我对maven和MacOS都是新手.
我在终端中安装了maven，当获得版本设置(使用mvn -v)时，它似乎使用了JDK 1.6，而我安装了JDK 1.7.有什么问题吗？
我输入的命令如下:
blues:helloworld Ninja$ java -version
java version "1.7.0_05" Java(TM) SE Runtime Environment (build 1.7.0_05-b06) Java HotSpot(TM) 64-Bit Server VM (build 23.1-b03, mixed mode)`
blues:helloworld Ninja$ mvn -v
