Add apt generated source folder for Eclipse in build.gradle

[jsm174]

Overview of the feature request

I use Eclipse as my IDE. When pulling in JHipster microservices using gradle import, I have to add the apt generated source folder as per #2: https://www.jhipster.tech/configuring-ide-eclipse-gradle/

Anytime you refresh the gradle build, this entry gets lost. After doing this a million times, it is now getting old. :)

I'm not a gradle expert, but I tried adding a sourceSets entry in build.gradle and it works great:

idea {
  module {
    excludeDirs += files('node_modules')
  }
}

eclipse {
  sourceSets {
    main {
      java {
        srcDir 'build/generated/source/apt/main'
      }
    }
  }
}

If this seems correct, (or if there is a better way), I can make a PR.

@atomfrede : are you ok with that ?

Looks ok, but @jsm174 are you sure that configuration doesn't set the apt directory as only source folder in eclipse?

[atomfrede]

Is the configuration not apt eclipse plugin not sufficient? (Sorry not an eclipse user) https://github.com/tbroyer/gradle-apt-plugin/blob/v0.20/README.md#eclipse

I will try to find some time and check it. I think it would be better to set

eclipse {
  sourceSets {
    main {
      java {
         srcDirs += ["build/generated/source/apt/main"]
      }
    }
  }
}

@jsm174 Which eclipse version are you using? I assume you are using the buildship plugin?

[jsm174]

@atomfrede

Eclipse 4.9.0.v20180906-1121
Buildship 2.2.1v20180125-1441

I modified to srcDirs += and that continues to work.

If you Import an Existing Gradle Project (no build directory), the entry will not be in the Java Build Path. You need to:

1. Gradle Tasks view --> project --> build --> classes
2. Right click on the project and select Refresh
3. Right click on the project and select Gradle -> Refresh Gradle Project

Regardless of above, it's still better than having to manually add the path.
