【问题描述】：

打包后的Elasticsearch JDBC驱动版本有一个奇怪的问题。

<dependency>
    <groupId>org.elasticsearch.plugin</groupId>
    <artifactId>x-pack-sql-jdbc</artifactId>
    <version>7.10.0</version>
</dependency>

当我在 IDEA 中运行我的代码以访问 Elasticsearch 时，它可以正常工作。

接下来，我执行mvn package 来获取一个带有依赖关系的jar。当我运行这个jar访问Elasticsearch时，报错如下：

java.sql.SQLException: Server sent bad type [action_request_validation_exception]. Original type was [Validation Failed: 1: The [0.0.0] version of the [jdbc] client is not compatible with Elasticsearch version [7.10.0];].

......

估计打包的时候版本元数据有问题，但是没找到解决办法。

我发现了一些可能有用的 Elasticsearch 源代码。

https://github.com/elastic/elasticsearch/blob/master/x-pack/plugin/sql/sql-client/src/main/java/org/elasticsearch/xpack/sql/client/ClientVersion.java#L112

【问题讨论】：

你是如何运行 jar 的？你的依赖项在你的类路径中吗？
我通过maven-assembly-plugin将依赖包打包到最终jar中，并执行java -jar xxx-jar-with-dependencies.jar

标签： java maven elasticsearch jdbc

【解决方案1】：

根据https://github.com/elastic/elasticsearch/blob/master/x-pack/plugin/sql/sql-client/src/main/java/org/elasticsearch/xpack/sql/client/ClientVersion.java#L112

我在pom.xml中添加如下配置，问题就解决了。

<manifestEntries>
    <X-Compile-Elasticsearch-Version>7.10.0</X-Compile-Elasticsearch-Version>
</manifestEntries>
