Failed to resolve de.measite.minidns: minidns: [0,1,0.2)

I am completely new to Android World. I added SMACK 4.1.0 to develop XMPP capabilities. When trying to create an application, we consistently got errors. Tried searching the internet but no fruitful results. Please help you.

Error: There was a problem configuring project ': app'.

Failed to resolve all dependencies for configuration: app: _debugCompile. Failed to resolve de.measite.minidns: minidns: [0,1,0.2).

Let me know if anything else is required.
