配置jdk环境变量

vim /etc/profile

JAVA_HOME=/usr/local/jdk1.7.0_79/ JRE_HOME=$JAVA_HOME/jre #注意 jdk10解压后是没有jre目录的所以这里直接配成$JAVA_HOME/即可 去掉jre PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib export JAVA_HOME JRE_HOME PATH CLASSPATH

source /etc/profile  

发现了问题 maven从jre路径中读取的 而非jdk

添加插件 并指定jdk路径

maven-compiler-plugin 3.7.0 true /opt/soft/java/jdk1.8.0_144/bin/javac
