解决方案：卸载centos自带的java，安装jdk1.8
具体步骤：
1)查看系统是否已安装的java:rpm -qa|grep java

2)卸载已安装的jdk，注意一定要有java-XXX-jdk-XXX才能下载，输入指令如下
rpm -e --nodeps java-1.8.0-openjdk-headless-1.8.0.332.b09-1.el7_9.x86_64
rpm -e --nodeps java-1.8.0-openjdk-1.8.0.332.b09-1.el7_9.x86_64

3)卸载后查看jdk输入指令：java -version

4)重新安装JDK，将对应的压缩包解压:tar -xzvf jdk-8u141-linux-x64.tar.gz

5)配置环境变量，在~/.bash_profile文件中添加如下两行
export JAVA_HOME=/usr/java/jdk1.8.0_141
export PATH=$PATH:$JAVA_HOME/bin

6)输入指令：source ~/.bash_profile使环境变量生效
7)再次使用Maven打包，可看到打包成功
