thingsboard源码编译常见问题

thingsboard 开发环境建立

http://notes.leconiot.com/thingsboard_dev_env_set_up.html#java:%E7%B1%BB%3Ccode%3Eorg.thingsboard.server.common.msg.gen%3C/code%3E_%E5%92%8C%3Ccode%3Eorg.thingsboard.server.gen.cluster%3C/code%3E_%E4%B8%8D%E5%AD%98%E5%9C%A8%E3%80%82

建议看原版，排版更好。

• git

  版本管理工具,注意配置环境变量，保证命令窗口能够直接使用。

• oracle jdk

  Which Java package do I need?
   
  Software Developers: JDK (Java SE Development Kit). For Java Developers. Includes a complete JRE plus tools for developing, debugging, and monitoring Java applications.
  Administrators running applications on a server:  -update, nor an installer. Learn more arrow
  End user running Java on a desktop: JRE: 
  

  警告：需要的jdk，非jre。选择下载jdk1.8，如果是jdk13编译会报错。

• node.js

  现在安装成功后，需要配置环境变量。保证在cmd窗口node能够直接运行，

  并且通过node -v 查询版本后修改thingsboa()rd 工程中的pom.xml。

• maven

  工程是基于maven管理，直接通过idea open，之后会自动下载各种依赖包。

  C:\Users\yuren\.m2\repository

  $tree ~/.m2 -L 2
  /home/jay/.m2
  └── repository
      ├── antlr
      ├── aopalliance
      ├── asm
      ├── backport-util-concurrent
      ├── ch
      ...
  

  按需设置maven镜像源，否则下载速度可能不稳定。在maven安装包目录下找到settings.xml更改。

      <mirrors>
          <mirror>
              
              <id>aliyun_nexusid>
              <mirrorOf>*,!maven_nexus_201mirrorOf> 
              <url>http://maven.aliyun.com/nexus/content/groups/public/url>
          mirror>
        mirrors>
  

  提示：linux在/etc/maven/settings.xml， win在zip解压安装包内查找。

• npm

  npm --registry https://registry.npm.taobao.org install express #临时使用
  npm config set registry https://registry.npm.taobao.org        #持久使用
  npm config get registry                                        #查询
  npm config rm registry                                         #删除
  npm info express
  

• idea intellj

  集成开发环境，内部集成maven。

• docker

• postgresql

  D:\my_project\thingsboard\dao\src\main\resources\sql

linux

sudo apt-get install openjdk-8-jdk maven

II. install

• Building from sources
• Contribution Guide

git clone 整个thingsboard 工程。

git clone https://github.com/thingsboard/thingsboard.git

成功clone 工程后目录结构如下。

$tree thingsboard/ -L 1
thingsboard/
├── application
├── common
├── dao
├── docker
├── img
├── k8s
├── LICENSE
├── license-header-template.txt

└── ui                               #web ui项目

这里阐述thingboard在win下的开发环境快速建立，包含工程建立、编译、调试环境。

• 装jdk、maven、node、git并且注意配置环境变量，确定命令能够直接运行，同时设置maven、node镜像源；

• 通过maven编译整个工程，下载依赖，编译protobuf 文件，java文件；

  mvn clean install
  #mvn clean install -Ddockerfile.skip=false
  mvn clean install -DskipTests           #如果不跳过测试，编译时间可能会超过1h
  

• 通过idea itellij import maven工程，编辑，调试；

maven:Some files do not have the expected license header

[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]

license 检查不通过。

maven:Could not resolve dependencies for project org.thingsboard:application:jar:2.4.1

[ERROR] Failed to execute goal on project application: Could not resolve dependencies for project org.thingsboard:application:jar:2.4.1: The following artifacts could not be resolved: org.thingsboard.rule-engine:rule-engine-components:jar:2.4.1, org.thingsboard:dao:jar:2.4.1: Could not find artifact org.thingsboard.rule-engine:rule-engine-components:jar:2.4.1 in jenkins (http://repo.jenkins-ci.org/releases) -> [Help 1]

根目录下去maven编译，不要单独每个模块，不能自动解决依赖。

Failed to run task: ‘npm install’ failed

[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 code 1) -> [Help 1]

修改版本号，保持和当前node、npm一致。

通过npm --verbose install

git Refusing to remove it.

npm ERR! path /home/jay/Desktop/project/thingsboard/ui/node_modules/mdPickers
npm ERR! code EISGIT
npm ERR! git /home/jay/Desktop/project/thingsboard/ui/node_modules/mdPickers: Appears to be a git repo or submodule.
npm ERR! git     
 
npm ERR! git Refusing to remove it. Update manually,

ui/node_modules/ 删除后再执行install。

手动删除

rm -r /home/jay/Desktop/project/thingsboard/ui/node_modules/mdPickers/

java:变量 log找不到符号

Error:(88, 21) java: 找不到符号
  符号:   变量 log
  位置: 类 org.thingsboard.server.common.data.SearchTextBasedWithAdditionalInfo<I>

使用jdk1.8 编译，先前使用了13

java:类org.thingsboard.server.common.msg.gen 和org.thingsboard.server.gen.cluster 不存在。

Error:(25, 45) java: 程序包org.thingsboard.server.common.msg.gen不存在
Error:(22, 42) java: 程序包org.thingsboard.server.gen.cluster不存在

这些类是通过protobuf 自动生成的，需要在执行java编译前进行maven clean install

maven:Failed to delete tb-http-transport.rpm

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-clean-plugin:2.5:clean (default-clean) on project http: Failed to clean project: Failed to delete D:\my_project\thingsboard\transport\http\target\tb-http-transport.rpm -> [Help 1]

第一次编译失败，再次编译可能会提示该错误，可以手动到报错路径删除，如果提示文件正在使用，需要在任务管理器杀死java进程后再手动删除。

maven:Failed to delete node.exe

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-clean-plugin:2.5:clean (default-clean) on project ui: Failed to clean project: Failed to delete D:\my_project\thingsboard\ui\target\node\node.exe -> [Help 1]

任务管理器手动杀死node.exe。

npm:npm:cb() never called!

npm install 错误

npm ERR! cb() never called!
 
npm ERR! This is an error with npm itself. Please report this error at:

• 尝试npm cache clean --force 后再次npm install 无果；

• 尝试更换淘宝镜像源后再次npm install 无果；

• 怀疑有些包下载需要，全局代理后问题依然；

• 参考网上关闭所有代理后问题依然；

• 通过log日志分析最后一个解包报错的地方，屏蔽需要的material-design-icons，新modules rxjs仍然报错；

  extract [email protected] extracted to node_modules\.staging\material-design-icons-61b4d55e (72881ms)
  

  extract [email protected] extracted to node_modules\.staging\rxjs-e901ba4c (24280ms)
  

• 参考npm ERR cb() never called 执行

  npm install --no-package-lock
  

  之后提示npm ERR! path git，添加git 到环境变量后正常。

npm:npm ERR! path git

npm ERR! path git
npm ERR! code ENOENT
npm ERR! errno ENOENT
npm ERR! syscall spawn git
npm ERR! enoent Error while executing:

添加git到环境变量。

3这里在linux上面编译报错，先前通过docker启动了thingsboard服务，停掉后再编译正常。

ThingsBoard Web UI Microservice

该目录变成变了root用户，估计是先前通过sudo npm install 新建的，改进改了回来，看来sudo还真不能随便用。

看起来像是运行时错误，这里尝试重启后再次编译。
