How to include a jar of dependency in an OSGi bundle using maven bundle plugin?
提问by Rahul Bobhate
I have an OSGi compliant bundle(jar), in which I want to add a jar of a dependency. The dependecy I want to add is of a Database Driver. That jar is not present in the lib folder of the Karaf container which I am using, and there is no way of adding it there manually. I have access only to the deploy folder, where I can deploy my bundles. I am using maven bundle plugin to package my bundle. So, I wanted to know whether there is a way to add the dependency jar in my bundle. Currently, I am adding the jar manually to the bundle by opening the bundle in 7zip and adding the jar by copying it in the jar and it works fine. I tried using the <embed-dependency>tag, but after doing that the bundle doesn't gets deployed. Is there anyway to do it ?
我有一个符合 OSGi 的 bundle(jar)，我想在其中添加一个依赖项的 jar。我要添加的依赖项是数据库驱动程序。我正在使用的 Karaf 容器的 lib 文件夹中不存在该 jar，并且无法手动将其添加到那里。我只能访问 deploy 文件夹，在那里我可以部署我的包。我正在使用 maven bundle 插件来打包我的包。所以，我想知道是否有办法在我的包中添加依赖 jar。目前，我通过在 7zip 中打开包并通过将其复制到 jar 中来添加 jar 来手动将 jar 添加到包中，并且它工作正常。我尝试使用该<embed-dependency>标签，但在使用该标签后并未部署该包。有什么办法吗？
The following is the dependency in pom.xmlwhich I want to add in the bundle:
以下是pom.xml我要添加到包中的依赖项：
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
<version>1.3.158</version>
</dependency>
The following is the build tag in pom.xml:
以下是 中的构建标记pom.xml：
<build>
<defaultGoal>install</defaultGoal>
<plugins>
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<extensions>true</extensions>
<configuration>
<instructions>
<Export-Package>
com.ct.service.userService.*,
org.h2.*
</Export-Package>
<Import-Package>
*,
org.codehaus.Hymanson.jaxrs
</Import-Package>
<Embed-Dependency>h2</Embed-Dependency>
</instructions>
</configuration>
</plugin>
</plugins>
</build>
I get the following error when I try to deploy it:
尝试部署时出现以下错误：
ERROR: Bundle com.ge.dsp.userService [205] Error starting file:D:Karaf/deploy/userService-0.0.1-SNAPSHOT.jar (org.osgi.framework.BundleException: Unresolved constraint in bundle com.ge.dsp.userService [205]: Unable to resolve 205.2: missing requirement [205.2] osgi.wiring.package; (osgi.wiring.package=org.apache.lucene.analysis))

It seems like I needed to deploy the h2-1.3.158.jaralong with my bundle and add the make some edits in the pom.xmlas follows:
似乎我需要将它h2-1.3.158.jar与我的包一起部署并添加如下进行一些编辑pom.xml：
<build>
<defaultGoal>install</defaultGoal>
<plugins>
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<extensions>true</extensions>
<configuration>
<instructions>
<Export-Package>
com.ct.service.userService.*,
<!--org.h2.* No need to export these dependency -->
</Export-Package>
<Import-Package>
*,
org.codehaus.Hymanson.jaxrs,
org.h2 <!-- Needed to import the dependencies. -->
</Import-Package>
<!--<Embed-Dependency>h2</Embed-Dependency> No need of embedding -->
</instructions>
</configuration>
</plugin>
</plugins>
