I really like the ease of updating Gradle:
gradlew wrapper --gradle-version X.Y will get me from one version of Gradle to the the next. I never have to bother installing and managing an actual Gradle installation myself.
Except for bootstrapping a project. In this case I have to download the large zip file, extract it, set up my PATH etc. just to initialize a wrapper for my project, which will download its own Gradle distribution yet again.
It would be great if I could just download the tiny wrapper as a zip file (containing the two scripts, a jar and a properties file), extract this into my project dir and be ready to go.
What do you think?
