以create报错
[root@666 maven_work]# mvn archetype:create -DgroupId=helloword -DartifactId[root@666 maven_work]# mvn archetype:generate -DgroupId=helloword -DartifactId=helloworld
成功!!
生成以下文件:
# tree helloworld/
helloworld/
|-- pom.xml
`-- src
    |-- main
    |   `-- java
    |       `-- helloword
    |           `-- App.java
    `-- test
        `-- java
            `-- helloword
                `-- AppTest.java

7 directories, 3 files

 进到项目中,然后进行:

# 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

|-- 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

# java -cp target/helloworld-1.0v.jar helloword.App
Hello World!
