Adob​​e CQ/AEM akka集成

Question

我正在玩Adobe adobe cq和scala，因此我能够编写scala服务并将其部署到osgi容器。

后来我试着用阿卡以下tutorial整合，我收到以下错误

它抛出NoClassDefFoundError的，但我可以看到在Scheduler.scala该类文件

如果添加sun.misc到org.osgi.framework.bootdelegation在sling.properties没有为您工作，请尝试添加以下OSGI片段人为因素作为依赖项：

<dependency> 
    <groupId>com.github.livesense</groupId> 
    <artifactId>org.liveSense.fragment.sun.misc</artifactId> 
    <version>1.0.5</version> 
</dependency> 

该软件包使用sun.misc软件包扩展了System Bundle导出列表，这样OSGi软件包可以引用Sun的misc实现，而不需要OSGi框架本身以非便携方式提供它。

http://mvnrepository.com/artifact/com.github.livesense/org.liveSense.fragment.sun.misc

换言之，该片段附接到系统bundle并修改出口，使得sun.misc包由其他束暴露进行导入。默认情况下，框架包仅导出java.*和javax.*包。对于Groovy/Scala/Akka中的某些动态和低级语言功能，sun.misc包是必需的。
