> I detected this when I was trying to put my build dir to ramdisk. I have
> plenty of RAM available on my workstation (64GB) and I was thinking about
> moving "build" dir to ramdisk so I could make it faster a little bit and also
> spare some write cycles to ssd. It can look like irrelevant improvement but I
> think that if devs are building the project repeatedly times and times again,
> this can easily add up.
> {code:java}
> mkdir /tmp/cassandra
> # in /etc/fstab
> tmpfs /tmp/cassandra tmpfs defaults,noatime,size=2048M,x-gvfs-show,mode=1777
> 0 0
> # then sudo mount -a
> # I have worktree setup so the build for each branch will end up in different
> dir:
> # mkdir -p
> /tmp/cassandra/{trunk,cassandra-4.1,cassandra-4.0,cassandra-3.11,cassandra-3.0}
> {code}
> Then in build.properties for each respective branch:
> {code:java}
> ant.gen-doc.skip: true
> build.dir: /tmp/cassandra/trunk/build
> build.dir.lib: /tmp/cassandra/trunk/build/lib
> {code}
> The problem with this is that it fails on rat, because there is not
> "build.dir" property used, it is hardcoded to "build" but there is not
> anything to rat on so it will hang.
