OSGI包在Apache Servicemix中未啓動

我正在開發http客戶端應用程序作爲OSGI捆綁項目，我使用apache maven創建項目文件夾結構，使用下面的命令。OSGI包在Apache Servicemix中未啓動

mvn archetype:generate -DarchetypeGroupId=org.apache.karaf.archetypes -DarchetypeArtifactId=karaf-blueprint-archetype -DarchetypeVersion=2.3.7 -DgroupId=com.techiyhub -DartifactId=integration.sms -Dversion=1.0-SNAPSHOT -Dpackage=com.techiyhub.integration.sms

上面的命令創建了項目文件夾結構，因爲我使用的是基於httpclient的應用程序。我已經在pom.xml中添加了依賴關係，如下所示。

我下面的命令執行，

MVN安裝在本地的倉庫

它創造所需的jar文件。

問題從這裏開始。我試圖部署它已經安裝了束中的Apache ServiceMix的束，但在啓動捆綁它給了一個錯誤

我已經以下命令中的ServiceMix殼

OSGi的執行：安裝MVN：com.techiyhub/integration.sms /1.0-SNAPSHOT

它得到了與包ID安裝，那麼我下面的命令執行

的OSGi：啓動302

它給了以下錯誤

錯誤執行命令：錯誤起始束：無法啓動束302：在束integration.sms未解決的約束[302]：無法解析302.0：錯過荷蘭國際集團的要求[302.0] osgi.wiring.package; （osgi.wiring.package = org.apache.http）

完整的錯誤堆棧跟蹤如下

請幫我出這一點。

當您創建一個包時，maven bundle插件會掃描您的項目的所有使用包的類文件。它在Manifest中爲這些創建Import-Package語句。

然後在運行時，您必須確保您還安裝了運行您的軟件包所需的所有必要庫。錯誤消息可幫助您找到要安裝的正確捆綁包。所以在你的情況下，你必須安裝一個導出包org.apache.http的包。

在你的情況下，這些都是：

mvn:org.apache.httpcomponents/httpcore-osgi/4.3.3 
mvn:org.apache.httpcomponents/httpclient-osgi/4.3.6

謝謝@Christain施耐德與詳細的解釋解決方案，它幫助我學習。您的解決方案解決了問題。我很想知道如何找到正確的庫，你說「錯誤信息可以幫助你找到正確的安裝包」，它在錯誤信息中提到。 – sandeep

OSGi告訴你在哪個版本範圍丟失的包。不幸的是，你必須自己找到一個匹配的包。在許多情況下，原始項目已經像上述情況一樣生成捆綁包。在其他情況下，servicemix bundles子項目可以提供幫助。我通常使用軟件包名稱在maven central上搜索。 –

謝謝@Christian Schneider – sandeep
