Help! java.lang.NoClassDefFoundError from java.lang.ClassNotFoundException #13

Closed Stonley890 closed 1 year ago

Stonley890 commented 1 year ago

I'm trying to use this in a Spigot plugin but at runtime, it fails with java.lang.NoClassDefFoundError: org/shanerx/mojang/Mojang from Caused by: java.lang.ClassNotFoundException: org.shanerx.mojang.Mojang. I'm not super familiar with all this but I think this is an issue with Maven not bundling the Mojang class? There are no errors or problems in my IDE (VS Code). The file (from mvn -s settings.xml install -f pom.xml) is zipped below.

eyeofonyx-1.0.0.jar.zip

Here is the error when run:

Solved. The maven shade plugin was inside pluginConfiguration.
