Java no class def found error elasticsearch?

Question

I followed these steps on https://github.com/karmi/tire to install elasticsearch for use with ruby on rails curl -k -L -o elasticsearch-0.17.6.tar.gz http://github.com/downloads/elasticsearch/elasticsearch/elasticsearch-0.17.6.tar.gz tar -zxvf elasticsearch-0.17.6.tar.gz ./elasticsearch-0.17.6/bin/elasticsearch -f I am running this on MinGW on windows 7, and most of the process went smoothly. However, as I try to start the server with ./elasticsearch-0.17.6/bin/ elasticsearch -f I get a java no class def found error: $ ./elasticsearch-0.17.6/bin/elasticsearch Exception in thread "main" java.lang.NoClassDefFoundError: org/ elasticsearch/bootstrap/ElasticSearch Caused by: java.lang.ClassNotFoundException: org.elasticsearch.bootstrap.ElasticSearch 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) Could not find the main class: org.elasticsearch.bootstrap.ElasticSearch.

Answer 1

Mingw translates paths and environment variables into UNIX equivalents. It's designed to work with its own tools, and running something foreign to it, like java.exe, doesn't always work out as you'd expect. In particular, that script builds a Java classpath in the variable ES_CLASSPATH and then passes it to Java using the -cp switch, and I bet it's passing Java a path it simply doesn't understand. What I would do is find the line that executes java.exe in that script, and make a copy of the line prepended with "echo" so that you can see the command line that's being executed. Then adjust the script to provide a proper Java classpath.
