已获取onos源码 master分支
已安装maven并配置/etc/profile环境变量
maven 版本3.6.3

用源码生成app框架

https://wiki.onosproject.org/display/ONOS/Template+Application+Tutorial

执行onos-create-app脚本，就在~/onos/tools/dev/bin目录下生成框架

注意参考

# groupId 定义了项目属于哪个组，组织.公司.项目，eg:com.mycom.myapp
Define value for property 'groupId': org.onos.test
# artifactId定义了当前maven项目在组中唯一的ID，项目文件夹名
Define value for property 'artifactId': Demo
# 版本号，一般直接回车（使用 1.0-SNAPSHOT）
Define value for property 'version' 1.0-SNAPSHOT: : 1.10
# package,目录结构src.main.java下一级包名，AppComponent.java所在包名
Define value for property 'package' org.onos.test: : test

onos源码不要切分支！只需要生成之后修改pom.xml文件中的onos版本
切到1.10下生成会报错

开发

进行activate 开发，pom文件中添加jar的依赖关系

idea 编译打包

先配置好maven，JDK版本记得调到8（否则报程序包javax.xml.bind.annotation不存在）

修改pom.xml

修改onos版本（原来是2.7）

    <parent>
        <groupId>org.onosproject</groupId>
        <artifactId>onos-dependencies</artifactId>
        <version>1.10.0</version>
    </parent>

添加onos.version
参考

    <properties>
        <onos.version>1.10.0</onos.version>
        <onos.app.name>org.onos.test</onos.app.name>
        <onos.app.origin>ON.Lab</onos.app.origin>
        <onos.app.title>One-Test App</onos.app.title>
        <onos.app.category>Monitoring</onos.app.category>
        <onos.app.url>http://onosproject.org</onos.app.url>
        <onos.app.requires>org.onosproject.fwd</onos.app.requires>
    </properties>

编译

编译，在编译执行的路径下的/target生成oar包。

mvn compile
  1. 如果编译出现Unknown packaging: bundle
    pom.xml添加
            <plugin>
                <groupId>org.apache.felix</groupId>
                <artifactId>maven-bundle-plugin</artifactId>
            </plugin>
            <plugin>
                <groupId>org.apache.felix</groupId>
                <artifactId>maven-scr-plugin</artifactId>
            </plugin>
  1. 使用mvn install会把oar包放到m2仓库（没必要）

安装app

UI

安装Applications右上角的 + ，注意远程传的话可能需要传两次（网络问题）
卸载：垃圾桶

CLI

oar文件可以放任意路径(本次直接放在/opt/onos/apps/)，最后安装好的app都会在onos启动的apps路径下/opt/onos/apps/。
（必须有onos源码）
/onos/tools/package/runtime/bin路径下执行

root@vpp3:~/onos/tools/package/runtime/bin# ./onos-app localhost install /opt/onos/apps/onos-app-oneping-1.10.0-SNAPSHOT.oar
{"name":"org.onosproject.oneping","id":117,"version":"1.10.0.SNAPSHOT","category":"Monitoring","description":"One-Ping-Only sample application","readme":"One-Ping-Only sample application","origin":"ON.Lab","url":"http://onosproject.org","featuresRepo":"mvn:org.onosproject/onos-app-oneping/1.10.0-SNAPSHOT/xml/features","state":"INSTALLED","features":["onos-app-oneping"],"permissions":[],"requiredApps":["org.onosproject.fwd"]}

不知道这个feature install有啥用，没有激活app但是list有变化

onos> feature:install onos-app-oneping
# list可以看到app了
onos> list

onos> feature:uninstall onos-app-oneping
# unistall也只影响了list，UI中还有应用

卸载（用app name）

root@vpp3:~/onos/tools/package/runtime/bin# ./onos-app localhost uninstall org.onosproject.oneping

激活app

UI Applications右上角的启动

onos> app (de)activate org.onosproject.$YOUR_APP_NAME

例子

使用onos-app-examples的oneping，onos-app-examples

启动onos
启动mininet拓扑（配好远程控制器地址）
onos-app-examples的oneping用mvn package后，生成的oar文件放到onos机器上，安装app，激活app

在mininet第一次 h1 ping h2
