how to add config file in scala-eclipse

[Bill Turner]

This should be a no-brainer, but... I have what I believe to be the latest Scala-eclipse - I downloaded it just before the start of the Coursera class FP in Scala began a few weeks ago. I recently installed the scala-style plugin. Then, downloaded the config file to my workspace. When I go to preferences, I do not see the file. I have tried selecting "add" and it still does not show up. I moved the config into a project, navigated into the project and it still does not show. What am I missing?

So, the scala-ide site states the following:

After installing the plugin one needs to add the Scalastyle configuration of the Scala IDE. This can easily be done in Window → Preferences → Scalastyle → Browse/Add, where the configuration can be found at <path-to-scala-ide>/org.scala-ide.sdt.core/scala-ide-style-config.xml. The Scalastyle builder is already added to all projects that should be checked, thus no further configuration is required.

However, since the page I am referencing is about the scala-ide plugin, perhaps there is not such path as <path-to-scala-ide>/org.scala-ide.sdt.core/. At least not that I can find (I installed scala-eclipse, not the plugin). Still, my question remains, why doesn't the "add" feature work? Should I create new and copy and paste the downloaded scala-style-config? This seems to force me to create one in each project, not a global config. It is not very DRY to have multiple copies of the config, one for each project, when they would all be the same.

Did you add the scalastyle-config.xml into your project? If so, you may need to refresh the project - Select the project in the project/package explorer and press F5 ( or Refresh when you right click). Then the file should appear as an option in the Windows -> Preferences.

Once you've added the file in WIndows -> Preferences, go to the project properties (Right click on the project, select Properties) and make sure the scalastyle settings are correct there. Then at the next compile, you should start getting errors.

Thanks.
