之前可能有人问过问题,但我发现了一种非常奇怪的错误。当我mvn --version
从 bin 运行命令时,它会给出版本和其他信息。但是,当我在 bin 外运行时,它会给出异常。两个结果都在下面提到
C:\Program Files\apache-maven-3.0.5-bin\apache-maven-3.0.5\bin>mvn --version
Apache Maven 3.0.5 (r01de14724cdef164cd33c7c8c2fe155faf9602da; 2013-02-19 19:21:

我还在用户变量中设置了 JAVA_HOME,在系统环境变量中设置了 M2_HOME、M2。这些变量的输出%path%
是:
C:\Users\SAHILBHALLA>echo %JAVA_HOME%
C:\Program Files\Java\jdk1.7.0_25
C:\Users\SAHILBHALLA>echo %M2%
C:\Program Files\apache-maven-3.0.5-bin\apache-maven-3.0.5\bin
C:\Users\SAHILBHALLA>echo %M2_HOME%
C:\Program Files\apache-maven-3.0.5-bin\apache-maven-3.0.5
C:\Users\SAHILBHALLA>echo %path%

告诉我哪里错了。我应该怎么做才能从中恢复?
