The pure java implementation of NFS server version 3, 4.0 and 4.1 including pNFS extension with nfs4.1-files and flex-files layout types.
To build nfs4j from source code Java11 and Maven3 are required.
To run benchmarks:
mvn verify -Pbenchmarkpublic class App { public static void main(String[] args) throws Exception { // create an instance of a filesystem to be exported VirtualFileSystem vfs = new ....; // create the RPC service which will handle NFS requests OncRpcSvc nfsSvc = new OncRpcSvcBuilder() .withPort(2049) .withTCP() .withAutoPublish() .withWorkerThreadIoStrategy() .build(); // specify file with export entries ExportFile exportFile = new ExportFile(....); // create NFS v4.1 server NFSServerV41 nfs4 = new NFSServerV41.Builder() .withExportFile(exportFile) .withVfs(vfs) .withOperationFactory(new MDSOperationFactory()) .build(); // create NFS v3 and mountd servers NfsServerV3 nfs3 = new NfsServerV3(exportFile, vfs); MountServer mountd = new MountServer(exportFile, vfs); // register NFS servers at portmap service nfsSvc.register(new OncRpcProgram(100003, 4), nfs4); nfsSvc.register(new OncRpcProgram(100003, 3), nfs3); nfsSvc.register(new OncRpcProgram(100005, 3), mountd); // start RPC service nfsSvc.start(); System.in.read(); } }<dependency> <groupId>org.dcache</groupId> <artifactId>nfs4j-core</artifactId> <version>0.19.0</version> </dependency> <repositories> <repository> <id>dcache-releases</id> <name>dCache.ORG maven repository</name> <url>https://download.dcache.org/nexus/repository/public/</url> <layout>default</layout> </repository> </repositories>Though NFS4J is used by the dCache and other projects in production, the public API is still unstable and subject to change (indicated by leading zero in the version number). Thus, should be considered as beta.
Please consult the API changes document when switching between version numbers. The patch level releases are not affected by API changes, of course.

NFS4J uses the linux kernel model where git is not only source repository, but also the way to track contributions and copyrights.
Each submitted patch must have a "Signed-off-by" line. Patches without this line will not be accepted.
The sign-off is a simple line at the end of the explanation for the patch, which certifies that you wrote it or otherwise have the right to pass it on as an open-source patch. The rules are pretty simple: if you can certify the below:
Developer's Certificate of Origin 1.1 By making a contribution to this project, I certify that: (a) The contribution was created in whole or in part by me and I have the right to submit it under the open source license indicated in the file; or (b) The contribution is based upon previous work that, to the best of my knowledge, is covered under an appropriate open source license and I have the right under that license to submit that work with modifications, whether created in whole or in part by me, under the same open source license (unless I am permitted to submit under a different license), as indicated in the file; or (c) The contribution was provided directly to me by some other person who certified (a), (b) or (c) and I have not modified it. (d) I understand and agree that this project and the contribution are public and that a record of the contribution (including all personal information I submit with it, including my sign-off) is maintained indefinitely and may be redistributed consistent with this project or the open source license(s) involved.then you just add a line saying ( git commit -s )
