SMB NIO.2

Maven Central

This is a Java NIO.2 file system provider that can be used to access CIFS/SMB 1.0 and 2.0 file systems. CIFS is the standard file sharing protocol on the Microsoft Windows platform (e.g. to map a network drive).

This library uses jcifs-ng internally, which is an Open Source client library that implements the CIFS/SMB networking protocol in 100% Java.

Dependencies

This library requires the jcifs-ng library as a dependency.

How to use

The easiest way to use the library is to add it as a Maven dependency to your project. Just add the following entry to your pom.xml file.

<dependencies>
  <dependency>
    <groupId>ch.pontius.nio</groupId>
    <artifactId>smb-nio</artifactId>
    <version>0.13.0</version>
  </dependency>
</dependencies>

Once you have added the dependency, you should be able to create SMBPath objects by using the Paths#get(URI) method of the Java NIO.2 library. The URI must be constructed using the 'smb://' scheme. If you want to use credentials, there are several ways to do so. You can either do so directly:

final Path dir = Paths.get(new URI("smb://username:password@host/share/dir1/dir2/"));

Or you can manually create an SMB file system using the following snippet. In this case, the default credentials will always be used.

final Map<String, Object> env = new HashMap<>(); 
env.put("jcifs.smb.client.username", "<username>");
env.put("jcifs.smb.client.password", "<password>"); 
env.put("jcifs.smb.client.domain", "<domain>");

SmbFileSystem fileSystem = SMBFileSystemProvider().newFileSystem(URI.create("smb://host), env);
Path dir = fileSystem.getPath("/dir1", "dir2/");

Last but not least it is also possible to set the aforementioned properties as global system properties when starting the JVM. A complete list of properties supported by jcifs-ng can be found on their GitHub repository.

Important: Please note that paths to directories MUST end with a trailing slash due to requirements of jcifs-ng.
