Can't fetch C# grammar with the .launch file

[rcjsuen]

My C# editor wouldn't open because the grammar file couldn't be found so I tried to use Fetch Grammar.launch to fetch it but the launch configuration didn't complete.

Unfortunately, I couldn't figure out a way to rerun with -e or -X like the error message suggested. My org.eclipse.acute project has no compiler errors so I feel like my target platform is okay.

I do have two errors in my 'Problems' view but I'm not sure if they're relevant or not.

I worked around the problem by downloading the csharp.tmLanguage file myself and throwing it in the org.eclipse.acute/grammar/ folder.

The Launch Config should be updated to run from the root folder so TP content is accessible.

The .launch file was refactored to cover all deps at once, and simply runs a mvn clean verify -DskipTests -Djgit.dirtyWorkingTree=warning
