我无法在Karaf (3.0.1版)中启动捆绑包。
该包是使用maven构建的,它导入了gson。
我根据需要在maven中包含了gson:
<dependency>
<groupId>com.google.code.gson</groupId>
<artifactId>gson</artifactId>
<version>2.3.1</version>
</dependency>构建进行得很顺利。但是,在部署包时,我收到来自Karaf的以下警告:

MANIFEST.MF中的Import-Package以:
Import-Package: com.google.gson;version="[2.3,3)"我试着用以下命令改变它:
Import-Package: com.google.code.gson;version="[2.3,3)"但它给了我一个类似的错误:

我相信你有两个选择。
如果您的MANIFEST.MF中有Import-Package: com.google.gson;version="[2.3,3)",这意味着您希望从已部署的包中导入某些包,而不是从嵌入式jar中导入。在这种情况下,您应该首先部署gson-2.3.1.jar包(将此文件复制到deploy文件夹),然后部署您的包。
如果您希望将gson库作为一个简单的非OSGi jar依赖项嵌入,也可以这样做,但是您必须从Import-Package中排除它的包。

我也有同样的问题:
"Unable to resolve blah: missing requirements blah osgi.wiring.package;(osgi.wiring.package= blah-blah )未解决的需求: blah-blah osgi.wiring.package;(osgi.wiring.package=blah-blah)]。
我在src/main/java中有一个激活器类。当我在Java中创建另一个包并将我的激活器放在这里时,问题就解决了。结果是src/main/java/oneMorePackage/MyActivator
标签看起来像这样:
<Bundle-Activator>
oneMorePackage.MyActivator
</Bundle-Activator>
<Private-Package>
oneMorePackage
</Private-Package>发布于 2021-03-11 05:12:08
我也有同样的问题:
org.osgi.service.resolver.ResolutionException:无法解析根:缺少要求根osgi.identity;......[原因:无法解析com.mycompany.somemodule/1.0.0.SNAPSHOT:缺少需求
并解决了更改有问题捆绑包的pom.xml (例如com.mycompany.somemodule/pom.xml):
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<configuration>
<instructions>
<Export-Package>
com.mycompany.module.entity,
com.mycompany.somemodule.entity.v1,
com.mycompany.somemodule.entity.v2,
com.mycompany.somemodule.util
</Export-Package>
<Private-Package>
com.mycompany.somemodule,
com.mycompany.somemodule.translator
</Private-Package>
<Bundle-Name>Some Module</Bundle-Name>
<Bundle-SymbolicName>${project.name}</Bundle-SymbolicName>
<Bundle-Version>${project.version}</Bundle-Version>
</instructions>最初,问题是我只公开了这些包的一个子集:
...
<Export-Package>
com.mycompany.somemodule.entity.v2
</Export-Package>
<Private-Package>
</Private-Package>
