Title: Message Title

Gowtham Subramanian created an issue   Jenkins / JENKINS-61261 Ivy ClassNotFoundException when using Grab Issue Type: Bug Assignee: Daniel Heid Components: core, postbuildscript-plugin Created: 2020-02-27 20:07 Environment: Jenkins LTS docker Labels: groovy classpath jenkins ivy Priority: Major Reporter: Gowtham Subramanian We are getting the below exception when we try to initialize and configure Jenkins plugins through post build Groovy Script under init.groovy.d. We understood this is the issue with classloader not able to find ivy in its path. However, this is working with 2.176.2 and started breaking from 2.176.3.     @Grab('org.yaml:snakeyaml:1.17') import java.util.logging.Logger import org.codehaus.groovy.control.CompilerConfiguration import org.yaml.snakeyaml.Yaml ....     java.lang.ClassNotFoundException: org.apache.ivy.core.settings.IvySettings at java.net.URLClassLoader.findClass(URLClassLoader.java:382) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) at org.eclipse.jetty.webapp.WebAppClassLoader.loadClass(WebAppClassLoader.java:565) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) Caused: java.lang.NoClassDefFoundError: org/apache/ivy/core/settings/IvySettings       We performed various work around to resolve this and none of them were successful   Job-DSL or Event Listener plugin cannot used since this is a config script which execute before Jenkins plugin installation/configuration. Similarly none of the pipeline utilities steps can be used at this point.   Cannot copy Ivy.jar to $Jenkins_Home/war/WEB_INF/lib due to the fact we run Jenkins as a docker container and war path will be only exposed after docker run which eventually invokes init.groovy.d script.   Tried adding the jar through classloader.     Add Comment   This message was sent by Atlassian Jira (v7.13.12#713012-sha1:6e07c38) -- You received this message because you are subscribed to the Google Groups "Jenkins Issues" group.
