Build TB from Source
===

:::info
編譯TB的VM環境盡可能乾淨，也不要有執行過TB Docker的部署，可能會導致衝突。

Build
---

> BUILD FAILURE :mask:

mvn clean install


> BUILD SUCCESS (==vCPUx2, 4G Mem==), 跳過單元測試，如果遇到 err 137 相關，請擴充記憶體至6G。

mvn clean install -DskipTests


We can find debian, rpm and windows packages in the target folder: **application/target**

:::info
If you need to generate local docker images, please build as below!
:::

### Build local docker images
> [Install Docker](./hMV_J0mWRGeRJyKLjjTZww?view#Install-Docker-CE)

> gnupg2 package

###Update Dockerfile
#./msa/tb/docker-postgres/Dockerfile
FROM thingsboard/openjdk11

RUN apt-get update
RUN apt-get install -y curl gnupg2

#./msa/tb/docker-cassandra/Dockerfile 
FROM thingsboard/openjdk11

RUN apt-get update
RUN apt-get install -y curl nmap procps gnupg2

> BUILD SUCCESS
* Your build account (e.g. star) needs to be in the docker group ``sudo usermod -aG docker star``

mvn clean install -DskipTests -Ddockerfile.skip=false

:::spoiler
Re-run Maven using the -X switch to enable full debug logging
e.g.
build with the command mvn clean install -DskipTests -X to get verbose output
