.NoClassDefFoundError while working with AndroidSDK jar file in IntelliJ

Issue

I was trying to call one of the method in Android library of uiautomatorviewer located at C:\Users\krrishna\AppData\Local\Android\sdk\tools\lib\uiautomatorviewer.jar. I tried this library by adding it from IntelliJ -> Project Right Click -> open module settings -> jars directories -> finish

The device object here is the IDevice returned from the library and i get the correct number of devices when i called AndroidDebugBridge.getDevices().

 device.getHierarchyViewer().getFocusedWindowName();
