Re: Connect error: SASL Authentication failed. No known authentication mechanisims

You only need to include the smack-java7 dependencies. This includes all other dependencies.

Maven example..

<dependency>

  <groupId>org.igniterealtime.smack</groupId>

  <artifactId>smack-java7</artifactId>

  <version>4.1.0</version>

</dependency>

Hope this helps
