我为Mac OS X下载了最新版本的JDK8,并且还安装了maven.但是,我似乎在
Java和maven之间存在不兼容性：
myusername$mvn -version

我在用：
myusername$javac -version
javac 1.8.0_45
如何让Java和maven相互兼容？
myusername$export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.6.0_65.jdk/Contents/Home
myusername$mvn -version
Error: JAVA_HOME is not defined correctly.
We cannot execute /Library/Java/JavaVirtualMachines/jdk1.6.0_65.jdk/Contents/Home/bin/java
