Please help me to resolve this issue 

Answer 1

Select the Xtend SDK from the category Xtend {version} and complete the wizard by clicking the Next button until you can click Finish.

If you have selected multiple items, first deselect all . Then choose the lastest Xtend-2.6.1 version. Worked for me.
