在Apache Felix下的OSGi Bundle中依賴項不可用（ClassNotFound）

Question

我想在由maven構建的OSGi Bundle中使用Apache Commons JCI庫。 我在Apache Felix上安裝該軟件包，一切都很正常，直到我嘗試啓動我的組件時，出現以下錯誤。我的pom.xml的樣子：

<Embed-Dependency>jtidy;scope=compile|runtime;inline=false</Embed-Dependency> 
<Embed-Directory>target/dependency</Embed-Directory> 
<Embed-StripGroup>true</Embed-StripGroup> 

<Export-Package> 
    ${project.artifactId}.*;version=${project.version}, 
    org.apache.jsp.apps.*;version=${project.version} 
</Export-Package>       

<Import-Package>*;resolution:=optional</Import-Package> 
<Private-Package></Private-Package> 

<Include-Resource> 
    {maven-resources}, 
    {maven-dependencies}, 
    src/main/scripts 
</Include-Resource> 

，我根本對依賴：

<dependency> 
     <groupId>org.apache.commons</groupId> 
     <artifactId>commons-jci-core</artifactId> 
     <version>1.0</version> 
    </dependency> 

我試着明確添加的commons-JCI-核心，以嵌入的依賴和進口Pacakage指令無濟於事。任何想法如何嵌入這種依賴，所以我的包可以看到它？

以下是錯誤IM接收：

Answer 1

原來我需要嵌入：

<Embed-Dependency> 
    commons-jci-fam;scope=compile|runtime;inline=false, 
    commons-jci-core;scope=compile|runtime;inline=false 
</Embed-Dependency> 

FilesystemAlterationListener在FAM項目，並需要其他依賴的核心項目。
