IDE 2.4 :在ElasticSearch中运行良好，但不如JAR

Question

在Intelli Java IDE中运行时，ElasticSearch 2.4客户端运行良好。当通过jar文件运行相同的代码时，java -jar <jar-path>会给出以下错误。

Exception in thread "main" NoNodeAvailableException[None of the configured nodes are available: [{#transport#-1}{<remote-ip>}{<remote-ip>:9300}]] at org.elasticsearch.client.transport.TransportClientNodesService.ensureNodesAreAvailable(TransportClientNodesService.java:290) at org.elasticsearch.client.transport.TransportClientNodesService.execute(TransportClientNodesService.java:207) at org.elasticsearch.client.transport.support.TransportProxyClient.execute(TransportProxyClient.java:55) at org.elasticsearch.client.transport.TransportClient.doExecute(TransportClient.java:288) at org.elasticsearch.client.support.AbstractClient.execute(AbstractClient.java:359) at org.elasticsearch.client.support.AbstractClient$IndicesAdmin.execute(AbstractClient.java:1226) at org.elasticsearch.action.ActionRequestBuilder.execute(ActionRequestBuilder.java:86) at org.elasticsearch.action.ActionRequestBuilder.execute(ActionRequestBuilder.java:56) at com.creo.datawarehouse.es.op.imp.IndexOperationImp.createIndex(IndexOperationImp.java:66) at com.creo.datawarehouse.es.ElasticSearch.initialise(ElasticSearch.java:27) at com.creo.datawarehouse.script.App.main(App.java:37)

POM依赖关系：

<dependency> <groupId>org.elasticsearch</groupId> <artifactId>elasticsearch</artifactId> <version>2.4.0</version> </dependency>

This question没有任何应答和what is the jar version for 2.4.0 ES version in this question。

请让我知道可能的原因或解决方案。

Answer 1

经过几个小时的调试，终于找到了解决方案。在提到这些之前，先给出一些快捷键。

1. 如果els服务器是2.4.1，maven jar也应该是2.4.1
2. Add log4j dependencies for more log in详细信息(可从这里找到)。
3. 在插件中添加阴影与集成开发环境(可能最初运行，但要运行prod，必须遵循上面的说明)。

，但为什么它在集成开发环境中运行还没有答案？
