问题
I'm looking around in my ~/.gradle folder (relocated to P:\caches\gradle, which doesn't affect this behaviour) and I found some strange folders.
In the past I have updated multiple projects from 2.0 to 2.1 via running gradle wrapper which updated project\gradle\wrapper\gradle-wrapper.properties
I just found out that for some reason the exact same distributionUrl zip file was downloaded multiple times. As you can see they all have the same size and I did a binary diff, they're the same bit by bit except the timestamps:
The contents of each folder above look like this:
I just updated from 2.2 to 2.2.1 and it happened again: this time it's 2 folders not 3. Does anyone know why this happens?
I'm using Gradle from both IntelliJ Idea and the command line.
