1、maven-compiler-plugin:3.8.1-- Fatal error compiling

可能問題：
---JDK 需要11版本，見下圖
---IDEA的環境配置，需要切換到11，清理其他JDK版本
---IDEA的MVN版本、Java編譯版本
2、thingsboard3.3.3的環境
jdk11：jdk-11.0.14_windows-x64_bin.exe
mvn：apache-maven-3.6.3
idea：2020
3、settings.xml 打開注釋、關閉注釋，需要鏡像下載資源
E:\1000_Java\apache-maven-3.6.3\conf\settings.xml
4、License 檢查不通過
[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，將整個 plugin 都注釋掉
5、編譯命令
mvn clean install -DskipTests
如果使用的是 mvn clean install -DskipTests 命令進行編譯，那么就多嘗試幾次，每次編譯前，要清理環境。
6、gradle-maven-plugin和settings.xml的倉庫配置有關，見1和csdn鏈接
thingsboard:gradle-maven-plugin:1.0.10:invoke (default) on project http: Execution default of goal
