Google Plugin for Eclipse – jar has been tampered!
Problem
While installing Google Plugin for Eclipse 3.7, via http://dl.google.com/eclipse/plugin/3.7 , it took almost half and hour and download and stopped at the end.
A long list of error messages “.jar has been tampered!” are prompted in Eclipse.

Solution
From this thread, the JDK/JRE 7 will caused the Google plugin for Eclipse failed to download.
To solve it, change the Eclipse’s JRE back to more stable version, like JRE 6.
