I'm getting this: # ./plugin Exception in thread "main" java.lang.NoClassDefFoundError: /opt/ elasticsearch/lib/jline-0/9/94/jar Caused by: java.lang.ClassNotFoundException: .opt.elasticsearch.lib.jline-0.9.94.jar at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java: 301) at java.lang.ClassLoader.loadClass(ClassLoader.java:247) Could not find the main class: /opt/elasticsearch/lib/ jline-0.9.94.jar. Program will exit. The only other result in the mailing list similar to this said to add CDPATH="" to the script, but it's there now in 0.18.3 Any thoughts? ---

Use 0.18.4, there was a bug in the plugin script in 0.18.3.

Ok, is there a guide to upgrading somewhere? Can I just replace the elasticsearch.jar file in the lib directory and restart?

In general, when you upgrade, you can simply unpack the new version, point the data location to the new one, and update relevant configs. In this case, you can simply replace the plugin file, which is the only change between 0.18.3 and 0.18.4, but I suggest using the "official" 0.18.4 version to remove confusion.
