我有一个围绕OSGi和iPOJO构建的项目,我正在尝试确定它是否仍然适用于JDK 11.它目前正在使用JDK 8.由于iPOJO(1.12.1)的最新版本是最新版本,所以看起来并不太乐观. 2014年发布.更新目标和maven编译器版本后,我遇到以下问题:
[ERROR] Failed to execute goal org.apache.felix:maven-ipojo-plugin:1.12.1:ipojo-bundle (default) on project redacted: Execution default of goal org.apache.felix:maven-ipojo-plugin:1.12.1:ipojo-bundle failed. IllegalArgumentException -> [Help 1]

at …在我目前的应用程序中,我在几个地方遇到了这种模式:我在一个捆绑包中有两个服务接口,它们执行不同但相关的工作.
interface Service1 { ... }
interface Service2 { ... }
并希望单独的组件实现两者,但找到每个需要对另一个的引用:
public class Service1Impl implements Service1 {
private Service2 service2;
...
}
public class Service2Impl implements Service2 {
private Service1 service1;
...
}
三个OSGi组件模型中的哪一个(DS,Blueprint和iPOJO)允许这样:1)何时Service1Impl和Service2Impl在同一捆绑中; 2)当他们在不同的捆绑？
