Upon running mvn package and java -cp es-test-1.0-SNAPSHOT.jar es.App
I am getting the following error.
Error: Unable to initialize main class es.App
Caused by: java.lang.NoClassDefFoundError: co/elastic/clients/json/JsonpMapper
This issue is only coming on ubuntu running on EC2, while there is no issue if i run it locally over my mac machine inside eclipse.

Edit - If I run the project inside using right-click + run as JAVA application then it's working fine. But if i run the same project using mvn package && java -cp target/es-test-0.0.1-SNAPSHOT.jar es.App then i am facing the same issue even on mac

这部分内容的中文翻译如下：
你正在构建该应用程序，但没有包括任何依赖项。 Maven 不会自动完成这个任务。要包括依赖项，请使用类似 maven-assembly-plugin 的工具。将以下内容添加到你的 pom.xml 文件中的依赖项部分之后：
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
<configuration>
<archive>
<manifest>
<mainClass>
es.App
</mainClass>
</manifest>
</archive>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
希望这有帮助。如果你有任何其他问题，请随时提出。
英文:
You are building the app, but not including any of its dependencies. Maven doesn't do that automagically. To include dependencies, use something like maven-assembly-plugin. Put this right after the dependencies section of your pom.xml:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
<configuration>
<archive>
<manifest>
<mainClass>
es.App
</mainClass>
</manifest>
</archive>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
