maven-archetype-webapp 创建不了.

Question

apache-maven-3.1.1 

conf.xml只是改了仓库路径

用 maven-archetype-quickstart 就可以 换了 maven-archetype-webapp 就不行

直接用mvn cmd运行和在IDE里面都是如此

请问为何呢

Answer 1

第二步 其实使用mvn 命令构建一个项目,命令行下 下载jar包要快些(b出错了,就在刷 多刷几次 网络原因~) 命令行构建成功后 可以发现该目录 C:UsersAdministrator{project-name} {project-name} 是一个web 项目.

Answer 2

1换个仓库地址,用阿里云的

 

<mirror>

            <id>nexus-aliyun</id>

            <mirrorOf>central</mirrorOf>

            <name>Nexus aliyun</name>

            <url>http://maven.aliyun.com/nexus/content/groups/public/</url>

</mirror>

2然后命令行 执行 mvn help:system 会下载一堆东西  多刷几下 保证能下的都下的 因为网络环境可能不稳定

3接着 命令行执行

mvn archetype:generate -DgroupId={project-packaging} -DartifactId={project-name} -DarchetypeArtifactId=maven-archetype-webapp -DinteractiveMode=false?

?又会去下载所需要的jar包   

最后 会看到

[INFO] --------------------------------------------------

?

说明该有的jar 包都有了  ,这时候去eclipse创建web项目,  豁 豁 豁 ?? 可以啦!!!

大功告成 .

Answer 3

你好： 我咋加上你的这个路径 提示 Archetype catalog does not exist 这是什么情况啊？

Answer 4

解决方案：

在Eclipse Maven配置中添加新的Catalog配置：

• http://repo1.maven.org/maven2/archetype-catalog.xml

Answer 5

非常感谢,用你的方法成功解决了问题

Answer 6

mvn archetype:generate -DgroupId={project-packaging} -DartifactId={project-name} -DarchetypeArtifactId=maven-archetype-webapp -DinteractiveMode=false
