jar包：通常是开发时要引用通用类，打成包便于存放管理。
直接执行jar的方法:
1.当有Main-Class (/META-INF/MANIFEST.MF)
java -jar name.jar

2.没有Main-Class
java -cp name.jar package.ClassName

一、怎么通过MAVEN设置jar的主程序入口?

            <plugin><!-- JAR Maven 管理--><groupId>org.apache.maven.plugins</groupId><artifactId>maven-jar-plugin</artifactId><version>3.1.0</version><configuration><archive><manifest><!-- 配置主程序 java -jar 默认Class --><addClasspath>true</addClasspath><classpathPrefix>lib/</classpathPrefix><mainClass>javacore.Test</mainClass></manifest></archive></configuration></plugin>

二、怎么把pom.xml的依赖打进jar包?

            <!-- maven 打包集成插件 --><plugin><artifactId>maven-assembly-plugin</artifactId><executions><execution><phase>package</phase><goals><goal>single</goal></goals></execution></executions><configuration><descriptorRefs><!-- 将依赖一起打包到 JAR --><descriptorRef>jar-with-dependencies</descriptorRef></descriptorRefs></configuration></plugin>
