OSGI：在片段中的另一个捆绑软件中使用代码

Question

我想使用一个Manifest.mf将OSGI片段添加到一个包中，在这里到“ org.eclipse.equinox.http.jetty”中：

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: JettyCustomize
Bundle-SymbolicName: com.company.st.console.jetty.customize
Bundle-Version: 1.0.0.qualifier
Bundle-Vendor: Company
Bundle-RequiredExecutionEnvironment: JavaSE-1.8
Fragment-Host: org.eclipse.equinox.http.jetty

不幸的是，我的代码需要在其他捆绑软件中定义的代码，此处为“ org.eclipse.jetty.io”。 因此，我将以下行添加到清单中：

Import-Package: org.eclipse.jetty.io

现在-在Eclipse中-代码可以编译。 但是，当我启动应用程序时，出现以下异常（ MyJettyCustomizer是MyJettyCustomizer中的类，每次反射时片段宿主“ org.eclipse.equinox.http.jetty”中的代码使用该类）：

java.lang.ClassNotFoundException: com.company.st.console.jetty.customize.MyJettyCustomizer cannot be found by org.eclipse.equinox.http.jetty_3.4.0.v20170503-2025

如果我从MyJettyCustomizer删除了需要“ org.eclipse.jetty.io”的代码，并再次从清单中删除了“ Import-Package：org.eclipse.jetty.io”行，则运行时和MyJettyCustomizer类都不会出现异常已正确加载。

那么，是否有可能我可以使用OSGI片段中另一个捆绑软件中的代码？

您是否碰巧将com.company.st.console.jetty.customize包放在一个以上的包/片段中？ 看来是分包问题！
