Production mode not working

[thibaultmeyer]

Hi

I use sbt uglify 1.0.3 on Java Play 2.4.3.

Everything is working on activator run but the pipeline crash with activator stage or activator dist.

It appear that plugin create a folder application.js.min rather than a file .

I've created a topic about this issue : https://groups.google.com/forum/#!topic/play-framework/11Wi5QEV5FU

build.sbt

UglifyKeys.uglifyOps := { js =>
  Seq((js.sortBy(_._2), "application.min.js"))
}

UglifyKeys.uglifyOps in Assets := { js =>
  Seq((js.sortBy(_._2), "application.min.js"))
}

pipelineStages := Seq(uglify)

pipelineStages in Assets := Seq(uglify)

Output

@0xBAADF00D FYI, I encountered the exact same issue. For anyone else that might wander in those corners, my workaround was:

pipelineStages := Seq(digest, gzip)
pipelineStages in Assets := Seq(uglify)

Yes, the downsides include the fact it runs uglification in dev, although uglify without rjs is quick enough, and all scripts are minified - but source maps are included so debugging shouldn't be too much of a hassle.

On the other hand, it actually generates *.min.js files as intended, unlike the production mode, and should allow you to do sbt clean compile stage until a real fix comes along.

Hi,

thanks for this workaround. It working.

[pcwiek]

@0xBAADF00D Honestly, I wouldn't close the issue, since it's a workaround, not a solution. Underlying problem is still there - stage should generate files, not directories.

[thibaultmeyer]

oh, ok I re-open issue

Can confirm that production mode is not working for latest sbt-uglify 1.0.4 running on Play 2.6.
After running ./sbt stage non-minified javascripts are included.
