Compile scala project with gradle: MissingRequirementError

Question

I have a project that used SBT before, I'm trying to compile it using gradle with scala plugin, but have got an exception as below:

[ant:scalac] scala.reflect.internal.MissingRequirementError: object java.lang.Object in compiler mirror not found.

According to internet it's an issue with scala/zinc version incompatibility. This project has scala 2.11 dependencies (and been built with scala library 2.11 before), so I've tried to add explicitly proper scala and zinc versions to dependencies (in various combinations), but results are the same.

dependencies {
    zinc 'com.typesafe.zinc:zinc:0.3.9'
    compile 'org.scala-lang:scala-library:2.11.6'

Any suggestions?

I've seen that topic. How to translate it into gradle? I though adding scala-library is what they suggest. — vvg, Dec 29 '16 at 11:15
Please post all build files to help us investigate this further. — Christian Neverdal, Dec 29 '16 at 16:27

There was another error message, which I missed initially:

[ant:scalac] error: error while loading <root>, Error accessing ... activation\1.0.2\48d628027388ba84af265623c1434a70
bffdc175\activation-1.0.2.jar

Excluding this artifact from build resolved the issue:

    exclude group: 'activation', module: 'activation'
