Scala Play 2.3.5-Coveralls sbt插件java.io.IOException：无法下载JavaScript

Question

I am currently trying to setup a play scala project buildchain with travis, heroku and coveralls sbt plugin for codecoverage. I have created a clean scala play app with the activator and just added the coveralls plugin and a travis.yml.

When I push my project and trigger the build I get the following exception while travis runs the tests:

[error] c.g.h.h.HtmlPage - Error loading JavaScript from [http://localhost:19001/assets/javascripts/hello.js].
java.io.IOException: Unable to download JavaScript from 'http://localhost:19001/assets/javascripts/hello.js' (status 404).

I have found this old topic ( https://groups.google.com/forum/#!topic/play-framework/yj4NT3BO0Os ) with the same errormessage but unfortunately none of the solutions there worked for me.

Does anyone here use coveralls or know a solution for my problem? I ve attached all configuration files.

Answer 1

The issue is with sbt-scoverage and has been fixed in release 1.0.0. Please note that you have to update the way you use the plugin, so refer to the setup guide on the readme.

The error says you are getting an HTTP 404 (Not Found) error:

java.io.IOException: Unable to download JavaScript from 'http://localhost:19001/assets/javascripts/hello.js' (status 404)

so I'm thinking this isn't so much a problem with your tools but just simply a plain old "not found" issue. Do you have an assets/javascripts/hello.js file in your project?

Answer 3

It seems that this is an issue with the sbt-scoverage plugin and play. I hope that this issue will be resolved in the future...
