Posted November 29, 201212 yr Hello! I have a problem with 6.4.x versions of Forge. When I try to install it to the SMP (either extracting into minecraft_server.jar or running minecraftforge.jar) I recieve error: Exception in thread "main" java.lang.IncompatibleClassChangeError: Implementing class at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(Unknown Source) at java.security.SecureClassLoader.defineClass(Unknown Source) at java.net.URLClassLoader.defineClass(Unknown Source) at java.net.URLClassLoader.access$100(Unknown Source) at java.net.URLClassLoader$1.run(Unknown Source) at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.launcher.LauncherHelper.checkAndLoadMain(Unknown Source) Tried multiple versions of Forge, looked through forum, did not found the solve. Please, help me. The Mary Sue is not defined by her power, but by her lack of an even more powerful opponent. ©LessWrong
November 29, 201212 yr What version of your server do you have? Also did you delete the files with MOJANG in their filename inside the META-INF folder after installing Forge? Don't ask for support per PM! They'll get ignored! | If a post helped you, click the "Thank You" button at the top right corner of said post! | mah twitter This thread makes me sad because people just post copy-paste-ready code when it's obvious that the OP has little to no programming experience. This is not how learning works.
November 30, 201212 yr Ensure that you are running server for 1.4.5. Read the EAQ before posting! OR ELSE! This isn't building better software, its trying to grab a place in the commit list of a highly visible github project. www.forgeessentials.com Don't PM me, I don't check this account unless I have to.
