Elastic Search Lucene version error
提问by Vineel
I have a very simple ES Client which will send a query to local ES server(1.4.1 version of ES) and get the results and display to the user. Now, I took this code to a different project X and tried to use it along with X because I need some APIs from X. Now, when I run the same code when i am in X, then I get this error and don't know how to resolve. Can you please help me with this. Exception in thread "main" java.lang.NoSuchFieldError: LUCENE_3_6

It seems that you are trying to use Elasticsearch and Lucene in your project as separate libraries.
看来您正试图在您的项目中将 Elasticsearch 和 Lucene 作为单独的库使用。
Elastissearch 1.4.1 is based on Lucene 4.10.2. You can check the release blog page herefor more details.
Elastissearch 1.4.1 基于 Lucene 4.10.2。您可以在此处查看发布博客页面以获取更多详细信息。
To solve your problem you will need to update your Lucene library version to 4.10 and use Version.LUCENE_CURRENT instead of LUCENE_3_6.
要解决您的问题，您需要将 Lucene 库版本更新到 4.10 并使用 Version.LUCENE_CURRENT 而不是 LUCENE_3_6。
You can find hereLucene 4.10 Core API documentation.
您可以在此处找到Lucene 4.10 Core API 文档。
I hope that this will help. Don't hesitate to comment if you have doubts.
我希望这会有所帮助。如果您有疑问，请不要犹豫发表评论。

Same error can occur in another case also - if someone unpack new ElasticSearch version in the same directory as previous version. Then it ends up with two versions of the jars in 'ElasticSearch/lib' directory. The error appears on startup.
在另一种情况下也可能发生相同的错误 - 如果有人在与以前版本相同的目录中解压新的 ElasticSearch 版本。然后它最终在 'ElasticSearch/lib' directory 中有两个版本的 jars。启动时出现错误。
In this case, the fix is to make clean ElasticSearch installation, without leftovers.
在这种情况下，修复方法是进行干净的 ElasticSearch 安装，没有剩余。
