Hi sorry but I am new to java and elasticsearch. I have written a simple native script in intellij which compiles into classes fine. I then use the command line jar command to create the jar from the class files. A MANIFEST.MF file is generated but is always empty (apart from version and created by). When I put the jar into the elastic search lib directory and add the following lines to the elasticsearch.yml script.native: MyNativeScript.type: com.elasticsearch.locationscript.CustomScriptFactory Unfortunately I get the following errors Initialization Failed ... 1. No implementation for java.util.Set\ was bound.2) NoClassSettingsException[Failed to load class setting [type] with value [com.elasticsearch.locationscript.CustomScriptFactory]] ClassNotFoundException[com.elasticsearch.locationscript.CustomScriptFactory] I have tried to compile a simple helloworld jar and I found this did not work either UNTIL I modified the auto-generated (empty) Manifest file. Any help or a point to a comprehensive tutorial covering how to create the jar correctly would be much appreciated!! ttyl Matt -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

In Java, you have to add "Class-Path" to MANIFEST.MF or the class loader will get confused about dependencies. It depends on the class path when you start Elastisearch. Also, in ES, simply adding extra jars is not the preferred method for extensions. It is supposed that you put a plugin (a zip archive with jars) into the plugins folder and use es-plugin.properties instead of fiddling with jars in the lib folder. These jars are treated specially at start up time, and do not need "Class-Path" in MANIFEST.MF.

Hi thanks for the reply! I actually made a mistake in my post :/. I meant native scripts rather than plugins. I tried adding the class-path to Manifest.mf before but this did not work. Thanks for your suggestions anyway and sorry about my typo!

Yes, I understood native scripts. They should go into a plugin. Quoting the docs: "Plugins are a way to enhance the basic elasticsearch functionality in a custom manner. They range from adding custom mapping types, custom analyzers (in a more built in fashion), native scripts, custom discovery and more."

It is hard to guess what commands you executed and what your environment is. You have to set up a useable IDE environment. Currently: - I recommend IntelliJ IDEA Community Edition - Java JDK 7u65 or Java JDK 8u25 - Maven 3.2.3 - Elasticsearch 1.3 or 1.4.Beta1 With IDE support and Maven, detecting dependencies like JVM and Elasticsearch jars is a snap. For example, you could fire up a simple plugin > **[GitHub - jprante/elasticsearch-simple-action-plugin: A simple action plugin...](https://github.com/jprante/elasticsearch-simple-action-plugin)** > > A simple action plugin for Elasticsearch. Contribute to jprante/elasticsearch-simple-action-plugin development by creating an account on GitHub. then change the code to add your native script, and save it as your project.
