我在 Windows 7 上使用 Maven 3.5。环境变量“M2_HOME”和“JAVA_HOME”设置正确，并且“JAVA_HOME\bin”和“M2_HOME\bin”包含在我系统的 PATH 中。
我删除了 .m2 目录下的所有文件并从命令行执行：
$mvn 原型：生成 -DinteractiveMode=true
Maven成功下载了一些文件，直到显示如下：

当我从以下位置手动下载有问题的文件时： http ://repo.maven.apache.org/maven2/org/apache/maven/archetype/maven-archetype/2.2/maven-archetype-2.2.pom 我注意到该文件是格式不正确（我猜 XML 应该是有效的，但它不是）。
这是一个已知的错误还是我在这里做错了什么？
