Activator 1.3.6 rewrite build.sbt

Question

Twice, Activator (or something) rewrote my build.sbt for the Play 2.4.4 project. After editing the view file, I refreshed the page in my application to refresh everything in Eclipse. It did not work as expected, so I restarted the activator. After reopening the project, he simply got stuck on the “Building Project” after compilation. After some searching, it turns out that build.sbt empty, except for one line:

 fork in run := true 

From this question, I understand that Activator looks for this line and sometimes adds it, but why does it overwrite the entire file?

Update:

This continues with Activator 1.3.10 and happened in every version of Activator that I used with 1.3.6.

Answer 1

Unless you have a specific reason, use SBT instead of an activator. The activator is just a shell with a web interface for the sbt project.
