mvn-v显示java信息
我已经安装了jdk8 JAVA_HOME设置为mvn-v显示java信息,java,maven,Java,Maven,我已经安装了jdk8 JAVA_HOME设置为C:\Program Files\JAVA\jdk1.8.0_60(JDK 8的安装路径) PATH变量用%JAVA\u HOME%\bin修改;C:\maven\bin(maven 3.3.3的安装路径) 当我在cmd中键入mvn-v时,预期结果不会显示。相反,显示的结果等于我在cmd中键入java时的结果。 只有当cmd位于D:drive内时,我键入mvn-v时才会出现此错误。适用于C: 结果应该是:(如中所示) 结果我实际得到: D:\>

您能否分享从mvn-v
获得的确切输出以及预期得到的结果?在控制台中键入java-version
时,您会看到什么?我假设您使用的是windows控制台?请尝试将路径放在双引号(“)内的JAVA\u HOME
:set JAVA\u HOME=“C:\Program Files\JAVA\jdk1.8.0\u 60“
在环境变量中添加maven路径后。您应该在新的命令提示符窗口(而不是旧窗口)中运行命令。确认您是在新控制台还是旧控制台中运行。关闭控制台,打开新控制台,然后键入以下内容:echo%JAVA\u HOME%
和echo%PATH%
。。。告诉我们你看到了什么
