I have a VM with an NFS-mounted file system and a PhpStorm project in a directory on that file system. The project is set up to treat the files as "in-place" rather than a remote mounted NFS share with a deployment step. The problem is that whenever files are updated on the NFS system, for instance, when I execute a git pull, the changes are not reflected in PhpStorm until I explicitly right click on a directory and click "Synchronize". But there is virtually no latency when writing files from PhpStorm to the NFS system — that works just fine.
These are the settings I use to mount the NFS share, which I've tinkered with to no avail:
/mnt/nfs/home -fstype=nfs,rw,sync,resvport,insecure nfs://192.168.88.88:/home/devadmin
The guest VM is CentOS and VMware Fusion is the provider. I'm running PhpStorm 10.0.3 on Mac OS X 10.10.5.
