将数据添加到与PostingFormats相关的Java嵌入式Elasticsearch中的索引时出错

Question

I am using embedded elasticsearch in java and I am using it as a primary data storage. But when I am adding data to index it's giving some weird exception

java.lang.NoClassDefFoundError: Could not initialize class org.elasticsearch.index.codec.postingsformat.PostingFormats.

Versions: Java 1.7, Suse Linux 11, elasticsearch 1.1.0

I ran same code on my windows as well as ubuntu, it's running fine there

Following is the exception trace.

Answer 1

I actually found answer of this, we are using maven shade plugin to build the JAR and we required to add some of its configurations, we have added following in its pom configurations,

<transformers>
      <transformer implementation="org.apache.maven.plugins.shade.resource.ServicesResourceTransformer"/>
</transformers>
<minimizeJar>false</minimizeJar>

Now its working fine, hope this will be helpful for everybody looking for solution of this problem.
