin/target/test-classes/hudson/plugins/sonar/MigrationTest Feb 27, 2017 12:16:31 PM jenkins.InitReactorRunner$1 onAttained INFO: Started initialization Feb 27, 2017 12:16:35 PM jenkins.InitReactorRunner$1 onAttained INFO: Listed all plugins Feb 27, 2017 12:16:35 PM jenkins.bouncycastle.api.SecurityProviderInitializer addSecurityProvider INFO: Initializing Bouncy Castle security provider.
