Trying to use zt-zip in a Jenkins and I get the following error

java.lang.LinkageError: loader constraint violation: when resolving method "org.slf4j.impl.StaticLoggerBinder.getLoggerFactory()Lorg/slf4j/ILoggerFactory;" the class loader (instance of hudson/PluginFirstClassLoader) of the current class, org/slf4j/LoggerFactory, and the class loader (instance of org/eclipse/jetty/webapp/WebAppClassLoader) for the method's defining class, org/slf4j/impl/StaticLoggerBinder, have different Class objects for the type org/slf4j/ILoggerFactory used in the signature

Any idea what I can do to fix this?

Judging by the error message, you have SLF4J JAR file in Jenkins plugin and in Jetty webapp classloader. Nothing to do with zt-zip, you have to fix your environment.

I had <pluginFirstClassLoader>true</pluginFirstClassLoader> in my POM and I guess this was causing the conflict. I removed that and then I was able to compile the plugin. It's strange that I only got this issue with zt-zip and other dependencies don't. Maybe only zt-zip uses slf4j and others don't? I really hope I won't have to go back to <pluginFirstClassLoader>true</pluginFirstClassLoader> as I'll have no idea how to solve this conflict then.
