Gradle is slow to build IDEA project files

Help/Discuss
1

When trying to rebuild the IDEA project files for a largish project, the build seems quite slow (almost as slow as a complete rebuild of the whole project). Running Gradle with info enabled it seems to be hitting the artifactory server over and over for the same jar file. I’m sort of wondering if there is something funny with that jar which makes it problematic?

gradle --info cleanIdea idea

Any pointers would be appreciated! We’re using Gradle 2.8.
