I tried to make a new pipeline processor function, based on the blog example: https://www.graylog.org/blog/71-writing-your-own-graylog-processing-pipeline-functions
For some reason, mvn gives the following error:
[ERROR] /home/kex/workspace/graylog-plugin-function-tagmatcher/src/main/java/com/example/plugins/tagmatcher/XMLTagMatcherFunction.java:[107,19] cannot find symbol
[ERROR] symbol: class ParameterDescriptor
What would be the proper import to add to make this work? Or am I doing something else wrong here?
