sbt compilation causes stackoverflow error

Question

I have been facing this error for sometime now. Totally irritated because of this. Tried all the similar solutions seen in stackoverflow and other sites.

I have a 4 separate scala projects. Out of those, I am getting StackOverflow error on compilation of tow projects. These two projects are the biggest ones out of the 4 projects. I am getting this error when I try to build the project in Ubuntu Server machine. I tried increasing the Xmx options in sbt config file, but with no success.

Can anyone please help me to solve this, as I am going mad because of this. If I build the project 10 times, it will get succeeded in 1 or 2 attempts.

What I understood from the error log is that the issue comes with type checking. But, I have no idea where that occurs.

One of the failing projects have over 1000 classes/traits (without including case classes).

Details:

Ubuntu Server(14)
Sbt : 0.13.6 and 0.13.8 tried
Scala Version : 2.11.6
JDK: 1.8

A few lines of the error is pasted below:

Answer 1

I tried all the configuration changes, but didn't work in the machine. So I had skipped this for almost a month. Recently, I tried building the project in Jenkins and was getting the same error. Then I upgraded sbt 0.13.8 and added the jvm flag -XX:+CMSClassUnloadingEnabled -XX:MaxPermSize=256m -Xmx1024M -Xss16M to the jenkins build flag. And so far, all the compilations have been successful. I remember adding the jvm flag to sbt config file, but was getting the same error. But now, it is working fine in jenkins after adding that flag.

Answer 2

This has been affecting Scala since 2.11.4 till 2.11.6 afaik. It doesn't appears as fixed on the latest release notes for 2.11.7.

Fortunately following the track on the issue tracker it's a duplicated ticket with an answer here on stack overflow

Without the source code is harder to give more indications but that should definitely be a good pointer to find the issue and apply the proposed solution
