Has anyone gotten Custom NiFi Processor Projects built using Gradle?

Unfortunately, Cloudera seems to only actively maintain a maven plugin for packaging the code into a nar file. My company has a standard to do things in gradle and do not want me changing to a maven project. Previously, we used a project compatible with gradle 6. Now we are upgrading to Java 17 and Gradle 8.8 and what we had previously used is now incompatible so I was wondering if anyone has had luck with this issue?

Hi @mjmoore ,

Im not gradle expert but it seems like it has plugins for nifi:

https://plugins.gradle.org/search?term=nifi

will that work?

If you are only building a custom NAR, you should be able to use one of the Gradle plugins from the list that was posted here. Building all of NiFi as a Gradle project may not be quite as feasible, but I believe a 'gradle init' can (almost?) convert the project into a Gradle build. You may also want to look at Gradle plugins that are similar to the Maven plugins we use for the project such as identifying vulnerabilites in dependencies, checkstyle (if you have such a requirement), etc.

Yes its only for custom processors so looking at the two libraries linked one was abandoned in 2020 and it looked like there would compatibility issues with gradle 8. I will have to check the other one and get back to you.
