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

Question

我在Java中使用嵌入式Elasticsearch，并将其用作主要数据存储。 但是，当我向索引添加数据时，出现了一些奇怪的异常

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

版本：Java 1.7，Suse Linux 11，elasticsearch 1.1.0

我在Windows和ubuntu上都运行了相同的代码，在那里运行良好

以下是异常跟踪。

Answer 1

我实际上找到了答案，我们正在使用maven shade plugin构建JAR，我们需要添加一些配置，我们在pom配置中添加了以下内容，

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

现在它可以正常工作，希望这对寻求该问题解决方案的每个人都将有所帮助。
