Spring Boot Gradle plugin >= v2.5.0 outputs both executable fat jar and plain jar, and GAE Gradle plugin uses plain one.

This is not a bug, but a feature request. Spring Boot Gradle plugin in the current version generates both executable fat jar and plain jar in the default settings like build/libs/aaa-0.0.1.jar build/libs/aaa-0.0.1-plain.jar , and when I run ./gradlew appengineShowConfiguration, it shows stage artifact is plain one.

My feature request is that GAE plugin will use fat one automatically without specifying artifact or disabling generating plain one.

more friendly one:

appengine {
    stage {
        artifact = bootJar.archiveFile.get()
    }
}

You can set appengine.stage.artifact to specify a deploy artifact:

appengine.stage.artifact = 'build/libs/demo-0.0.1-SNAPSHOT.jar'

I’m afraid this feature request is a very low priority for us. We accept contributions though.
