How to use shadow jar as main project artifact?

[johnrengelman]

I would suggest creating a new configuration and assigning the output of the shadow task as it's artifact. Then when you declare the project dependency you can specify that you want this configuration instead of the default.

Something like (untested, check the Gradle documentation: http://www.gradle.org/docs/current/userguide/artifact_management.html)

configurations {
   shadow
}

artifacts {
   shadow(tasks.shadow.shadowJar) {
      builtBy tasks.shadow
   }
}

and then in the project dependencies:

dependencies {
   compile project(path: ":myproject", configuration: "shadow")
}

This is exactly what I ended up doing (after a few hours googling). I think it would be useful for others as well to include this in the readme.
thanks

actually here is the correct artifact specification that I used

artifacts {
    shadow(tasks.shadowJar.outputJar) {
        builtBy shadowJar
    }
}

I think the simplest solution is this:

artifacts {
    archives(shadowJar.outputJar) {
        builtBy shadowJar
    }
}

Exactly what's mentioned in the Gradle documentation.

@codesimplicity i think you'll run into an issue with that because the normal jar artifact will be attached to that as well, so you would likely have to set the classifier property on the archive.

artifacts {
  archives(shadowJar.outputJar) {
    classifier 'shadow'
    builtBy shadowJar
  }
}

On my machine, gradle complains that the shadowJar task does not have an outputJar property. Was it renamed?

[johnrengelman]

Yes...ShadowJarTask extends from the Gradle Jar so you would just reference the task the same way you would a Jar task.

I have actually a similar problem and tried the following in build file:

artifacts {
    archives(shadowJar.outputJar) {
        builtBy shadowJar
    }
}

using the most recent version of the plugin I get the following error:

 Could not get unknown property 'outputJar' for task ':shadowJar' of type com.github.jengelman.gradle.plugins.shadow.tasks.ShadowJar.

PS: I'm actually trying to publish the shadowJar alongside the normal JAR.

[johnrengelman]

The code above is 2 years old and since then shadow was refactor to more closely resemble a standard jar task. Please look at the Gradle docs for the Jar task to see th correct property name. Or look at the User Guide which is linked to in the readme for this project. There are ezamoles of configuring publishing in there.

Ok, I did the following:

artifacts {
    archives sourcesJar
    archives javadocJar
    archives shadowJar
}

but now I get the following error:

Could not transfer artifact com.group:name:jar:shadow-classifier:1.0-20160725.192618-22 from/to remote (http://mym2.reop/repository/maven-snapshots): Broken pipe

[johnrengelman]

You're gonna have to dig into it. The examples in the User Guide are part of test cases a verified. Anything beyond that is beyond my control.
If you find a specific issue or are able to create a new, minimal project that exhibits this problem, please open a new ticket.
