通过maven打nar包报错问题记录
进入项目目录，输入mvn clean install

[ERROR] After correcting the problems, you can resume the build with the command
[ERROR] mvn <goals> -rf :nifi-demo-processors因为之前一直是可以打包且没有报错的，换了一台电脑，打包就发生了错误。误以为是JAVA_HOME没有配置对，倒腾了很久，差点重装jdk。后来经过多番百度，发现是插件没有下载成功。使用命令mvn clean install -Dmaven.test.skip=true 跳过test步骤，运行成功。也可以直接将插件的jar包放到maven的本地资源库中。
