[jira] [Created] (ARROW-9729) Error Prone causes other annotation processors to not work with Eclipse

Laurent Goujon created ARROW-9729:
-------------------------------------

             Summary: Error Prone causes other annotation processors to not work with Eclipse
                 Key: ARROW-9729
                 URL: https://issues.apache.org/jira/browse/ARROW-9729
             Project: Apache Arrow
          Issue Type: Bug
          Components: Java
            Reporter: Laurent Goujon
            Assignee: Laurent Goujon


An incompatibility between Eclipse (m2e-apt), Error Prone prevents other annotation processors to work correctly within Eclipse, which is especially an issue with Immutables.org annotation processor as it generated classes needed for the project to compile.

This is explained in more detailed in this bug report for m2e-apt Eclipse plugin: https://github.com/jbosstools/m2e-apt/issues/62

There's no easy workaround Eclipse user can apply by themselves, but the Arrow project could not include Error Prone as an annotation processor when being imported into Eclipse, in order for the other annotation processors to work.
