[英]Karaf / Maven - Unable to resolve: missing requirement osgi.wiring.package
我無法在 Karaf(版本 3.0.1)中啟動捆綁包。
該捆綁包是使用 maven 構建的,它導入gson 。
我根據需要在 maven 中包含了 gson:
<dependency>
<groupId>com.google.code.gson</groupId>
<artifactId>gson</artifactId>
<version>2.3.1</version>
</dependency>
構建順利。 但是,在部署捆綁包時,我收到了來自 Karaf 的警告:

未安裝捆綁包。
MANIFEST.MF
中的Import-Package
以:
Import-Package: com.google.gson;version="[2.3,3)"
我試圖改變它:
Import-Package: com.google.code.gson;version="[2.3,3)"
但它給了我一個類似的錯誤:

Google GSON 的MANIFEST.MF
(我構建捆綁包時 maven 下載的版本)是:

現在依賴項已嵌入,但 Karaf 無法啟動捆綁包。
我相信你在這里有兩個選擇。
如果您的MANIFEST.MF
中有Import-Package: com.google.gson;version="[2.3,3)"
,這意味着您希望從已部署的包中導入某些包,而不是從嵌入式 jar 中導入。 在這種情況下,您應該首先部署gson-2.3.1.jar
包(將此文件復制到部署文件夾),然后部署您的包。
如果您想將 gson 庫作為簡單的非 OSGi jar 依賴項嵌入,也可以這樣做,但是您必須從Import-Package
中排除其包:
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<extensions>true</extensions>
<configuration>
<instructions>
<Bundle-SymbolicName>${project.artifactId}</Bundle-SymbolicName>
<Import-Package>!com.google.gson,*</Import-Package>
<Embed-Dependency>gson</Embed-Dependency>
</instructions>
</configuration>
</plugin>
我有同樣的問題:
“無法解決blah-blah:缺少要求blah-blah osgi.wiring.package;(osgi.wiring.package=blah-blah)未解決的要求:[blah-blah] osgi.wiring.package;(osgi.wiring.package =胡說八道)]。
我在src/main/java
中有一個激活器類。 當我在 Java 中再創建一個包並將激活器放在這里時,問題就解決了。 結果是src/main/java/oneMorePackage/MyActivator
標簽如下所示:
<Bundle-Activator>
oneMorePackage.MyActivator
</Bundle-Activator>
<Private-Package>
oneMorePackage
</Private-Package>
我遇到了同樣的問題:
org.osgi.service.resolver.ResolutionException:無法解析根:缺少需求 [root] osgi.identity; ...... [引起:無法解析 com.mycompany.somemodule/1.0.0.SNAPSHOT:缺少要求
並且解決了更改有問題的捆綁包的pom.xml (例如com.mycompany.somemodule/pom.xml
):
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<configuration>
<instructions>
<Export-Package>
com.mycompany.module.entity,
com.mycompany.somemodule.entity.v1,
com.mycompany.somemodule.entity.v2,
com.mycompany.somemodule.util
</Export-Package>
<Private-Package>
com.mycompany.somemodule,
com.mycompany.somemodule.translator
</Private-Package>
<Bundle-Name>Some Module</Bundle-Name>
<Bundle-SymbolicName>${project.name}</Bundle-SymbolicName>
<Bundle-Version>${project.version}</Bundle-Version>
</instructions>
最初,問題是我只公開了這些包的一個子集:
...
<Export-Package>
com.mycompany.somemodule.entity.v2
</Export-Package>
<Private-Package>
</Private-Package>
...
我有這種錯誤。 這意味着 Karaf 沒有找到“依賴包”。
首先安裝依賴包,然后安裝你的包。
例如:
osgi:install mvn:com.yourCompany.corePackage.subPackage/yourDependencyBundle/1.0.0-SNAPSHOT
然后
osgi:install mvn:com.yourCompany.corePackage.subPackage/yourBundle/1.0.0-SNAPSHOT
