Hi! Which maven dependencies does your plugin have? I've seen this happening when something pulls in a different version of asm, one of the interfaces has changed into a abstract class, leading to this error. we had to exclude it at some point.
Is your plugin open source? If so I could take a look. cheers, -k On Monday, February 24, 2014 3:17:42 PM UTC+1, Craig Blake wrote: > > Forgot to mention that I'm running the 0.20.0 release of the server. > > On Monday, February 24, 2014 9:17:16 AM UTC-5, Craig Blake wrote: >> >> Hi, I've put together a test plugin using the 020 branch of >> graylog2-plugin-interfaces but I'm getting an error at startup time in the >> server: >> >> Exception in thread "main" java.lang.IncompatibleClassChangeError: >> Implementing class >> at java.lang.ClassLoader.defineClass1(Native Method) >> at java.lang.ClassLoader.defineClass(ClassLoader.java:791) >> at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142) >> at java.net.URLClassLoader.defineClass(URLClassLoader.java:449) >> at java.net.URLClassLoader.access$100(URLClassLoader.java:71) >> at java.net.URLClassLoader$1.run(URLClassLoader.java:361) >> at java.net.URLClassLoader$1.run(URLClassLoader.java:355) >> at java.security.AccessController.doPrivileged(Native Method) >> at java.net.URLClassLoader.findClass(URLClassLoader.java:354) >> at java.lang.ClassLoader.loadClass(ClassLoader.java:423) >> at java.net.FactoryURLClassLoader.loadClass(URLClassLoader.java:789) >> at java.lang.ClassLoader.loadClass(ClassLoader.java:356) >> at java.lang.Class.forName0(Native Method) >> at java.lang.Class.forName(Class.java:266) >> at org.graylog2.plugins.PluginLoader.getPlugins(PluginLoader.java:61) >> at org.graylog2.Core.registerPlugins(Core.java:434) >> at org.graylog2.Core.run(Core.java:292) >> at org.graylog2.Main.main(Main.java:266) >> >> Normally I would expect that message to indicate the offending class, but >> for some reason it's empty here.
