解決方案：

在/etc/profile配置java的環境變量： 你的mvn 項目是用哪個版本的jdk. 就要配置那個版本的jdk.

我的配置如下：（根據你自己的JDK的位置：）

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_40.jdk/Contents/Home  （你自己的jdk的位置）
export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH:$HOME/bin

然後強制保存文件命令：

:w !sudo tee %

此時在進入項目執行：

$ git pull origin master

繼續mvn clean install;
