我是第一次安装Maven 3.1.1。在“5分钟内行家”入门指南中
http://maven.apache.org/guides/getting-started/maven-in-five-minutes.html
它说来验证安装mvn --version
我得到了预期的答复:
Apache Maven 3.1.1 (0728685237757ffbf44136acec0402957f723d9a; 2013-09-17 11:22:22-0400)
Maven home: C:\applications\programming\apache-maven-3.1.1
Java version: 1.6.0_17, vendor: Sun Microsystems Inc.
Java home: C:\applications\programming\java_6_17\jre
Default locale: en_US, platform encoding: Cp1252
OS name: "windows 7", version: "6.1", arch: "x86", family: "windows"
下一步，在“创建项目”下，它表示要创建一个新目录，在该目录中打开命令提示符，然后执行
mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false我创建了一个名为
xjmaven的目录，并在其中运行命令，但该目录不起作用。这是响应:[R:\jeffy\programming\sandbox\xjmaven]mvn archetype:generate -DgroupId=xbnjava -DartifactId=XBN-Java -Darchetype ArtifactId=maven-archetype-quickstart -DinteractiveMode=false

我查找了参数
groupId，artifactId和archetypeArtifactId，并尝试了一些不同的值(如您在上面看到的)，但是我仍然得到相同的BUILD FAILURE响应。我手动将
pom.xml文件(来自同一网页)放在xjmaven目录中，然后再次运行。它下载了一堆东西(尽管不是xjmaven)，但随后失败，并显示以下消息:[INFO] Generating project in Interactive mode

重复该命令将给出以下响应:

我删除了
pom.xml(这是目录中的唯一文件...下载的内容不存在)，然后重新开始。正如我在上面所写，一切都会发生(严重)。我记得几年前尝试过Maven，也无法超越入门阶段。
如果有人对如何克服这个问题有任何建议，将不胜感激。真的很沮丧。
最佳答案
也许您正在使用Windows PowerShell？
如果是这样，则需要在参数定义两边加上引号:
mvn archetype:generate "-DarchetypeGroupId=org.apache.maven.archetypes" "-DgroupId=com.mycompany.app" "-DartifactId=my-app"
