Hello, I'm developing a plugin for ArgoUML (Macmas). My project runs fine with Eclipse 3.2, but when I create the plugin jar file and I launch it with build\argouml.bat, the following message appears:
java.lang.Security exception: class "org.argouml.ui.MacmasModule"'s signer information does not match signer information of other classes in the same package I have read that it can be a duplicate jars problem, but I don't find duplicate jars at build directory
