kura - 通过Mqtt远程安装部署包失败

标签: eclipse osgi mqtt kura

我无法远程安装部署软件包,以下是我在请求主题上发送的指标 - $EDC/amir-kura/test-client/DEPLOY-V2/EXEC/download

job.id=12345678910L
dp.uri=file:/home/amir/Downloads/org.eclipse.kura.example.hello_osgi/resources/dp/hello_osgi.dp
dp.name=hello_osgi
dp.version=1.0.0
dp.download.protocol=HTTPS
dp.install.system.update=false

我在Notify主题$EDC/amir-kura/new-client/DEPLOY-V2/NOTIFY/test-client/download主题获得以下回复后,该包已成功下载

{dp.download.size=0, 
dp.download.progress=100, 
dp.download.status=COMPLETED, 
job.id=12345678910, 
client.id=test-client}

但是,安装失败了。以下是我的库拉控制台 -

根据错误,我发送了一个无效的部署包,因为它缺少Manifest,但我创建了Hello World Example中提到的.dp文件。

我该如何解决这个问题?似乎没有其他人遇到过这个问题

2 个答案:

答案 0 :(得分:0)

构建部署包时需要注意两件事。

  1. 清单必须 DP文件中的第一个条目(只是一个ZIP文件)
  2. 包含捆绑包的顺序很重要,它们必须包含在DP中的顺序与它们在清单中声明的​​顺序相同
  3. 作为第一个条目清单

    MANIFEST.MF文件包含在META-INF/目录中。通过ZIP标准,您可以在文件中添加条目以创建目录,并在文件中添加第二个条目。 DP格式支持,因此您必须在生成的DP文件中直接添加带有完整路径的文件作为第一个条目

    例如,使用maven-antrun-plugin打包DP,您可以在filesonly="true"命令上使用<jar>属性:

    <jar destfile="${basedir}/../you.final.dp_1.0.0.dp"
         manifest="${project.build.directory}/dp_stage/META-INF/MANIFEST.MF"
         includes="" filesonly="true">
        <filelist dir="${project.build.directory}/dp_stage/" files="${sortedFiles}"/>
    </jar>
    

    捆绑订单

    如果您的部署包中包含多个捆绑包,则必须包含在与Manifest相同的顺序中。您可以使用字母顺序,这是可预测的并且效果很好:-)
    将JAR复制到文件夹中,并以排序方式将它们添加到DP。使用相同的maven-antrun-plugin

    <copy file="${basedir}/../project/target/first.bundle_1.0.0.jar"
          todir="${project.build.directory}/dp_stage/bundles/" />
    
    <copy file="${basedir}/../project2/target/second.bundle_1.0.0.jar"
          todir="${project.build.directory}/dp_stage/bundles/" />
    
    <!-- Files MUST be included in the jar in the same order as they are declared in the DP MANIFEST.
        I used alphabetical order. -->
    <!-- https://ant.apache.org/manual/Tasks/jar.html -->
    <local name="sortedFiles"/>
    <pathconvert property="sortedFiles" pathsep="${line.separator}">
        <sort>
            <fileset dir="${project.build.directory}/dp_stage/" includes="bundles/*"/>
        </sort>
    </pathconvert>
    

    我在github上有一个个人project就是这样做的,请查看参考资料 POM which calls maven-antrun-plugin
    Ant task to build DP

我在@Amir评论后添加了第二个答案。另一个答案并未解决实际问题,但在其他一些案例中可能有所帮助。

我认为问题在于发送到DEPLOY-V2 cloudlet的指标。

dp.uri=file:/home/amir/Downloads/org.eclipse.kura.example.hello_osgi/resources/dp/hello_osgi.dp
dp.download.protocol=HTTPS

同样在通知中有这样的指示:

dp.download.size=0

URI表示它是本地文件系统上的文件,但协议说使用HTTPS。

如果你看DEPLOY-V2 documentation,你会看到

  

Kura 1.4.0引入了名为“DEPLOY-V2”的新版DEPLOY应用程序。引入的主要功能与包分发的不同方法有关:而不是在MQTT消息中接收包,设备仅接收下载请求,其中包含通过HTTP执行独立下载所需的所有信息
    dp.uri (字符串)。强制性。表示部署包的URI。     dp.download.protocol (字符串)必填。指定用于下载bundle / shell脚本的协议。必须设置为HTTP或HTTPS。

您需要提供有效的HTTP URL才能从中下载DP。
