Supported versions

Spock is supported for Java version 6, 7, and 8. Spock is supported for Groovy version 2.0 (Not supported for Java 8+), 2.3, 2.4

The tests are testing spock with a specific versions (variants) of groovy. Default is groovy version 2.4

The groovy 2.4 variant should pass on all supported JDK versions:

./gradlew clean build

(Windows: gradlew clean build). All build dependencies, including the build tool itself, will be downloaded automatically (unless already present).

If you are using JDK 6 or 7 you can specify groovy version 2.0 with using -Dvariant=2.0 and it should pass as well:

./gradlew clean build -Dvariant=2.0
