命令行运行jar 提示找不到主程序解决方案

1.使用idea打包成jar 输入命令行：java -jar XXX.jar 提示找不到主程序

2.解决方案：在pom.xml中增加如下构建配置即可：

<build>
<plugins>
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<appendAssemblyId>false</appendAssemblyId>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
<archive>
<manifest>
<mainClass>main函数入口</mainClass>
</manifest>
</archive>
</configuration>
<executions>
<execution>
<id>make-assembly</id>
<phase>package</phase>
<goals>
<goal>assembly</goal>
</goals>
</execution>
</executions>
</plugin>

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
</plugins>

</build>

3.添加成功后，点击maven,进行编译操作

 

后双击package 在target 文件下生成jar包

再通过jar 命令运行即可
