Gradle build results in jar missing shadowed antlr4-runtime classes #3790

Hello folks,

I'm new to building with gradle, and I've noticed that when I build v22.0 using a simple ./gradlew clean build command, the built jar at build/libs/graphql-java-0.0.0-HEAD-SNAPSHOT.jar is missing the shadowed antlr4-runtime classes, which causesjava.lang.NoClassDefFoundError when its used as a dependency. Is there a correct way to build the jar? Thanks.

Hello, this is what we use to publish the jar, could you give this a try? https://github.com/graphql-java/graphql-java/blob/master/.github/workflows/master.yml

Hi, thanks for the reply. I have noticed the workflow and tried the ./gradlew publishToSonatype but I can't publish the jar, so the build fails with:

A problem was found with the configuration of task ':publishGraphqlJavaPublicationToSonatypeRepository' (type 'PublishToMavenRepository').
  - In plugin 'org.gradle.api.publish.maven.plugins.MavenPublishPlugin$Inject' type 'org.gradle.api.publish.maven.tasks.PublishToMavenRepository' property 'credentials.username' doesn't have a configured value.

Is there a way to run the same build, with shadowJar but without the publish step? How do you folks build the jar locally for e.g. development or testing?

I remember now, we came up against the same problem before!

For convenience we changed the config so the publishToMavenLocal task which will skip the signing parts that generated the error. Try giving that a go, it should publish the jar to your local m2 repository, and not complain about the missing credentials.

signing {
    required { !project.hasProperty('publishToMavenLocal') }
    def signingKey = System.env.MAVEN_CENTRAL_PGP_KEY
    useInMemoryPgpKeys(signingKey, "")
    sign publishing.publications
}
