可能问题：
---JDK 需要11版本，见下图
---IDEA的环境配置，需要切换到11，清理其他JDK版本
---IDEA的MVN版本、Java编译版本
2、thingsboard3.3.3的环境
jdk11：jdk-11.0.14_windows-x64_bin.exe
mvn：apache-maven-3.6.3
idea：2020
3、settings.xml 打开注释、关闭注释，需要镜像下载资源
E:\1000_Java\apache-maven-3.6.3\conf\settings.xml
4、License 检查不通过
[ERROR] Failed to execute goal com.mycila:license-maven-plugin:3.0:check (default) on project thingsboard: Some files do not have the expected license header -> [Help 1]
https://www.iotschool.com/wiki/tbinstall：搜索 license-maven-plugin，将整个 plugin 都注释掉
5、编译命令
mvn clean install -DskipTests
如果使用的是 mvn clean install -DskipTests 命令进行编译，那么就多尝试几次，每次编译前，要清理环境。
6、gradle-maven-plugin和settings.xml的仓库配置有关，见1和csdn链接
thingsboard:gradle-maven-plugin:1.0.10:invoke (default) on project http: Execution default of goal
