jnr-fuse is a FUSE implementation in java using Java Native Runtime (JNR).

The main goal of the project is to provide an easy way to create a high-performance filesystem in userspace.

FUSE (Filesystem in Userspace) is an OS mechanism for unix-like OS that lets non-privileged users create their own file systems without editing kernel code.

Java Native Runtime (JNR) is high-performance Java API for binding native libraries and native memory.

Prior to0.5.5, jnr-fuse was only available inJCenter. Due tosunsetting of JCenter, starting from0.5.5 is available in maven central.

For implementing your own filesystem you just need to extend FuseStubFS class and implement methods you need.
