I am kind of out of ideas here. This doesnt look like an obvious issue with the plugin but I can't find anyone else sharing a similar issues. Is it possible that a downstream dependency is missing a dependency or do I need to add an additional dependency manually?

I am getting the following stack trace

Caused by: java.lang.ClassNotFoundException: org.apache.jasper.compiler.Node$CustomTag

I upgraded to jspc-compiler-tomcat8 to see if it made a difference and the class not found exceptions disappeared. Looks like something down the tomcat7 dep chain is broken making it unusable.

Thanks for reaching out @ksmith97!
Could you check mvn dependency:analyze and mvn dependency:tree to see what versions are being pulled in and if any dependencies are missing?

@ChristianMurphy Unfortunately, its impossible for me to know if a dependency is missing if it isn't there in the first place! I did look through the dependency tree but I did not see anything glaringly wrong.

I spent some time looking but I honestly don't know an easy way to figure out where the class should have come from. It is interesting that ecj is not at one of their regular build numbers for tomcat7 though.

Hey there! 👋

Thanks for opening an issue with jspc-maven-plugin. 👍 🙇‍♂️
At the moment, the jspc maven plugin does not have an active maintainer to process your request. ⛔
While the Jasig jspc maven plugin is without an active maintainer, we recommend the Apache Sling jspc maven plugin and the Jetty jspc maven plugin as alternatives that are actively maintained. ✅
If you are interested in becoming a project maintainer, there is a uPortal-dev list post where you can register your interest. 📧

Thanks again for contributing to the jspc-maven-plugin! ✨
