"Error: Could not find or load main class Start" This is the error I have been dealing with for the past few days, no matter how much research I do it doesn't seem ot help me at all.
I know that it is trying to locate "Start.java", I believe I have configured Eclipse to look for Start.java in the (default packages) package, where it is. However, I click the run button and the error just keeps popping up. Please, I desperately need help, any comment will be appreciated greatly.
[Update] I managed to add Start.class to my classpath somehow, I just tried every single method on StackExchange and one of them seemed to work. However, yet another problem has arose, on launch this occurs:
Exception in thread "main" java.lang.SecurityException: class "bgv"'s signer information does not match signer information of other classes in the same package at java.lang.ClassLoader.checkCerts(Unknown Source) at java.lang.ClassLoader.preDefineClass(Unknown Source) 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 Start.main(Start.java:11)
Start.java, which is source code. It's trying to findStart.class, which is the compiled bytecode. - Jon Skeet
