When I try and create a play project in intelliJ with a java SDK (Using scala) I get the following error after the project is created:

I created a brand new empty Scala Play Framework project with activator new and selecting 6) scala-play. On my fresh install of IntelliJ 64, I am getting this confusing error when trying to open/import the project:

Invalid response.
Does anyone know what could be causing this or what it even means? The play project compiles fine and runs without issues and all the software has been freshly re-installed, so this is likely something specific to IntelliJ.
It appears that erasing the C:\Users\<username>\.sbt folder solved the problem (sbt will recreate it).
As #Roman suggested, this is probably linked to this question, but the suggested solution did not work for me as I didn't even have the .sbt/repositories sub-directory. On the up side, I haven't had any more issues since.
I created a new application using the command
activator new myapp play-java
Then, without modifying anything, I used
activator ui
For opening the admin web console of the new project. Then, I generated the eclipse project of my application from that console. Then I imported the project into a new eclipse workspace and it was good, but when I did run the IntegrationTest class (right click on the file) I got this exception:

Somebody knows how do I fix that?
Thanks a lot !
Most likely caused by Eclipse running sbt to build the workspace concurrently with activator. This thread has an in-depth explanation. Try turning off "Build Automatically" in Eclipse, or instruct it to build to a different directory than target.
I am learning functional programming on Coursera with Scala. To attempt an assignment, I need to start 'sbt' in a project directory. I am following the instructions here: https://class.coursera.org/progfun-004/assignment/view?assignment_id=2
This is the error I got. I am sure that there's a build.sbt file and src folder within the project directory, but somehow sbt fails on me. Any ideas?

try to remove your local ivy directory ~/.ivy2/, you may have some broken jars here. also check your environment variables related to sbt and scala. you can check whether it's your project problem or not by running sbt outside of sbt project, if error still appears, than it's sbt installation or environment problem

Does anybody know how to resolve this issue?
From looking at the code, it seems that it is not possible to resolve HEAD in your repository. I'm not sure how this can happen, but there sems to be something wrong with you Git repository.
I had a similar exception and was able to fix it by creating a branch to avoid detached head state and by committing the pom.xml in that branch.
