在下面的示例中，OSGi解析和Maven依赖支持中的所需步骤似乎存在差异/重复。
我有一个依赖于外部第三方jar的jar，在本例中是time4j。
<dependency>
<groupId>net.time4j</groupId>
<artifactId>time4j-core</artifactId>
<version>4.16</version>
</dependency>
然后我可以通过导入包并运行等来在本地运行我的简单jar。
导入OSGi时，我必须首先确保导入此jar，通常使用PAX Wrap Url。
这对于1个jar依赖项是可以的，但是当存在多个依赖项时呢？我可以使用features.xml文件来收集这些罐子，但为什么呢？我已经在我的pom.xml中指定了它们。
似乎应该有一种方法让OSGi / Karaf读取pom.xml依赖项并在需要时使用PAX Wrap url将它们导入容器。
我错过了什么吗？

很抱歉，但您的期望与现实并不一致。 首先，Maven依赖项是构建时依赖项。这就是为什么你声明你知道在运行时可用的依赖项

OSGi和Karaf都无法对构建时依赖性做任何事情。 使用OSGi 但，您可以确保您的构建依赖项在运行时也可用，并且不会干扰可能的其他库。
这就是你需要申报进口和出口等的原因。
Karaf确实可以帮助您解决某些依赖关系，例如功能文件。 如果您有一个功能定义maven项目，则所有编译范围依赖项都可以包含在一个功能文件中。
但是，OSGi解析器只查看当前可用的捆绑包，仅此而已，如果您想要某种 automagic ，则无法连接到maven。解决你需要的外部依赖关系，以确保你有
a）启用了OBR解析器（这取决于您使用的karaf版本，其中已包含4.x）和
b）手头有一个OBR存储库，Karaf Cave将是在这种情况下寻找的项目，因为它可以像maven存储库之上的代理一样驻留。
