OpenDaylight有三個基礎模組，分別是controllera、openflowjava和openflowplugin，需要按順序分別編譯。（注意編譯時需要聯網）

1。準備基礎環境：

安裝JDK1.8.0和Maven3.6.0。

[email protected]:~$ sudo apt-get install openjdk-8-jdk

修改環境配置：

[email protected]:~$ sudo vim /etc/environment

在最後面加一行：JAVA_HOME="/usr/lib/jvm/java-8-openjdk-amd64"

重啟ubuntu。

Maven安裝見：

安裝完後需要更新一個配置檔案：

下載檔案：https://github.com/opendaylight/odlparent/blob/master/settings.xml

2。下載三個模組的原始碼：

[email protected]_ubuntu:~# mkdir /home/myCarbon

[email protected]_ubuntu:/home/myCarbon# git clone https://git.opendaylight.org/gerrit/p/controller.git

[email protected]_ubuntu:/home/myCarbon# git clone https://git.opendaylight.org/gerrit/p/openflowjava.git

[email protected]_ubuntu:/home/myCarbon# git clone https://git.opendaylight.org/gerrit/p/openflowplugin.git

[email protected]_ubuntu:/home/myCarbon# ll
total 20
drwxr-xr-x 5 root root 4096 Nov 18 00:15 ./
drwxr-xr-x 9 root root 4096 Nov 17 07:08 ../
drwxr-xr-x 9 root root 4096 Nov 17 08:08 controller/
drwxr-xr-x 15 root root 4096 Nov 18 00:32 openflowjava/
drwxr-xr-x 25 root root 4096 Nov 18 00:53 openflowplugin/

然後分別進三個資料夾，分別都通過git branch -a看有哪些分支，然後都切換到carbon分支：

[email protected]_ubuntu:/home/myCarbon/openflowjava# git checkout -b remotes/origin/stable/carbon

3。編譯controller

進如下目錄執行如下編譯命令：

[email protected]_ubuntu:/home/myCarbon/controller/karaf# mvn clean install -DskipTests

最後：

[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
[INFO] ------------------------------------------------------------------------
[INFO] Total time: 37:12 min
[INFO] Finished at: 2018-11-18T02:18:33-08:00
[INFO] ------------------------------------------------------------------------

現在可以進如下目錄執行如下命令啟動controller：

[email protected]_ubuntu:/home/myCarbon/controller/karaf/target/assembly/bin# ./karaf
Apache Karaf starting up. Press Enter to open the shell now...

Hit '<tab>' for a list of available commands
and '[cmd] --help' for help on a specific command.
Hit '<ctrl-d>' or type 'system:shutdown' or 'logout' to shutdown OpenDaylight.

4。編譯openflowjava
