Question

当我跑mvn -v时，我没有获得该版本。我得到了以下

C:\>mvn -v
Usage: java [-options] class [args...]
           (to execute a class)
   or  java [-options] -jar jarfile [args...]
           (to execute a jar file)
where options include:
    -cp <class search path of directories and zip/jar files>
    -classpath <class search path of directories and zip/jar files>
                  A ; separated list of directories, JAR archives,
                  and ZIP archives to search for class files.
    -D<name>=<value>
                  set a system property
    ......

我相信我设置了正确的路径。这是路径

C:\>path
PATH=C:\java7\bin;C:\maven\apache-maven-3.3.3\bin

C:\>echo %JAVA_HOME%
C:\java7

C:\>java -version
java version "1.7.0"
Java(TM) SE Runtime Environment (build pwa6470sr8fp10-20141219_01(SR8 FP10))IBM J9 VM (build 2.6, JRE 1.7.0 Windows 7 amd64-64 Compressed References 20141216_227497 (JIT enablebled)

知道我做错了吗？

Answer 1

设置以下环境变量。它对我来说就像一个魅力。

JAVA_HOME - C:\Program Files\Java\jdk1.7.0

M2_HOME-    D:\java\apache-maven-3.1.0-bin\apache-maven-3.1.0

path-       C:\Program Files\Java\jdk1.7.0\bin;D:\java\apache-maven-3.1.0-bin\apache-maven-3.1.0\bin;

MAVEN_HOME -D:\java\apache-maven-3.1.0-bin\apache-maven-3.1.0

在命令提示符中检查 mvn -v 。

C:\>mvn -v
Apache Maven 3.1.0 (893ca28a1da9d5f51ac03827af98bb730128f9f2; 2013-06-28 07:45:32+0530)
