Checkstyle plugin dependencies versions

Hi,

our internal Nexus scanned the project and found a security issue regarding commons-bean-utils version 1.9.3. I ran Gradle dependencies and found out that this dependency is a transitive dependency of the check style plugin.

In the build.gradle we add the plugin via apply plugin: 'findbugs'. No version or anything. So how do I find out which version is used? And how do I upgrade?

Thanks
