因为thingsboard都是国外的资料，国内基本没有参考资料。所以，记录下来源码安装当中，遇到的问题。
thingsboard官网源码安装连接：
mvn clean install -DskipTests 这一步的时候，报一下错误:<npmVersion>3.10.8</npmVersion>
需要改成对应本地的版本号。
如果还是报错，将已经安装的D:\Program Files\nodejs\node.exe(node的安装路径)复制到maven对应的目录下D:\m2\com\github\eirslett\node\10.1.0（maven下的node目录，版本号自行对应）
问题二
mvn clean install -DskipTests 这一步的时候，报一下错误:[ERROR] npm ERR! code ENOGIT
[ERROR] npm ERR! No git binary found in $PATH
[ERROR] npm ERR!
[ERROR] npm ERR! Failed using git.
[ERROR] npm ERR! Please check if you have git installed and in your PATH.
[ERROR]
[ERROR] npm ERR! A complete log of this run can be found in:
[ERROR] Failed to execute goal com.github.eirslett:frontend-maven-plugin:1.0:npm
(npm install) on project ui: Failed to run task: 'npm install' failed. (error c
ode 1) -> [Help 1]
原因：
没有安装git或者是没有配置git的环境变量
问题三
[ERROR] Failed to execute goal com.mycila:license-maven-plugin:3.0:check (default) on project xxx: Some files do not have the expected license header -> [Help 1]
原因：
因为maven会对license进行检车check，而配置文件缺少头部license声明，所以报错，无法执行下去。
<plugin>
<groupId>com.mycila</groupId>
<artifactId>license-maven-plugin</artifactId>
</plugin>
I got successful maven build.
However, this is lots of code errors in the code base. The errors are categories to four types.
- Eclipse complains log object does not define.
e.g. log.info("[{}:{}] MQTT broker connection established!", configuration.getHost(), configuration.getPort()); - Eclipse complains final variables not initialized. "The blank final field nodeId may not have been initialized"
- Object function setter & getter function undefines. I saw properties but there is not explicitly setter and getter for those properties.
4 Object not constructor. I saw some objects only has properties (some of them define as final), However, this is not constructors for those objects.
原因：
安装lombok插件
方案：https://github.com/thingsboard/thingsboard-gateway/issues/36
Lombok plugin for Eclipse
安装lombok方法：https://blog.csdn.net/dorothy1224/article/details/79280591/
问题六
src.main都作为了路径，无法形成maven项目
方法：
屏蔽pom.xml文件中的protobuf插件。涉及到的项目有application，extensions-core。屏蔽后，需要在maven选项中update project
问题七
extension-sns,extension-sqs报错：
The type org.apache.velocity.Template cannot be resolved
方法：
在这两个项目中添加依赖
<dependency>
<groupId>org.apache.velocity</groupId>
<artifactId>velocity</artifactId>
</dependency>
问题八
application报错：
ClusterAPIProtos cannot be resolved ClusterGrpcService.java
方法:
将application\target\generated-sources\protobuf\grpc-java\org\thingsboard\server\gen,
application\target\generated-sources\protobuf\java\org\thingsboard\server\gen,
extensions-core\target\generated-sources\protobuf\java\org\thingsboard\server\plugin\telmetry\gen生成的
代码（包括目录）复制到src中
问题九
忘记是什么问题了，但是需要在maven的setting.xml文件中加配置信息：
<activeProfiles>
<activeProfile>env-thing</activeProfile>
</activeProfiles>
