eclipse-plugin - 运行 Hello World OSGI 包时出现 FrameworkEvent 错误

Question

我是 OSGI 的初学者。我按照以下教程在 eclipse 中做一个简单的 Hello World OSGI Bundle。 http://www.javaworld.com/javaworld/jw-03-2008/jw-03-osgi1.html?page=2

在运行项目时，我在控制台中收到一堆错误。以下是这些错误:

我为 苦苦挣扎了整整一天“工作台尚未创建” 。

但是我通过以下步骤得到了 解决方案 .-

转到 运行配置 -> 删除所有目标平台 jar。

单击添加所需的包。

检查 org.apache.felix.gogo.runtime、org.apache.felix.gogo.shell、org.eclipse.eqinox.console、org.eclipse.osgi 和您的 jar 文件。

最后一步也是重要的一步。进入设置->勾选勾选“启动前清除配置区域”。

立即运行 OSGi 应用程序。

如果它对你有用，就像对我有用一样，请尽情享受。

谢谢
