I have tried to edit and edit maven-compiler-plugin version to older one but that doesn't solve the problem

Also i have run on 3.3.9-jdk8 on mule with gitlab ci/cd. This is little older project and it was manually having changes applied on the server directly, so i wanted to integrate in gitlab so it will run good with automatic ci/cd

Thanks

Answer 1

The problem is in the Java code of the project as the error messages say. Fix those and it should comoile. It has nothing to do with Mule nor Maven. They are Java programming errors.

The project is certainly a mess, that's for sure. The Java files without packages or an incorrect directory, and the basic conversion errors are a good hint. The description of the Maven says it is a Mule 4.3 application but it is a Mule 3.8 project. And the names of the files don't even follow Java convention for classes. com.mess indeed.
