Integration with Apache Mina not working

[rashmimaharana]

Hi @carlspring

Bug Description

I have been trying to integrate this file system with Apache Mina sshd 2.12.1. But its failing. Here is the code snippet that I configured. If I pass the bucket name as plain with out any / , its throwing error as this.fileStore is null and when i passed the bucket with /mybucket/, it's connecting but giving error as below. I am using org.carlspring.cloud.aws:s3fs-nio:1.0.5.

Steps To Reproduce

1. Setup Apache Mina sshd server with version 2.12.1.
2. Integrate with org.carlspring.cloud.aws:s3fs-nio:1.0.5.
3. Create a FileSystemFactory like below and integrate with Apache Mina 2.12.1.

   
   sshd.setFileSystemFactory(createFileSystemFactory("mybucket"));

public FileSystemFactory createFileSystemFactory(String bucketName) throws IOException { Map<String, ?> env = ImmutableMap.<String, Object>builder().put(ACCESS_KEY, "AKIAX*") .put(SECRET_KEY, "hnBpn**") .put(REGION,"us-east-1") .build(); FileSystem fileSystem = FileSystems.newFileSystem(URI.create("s3:///"), env, Thread.currentThread() .getContextClassLoader()); Path bucketPath = fileSystem.getPath(bucketName); return new VirtualFileSystemFactory(bucketPath); }

# Expected Behavior

Should be able to connect to s3 bucket and list files

# Environment

* `s3fs-nio` version: s3fs-nio:1.0,5

Hi @rashmimaharana @SergiyBojko,

Your bug reports seems to be related.

Would you guys be able to provide JUnit test cases for them? Perhaps something with TestContainers?

We would be really happy to receive pull requests with fixes for this as we have limited resources at the moment.

@rashmimaharana We haven't had a chance to look into this yet. Can you try the code you have with the 1.0.6-SNAPSHOT version which is published in Maven Central Snapshots? There was a bug related to the properties not being passed from the Files.newFileSystem down to the S3FileSystem which could have been related to the problem you are seeing.
