將數據添加到與PostingFormats相關的Java嵌入式Elasticsearch中的索引時出錯

Question

我在Java中使用嵌入式Elasticsearch，並將其用作主要數據存儲。 但是，當我向索引添加數據時，出現了一些奇怪的異常

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上都運行了相同的代碼，在那里運行良好

以下是異常跟蹤。

Answer 1

我實際上找到了答案，我們正在使用maven shade plugin構建JAR，我們需要添加一些配置，我們在pom配置中添加了以下內容，

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

現在它可以正常工作，希望這對尋求該問題解決方案的每個人都將有所幫助。
