Hi, I am using java to learn elasticsearch API. I tried to start from the index api with the example code on website Resource page: Node node = nodeBuilder().node(); Client client = node.client(); ``` IndexResponse response = client.prepareIndex("twitter", "tweet", "1" ``` ) .setSource(jsonBuilder() .startObject() .field("user", "kimchy") .field("postDate", new Date()) .field("message", "trying out Elasticsearch" ) .endObject() ) .execute() .actionGet(); My problem is that importing only the elasticsearch-1.2.2.jar is not enough, and I need to go download .jar files like org/apache/lucene/search/vectorhighlight/SimpleFieldFragList org/apache/lucene/index/memory/MemoryIndex............. to solve the java.lang.NoClassDefFoundError. Is there a better efficient way to import all these required class files? (instead of google all the jar files and add into eclipse libraries) -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Use the Maven dependencies of the ES jar in the Maven repo to let the IDE build and run your code. If you want to run your code, you have to include all jars under the "lib" folder in ES\_HOME into your classpath. Maven knows about these dependencies automatically.
