Unable to publish produced war file using sbt publish tasks

We have a play 2.1.5 project on which play2-war-plugin 1.1 successfuly builds a war file.

Then when we try to publish the war artifact using standard sbt procedures the war task starts to fail.

Specifically, when we add the following settings:

addArtifact(artifact in war, war)

The war task fails printing the following error:

[error] java.lang.AssertionError: assertion failed: Internal task engine error: nothing running.  This usually indicates a cycle in tasks.
[error]   Calling tasks (internal task engine state):
[error] Task((task-definition-key: ScopedKey(Scope(Select(ProjectRef(file:/trunk/tmp/transferencias/,transferencias)),Global,Global,Global),play-package-everything))) -> Calling
[error] Use 'last' for the full log.

Remarkably that error is cited as the reason to exclude the mentioned settings from play2-war-plugin default settings in Play2WarSettings.play2warSettings.

A workaround is to keep the war and the publish separated:

val packageWar = taskKey[File]("package-war")

packageWar := {
    val warFile = name.value + "-" + version.value + ".war"
    (baseDirectory in Compile).value / "target" / warFile
}

// create an Artifact for publishing the .war file
artifact in (Compile, packageWar) := {
  val previous: Artifact = (artifact in (Compile, packageWar)).value
  previous.copy(`type` = "war", extension = "war", classifier = Some("webapp"))
}

// add the .war file to what gets published
addArtifact(artifact in (Compile, packageWar), packageWar)

With that configuration, your must first generate the war and then call publish.

Hii,

I want to publish sbt zip file to nexus repository. Using versions (play -2.4.2 & sbt 0.13.6). I have tried above workaround for zip file publish. Its giving me authorization errors where everything is well set and working for another projects(for jar publish). I follow the steps below: 1 sbt compile -> Compile project 2 ./activator dist command -> creates .zip folder in target>universal dir of sbt project 3/ sbt publish -> used above workaround

Could you please post the workaound for sbt (target>universal> .zip file) publish ?
