maven 打jar包:mvn clean package
1.打包插件配置:
在maven项目的pom.xml文件中加入maven的打包插件:
<build>
<plugins>
<!--Spring Boot包含的maven打包插件 -->
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
2.在cmd中,先把命令行切换到Maven项目的根目录,如:D:\微服务架构\ch3 ,执行打包命令:
mvn clean package
执行结果如下:

上述执行顺序:
(1)使用清理插件:maven-clean-plugin:2.5执行清理删除已有target目录;
(2)使用资源插件:maven-resources-plugin:2.6执行资源文件的处理;
(3)使用编译插件:maven-compiler-plugin:3.1编译所有源文件生成class文件至target\classes目录下;
(4)使用资源插件:maven-resources-plugin:2.6执行测试资源文件的处理;
(5)使用编译插件:maven-compiler-plugin:3.1编译测试目录下的所有源代码;
(6)使用插件:maven-surefire-plugin:2.12运行测试用例;
(7)使用插件:maven-jar-plugin:2.4对编译后生成的文件进行打包,包名称默认为:artifactId-version,比如本例生成的jar文件:demo-0.0.1-SNAPSHOT.jar,包文件保存在target目录下。
3.执行jar包,启动项目:
进入 D:\微服务架构\ch3\target 目录,执行jar包
java -jar demo-0.0.1-SNAPSHOT.jar
