After upgrading Gradle, I noticed that performing a release is much slower. This appears to be due to uploadArchives
now including the distribution archives created by the application plugin. Previously the task only uploaded the pom, jars, and asc files. Now the zip and tar archives are included as well.
This appears to have changed with either Gradle 2.4 or 2.5, and does not appear to be intentional going by the release notes.
