To be honest, on the installation method, Eclipse's plug-in installation should be the easiest in the world. However, many people find that the installed plugins are not effective. This problem has also plagued me for a long time. When I installed CDT, I found the failure when I installed the CV Dafa, and the online upgrade of the next use was successful! But when I installed VEP, CV Dafa and online upgrade did not care, I always said that EMF1.0 needs the reminder of EMF2.0.1 when I upgrade, but I am clearly recognized in the plugin, I really don't know Yes, there is something wrong! This problem makes me depressed and long, I finally found a lot of people in a blog and I have the same experience, and the solution is so Easy! --- Delete the Configuration directory under the Eclipse directory and restart it! I fell!
