Eclipse classpath.file.whenMerged hook breaks confusingly for non-java projects

    Details

    • Type: Bug
    • Status: Open

      Description

      subprojects {
        apply plugin: 'eclipse'
        eclipse.classpath.file.whenMerged { }
      }
      

      Above only works if the subproject has a JavaBase plugin applied. If not various script compile time errors occur, for example:

      Could not find method whenMerged() for arguments [build_22ci319j0o3fipj4dom75lr8dj$_run_closure2_closure4_closure5@71dd95c]

      We should look into ways of improving the dsl / error message and perhaps review the samples / docs that mention classpath.file.whenMerged feature.

      Workarounds:

      1. Apply java plugin (or some other plugin, that also applies JavaBase plugin) before applying the eclipse plugin.
      2. Use plugins.withType:

      subprojects {
        apply plugin: 'eclipse'
        plugins.withType(JavaBase) {
          //now we can manipulate the .classpath file:
          eclipse.classpath.file.whenMerged {}
        }
      }

        Can you please provide the full error message. There's a section about which object the `whenMerged()` method is actually being called on missing.

        If in doubt, please just provide the whole output.

        The problem is because classpath file is not generated for all projects but only for projects that have the java plugin (strictly speaking: the JavaBase plugin). To fix the problem you can:

        subprojects {
        plugins.withType(JavaBase) {
        eclipse.classpath.file {
        ...
        }
        }
        }

        The exception is not great. We should definitely improve Gradle's bahavior in this scenario. I'll create a jira ticket for it.

        Hope that helps!
