Gradle 2.2.1 fails building C++ project

Trying out Gradle for a C/C++ project. It works without any problems with Gradle 2.1, but not with Gradle 2.2.1

Trying to build with Gradle 2.2.1 :compileCpptestSharedLibraryCpptestC FAILED

FAILURE: Build failed with an exception.

  • What went wrong: Execution failed for task ‘:compileCpptestSharedLibraryCpptestC’. > Could not find C compiler ‘gcc’ in system path.

This is my build.gradle script:

apply plugin: 'c'
apply plugin: 'cpp'
  model {
    platforms {
        x86 {
            architecture "x86"
        }
        x64 {
            architecture "x86_64"
        }
    }
    toolChains {
        gcc(Gcc) {}
        clang(Clang) {}
    }
}
  libraries {
    myLibC {}
    myLibCpp {}
    plugins {}
}
