I have a workaround I found in another post.
Exit forge, edit ~/.forge/addons/installed.xml , remove the line of your addon
remove the directory of your addon in ~/.forge/addons/
Also, be sure to use the same version of Forge in shell & ide
Thanku i will surely try this one.
My alternate when I test the result in Eclipse is to increase the version number before each build.
Dirts the ~/.addons folder but avoid to restart Eclipse (File / restart) to remove lock on the addon's jar
