Question

我使用Maven 1.0.2和JDK 1.5一段时间没有任何问题。我决定迁移到JDK 1.6，因此我更改了JAVA_HOME环境变量（在Windows 7系统上），现在我在尝试使用maven（例如cmd中的maven install命令）时收到一条奇怪的错误消息。

Windows 7上没有command.com文件，而是cmd.exe。我不知道为什么maven只在我指向JDK 1.6时搜索它。如果我将JAVA_HOME指向JDK 1.5，一切都恢复正常。怎么了？感谢。

Answer 1

windows 7 x64没有command.com，因为它是16位应用程序我有同样的问题，我的一个朋友发现了一个很棒的解决方案

复制cmd.exe并将副本重命名为command.com，将其放在路径

中

问题解决了!!!
