Old Gradle Tooling dependency cannot be found

Affected version is 3.2.1, but it's not available for selection.

The resolver uses an old version of the Gradle tooling - 4.0.1 (https://github.com/shrinkwrap/resolver/blob/56db3900d4e6b035a1efa42d4ae1ddd69f2db6df/pom.xml#L38) that isn't in the maven repo anymore (https://mvnrepository.com/artifact/org.gradle/gradle-tooling-api?repo=gradle-libs-releases-local).

When executing `test`, Gradle complains:
> Could not find org.gradle:gradle-tooling-api:4.0.1.

Searched in the following locations:

- https://repo.maven.apache.org/maven2/org/gradle/gradle-tooling-api/4.0.1/gradle-tooling-api-4.0.1.pom

Required by:

project :GameServer > org.jboss.shrinkwrap.resolver:shrinkwrap-resolver-gradle-depchain:3.2.1 > org.jboss.shrinkwrap.resolver:shrinkwrap-resolver-impl-gradle-embedded-archive:3.2.1

Maybe the tooling needs to be updated to a recent version like 7.4.2.
