# cd helloworld/ [root@666 helloworld]# ls pom.xml  src [root@666 helloworld]# mvn package 第一次编译的话，需要联网，因为Maven会自动下载依赖包.成功后会生成:target文件夹 [root@666 helloworld]# ls pom.xml  src  target   [root@666 helloworld]# tree target/ target/ |-- classes |   `-- helloword |       `-- App.class |-- helloworld-1.0v.jar |-- maven-archiver |   `-- pom.properties |-- maven-status |   `-- maven-compiler-plugin |       |-- compile |       |   `-- default-compile |       |       |-- createdFiles.lst |       |       `-- inputFiles.lst |       `-- testCompile |           `-- default-testCompile |               |-- createdFiles.lst |               `-- inputFiles.lst |-- surefire-reports |   |-- helloword.AppTest.txt |   `-- TEST-helloword.AppTest.xml `-- test-classes     `-- helloword         `-- AppTest.class   12 directories, 10 files

 手动运行jar包查看结果

?
