org.osgi.framework.BundleActivator 的 ClassNotFoundException 尽管有导入包 [英] ClassNotFoundException for org.osgi.framework.BundleActivator despite of Import-Package

问题描述

我再次尝试使用激活器运行一个非常简单的 OSGiHello World"样式示例，并得到 org.osgi.framework.BundleActivator 的 ClassNotFoundException(参见下面的堆栈跟踪).

I tried running a really simple OSGi "Hello World"-style example with an activator after a longer while again and got a ClassNotFoundException for org.osgi.framework.BundleActivator (see stack trace below).

环境是基本的Equinox(org.eclipse.osgi_3.7.2...).所有捆绑包(除了我的)都是 ACTIVE.我在清单中的Import-Package"声明中有org.osgi.framework"，我可以在 Eclipse 的包依赖项中看到该类.

The environment is basic Equinox (org.eclipse.osgi_3.7.2...). All bundles (besides mine) are ACTIVE. I have "org.osgi.framework" in my "Import-Package" declaration in the manifest, and I can see the class in the package dependencies in Eclipse.

有人可以提示我尝试解决此问题的方法吗?

Can someone give me a hint on what to try to troubleshoot this?

亲切的问候，安德烈

推荐答案

抱歉我自己回答了这个问题，但其他人可能有类似的令人困惑的问题.发生的事情是有一个第三方库(在本例中为 Jersey)需要我包含的更新版本的 OSGi.因此，该库找不到(正确版本的)BundleActivator.

Sorry for answering this myself, but others might have a similar confusing issue. What happened was that there was a third party library (in this case Jersey) requiring a newer version of OSGi that I had included. Hence that library could not find (the right version of) BundleActivator.
