“Ok finally i find the solution for solve this problem i don't know why Eclipse showing me this error and i don't know is this a best solution but anyway i solve my problem with delete the artifacts.xml file in Eclipse root directory After delete this file try to install that plugin again but this time after few second everything done and work perfectly
UPDATE: If you get that's error again just go to Eclipse root directory and search for "artifacts.xml" and delete all the files is in the result ;)”
