I’ve noticed sometimes I get a bunch of script directories in a directory named MM/caches/1.9/scripts/ in my project root. This doesn’t occur during a normal clean build cycle but this interferes with my source control, etc. I’m not sure if this is something new or misplaced but maybe only occurs on initial builds or gradle version switching, and I also notice directories for each applied build script, so I’m sure it must be gradle doing this?
Currently using gradle 1.9

Have no idea what MM is. Our project root is called Momentum and MM appears inside. There might be one complication. My current setup is that I checkout source code on my host, build a Vagrant VM and synchronise ~/.gradle caches and .m2 repos between the VM and the host, so that I can build in and outside of the VM at the same time, editing in Eclipse in the host and running servers in the VM. This has been going fine since about 1.6, but I’m sure I’ve only noticed this since 1.9 because the source code syncronisation never picked it up before, now suddenly I have loads of extra files that appear. So it could be something within all this switching but there is definitely nothing explicitly called MM that I know of anywhere. Other than what’s shown below there is no explicit setting of Gradle user home either. I’ll just have to watch under what conditions it occurs again if this has not been seen before. Thanks

I don’t think that ‘MM’ is a name chosen by Gradle. Transferring the Gradle cache between machines is not supported and may not work correctly. I sugeest to keep the caches separate. The local Maven repository should only be used in cases where a Gradle build needs to consume the output of a Maven build (or the other way around). Otherwise, don’t declare ‘mavenLocal()’, and don’t sync ‘.m2’.
We are running 3 or 4 projects all talking to each other via the .m2 repo - no problem or at least testing plugin updates installed into .m2 then used in the other projects. So that bit works fine without issues.
It doesn’t stop us - because we can just delete the MM directory and carry on when it appears. Its only rarely there so not a show stopper.
I understand its not supported thanks but will keep you posted if I can detect when it happens.
I finally figured this out. I use a lot of -x exclusions when running a task repeatedly that has lots of dependencies to reduce the time. In this case I used the abbreviation of a task gMM and sometimes mistype ‘-x gMM’ as ‘-gMM’. This results in a new local gradle cache in the MM directory. I noticed whenever I mistype it starts downloading all the dependencies which gave a clue! Mystery solved
