Question

I have been using sshj libraries

<dependency>
    <groupId>net.schmizz</groupId>
    <artifactId>sshj</artifactId>
    <version>0.3.1</version>
</dependency>

Following was my code using 0.3.1 which worked fine for doing uploading of files supporting wildcard patterns.

SSHClient client = null;
SCPUploadClient uploader = null;
try {
    client = getClient();
    uploader = client.newSCPFileTransfer().newSCPUploadClient();
    uploader.setFileFilter(new WildcardFileFilter(wildCardPattern));

    //determine the remote directory
    File f = new File(localDirLocation);
    String dir = remoteDirLocation + f.getName();
    uploader.copy(localDirLocation, remoteDirLocation);
} catch (IOException e) {
      //processing exceptions here
} finally {
    disconnectClient(client);
}

But now the code gives me a lot of compilation errors when I tried moving over to 0.5.0.

I would like to understand how do I go about setting fileFilters when I want to do uploading and downloading of files from local to remote machine and vice versa

Can someone please help me with this ?

Using 0.6.0 you can write your code as follows:

SSHClient client = null;
SCPUploadClient uploader = null;
try {
    client = getClient();
    uploader = client.newSCPFileTransfer().newSCPUploadClient();
    uploader.setUploadFilter(new WildcardFileFilter(wildCardPattern));

    //determine the remote directory
    File f = new File(localDirLocation);
    String dir = remoteDirLocation + f.getName();
    uploader.copy(new FileSystemFile(localDirLocation), remoteDirLocation);
} catch (IOException e) {
    //processing exceptions here
} finally {
    disconnectClient(client);
}

The WildcardFileFilter you used came from commons-io I guess. As that is a FilenameFilter and not a LocalFileFilter, you could very simply implement this as:

public WildcardFileFilter implements LocalFileFilter {
    private String wildcardPattern;

    public WildcardFileFilter(String wildcardPattern) {
        this.wildcardPattern = wildcardPattern;
    }

    @Override
    public boolean accept(LocalSourceFile file) {
        return FilenameUtils.wildcardMatchOnSystem(file.getName(), wildcardPattern);
    }
}
