Hi, Hope you can help! I am not able to startup the ES in the terminal. Previously installed ES and was working fine. However, it cannot start up now. Here's the error returned: Stephanies-MacBook-Pro:elasticsearch stephanielew$ bin/elasticsearch -f Exception in thread "main" java.lang.NoClassDefFoundError: Could not initialize class org.elasticsearch.Version at org.elasticsearch.bootstrap.Bootstrap.buildErrorMessage(Bootstrap.java:252) at org.elasticsearch.bootstrap.Bootstrap.main(Bootstrap.java:236) at org.elasticsearch.bootstrap.ElasticSearch.main(ElasticSearch.java:32) - Am using MacBook OS Version 10.8.5. - Java Version 1.6.0\_65 Previous actions: - Was using ES Java Api in Maven web project in Netbeans. It was able to connect to ES server automatically via Apache Tomcat when the web application was run. However, after installing some external jars the ES server did not start up. - Also, tried to run ES in the terminal separately, but it still could not start up. Despite several attempts to delete some old directories and installing the latest version, the above error was returned. Is there some permanent system/environment variables that should be changed in my computer configurations? Or how can i cleanly remove all elasticsearch related folders? Any uninstall command? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Sounds like you're trying to start it from the cloned git repo, rather than first building it. See the README for details of how to build it clint On 18 October 2013 12:33, Stephanie Lew [steph.lewyh@gmail.com](mailto:steph.lewyh@gmail.com) wrote: > Hi, > > Hope you can help! > > I am not able to startup the ES in the terminal.
