异常的eclipse插件问题

我有一个非常不寻常的问题。 我用属性页开发了这个插件。当我以Eclipse应用程序的形式运行插件时，它工作得非常好，但当我导出插件并将其复制到Eclipse/dropin文件夹时，我得到了ClassNotFoundException

我的Manifest.mf如下所示：

这一定是件蠢事，但我就是看不见。

如果有人能帮我的话。我已经在这个问题上纠缠了好几个小时。

用下面的参数启动eclipse

 -console

然后在OSGi控制台中找到您的插件id，如

ss sinaut.spectrum.plugin

最后使用diag查看插件无法解析的原因

diag <id found by ss command>

diag

试着启动它，看看它的激活器是否有问题

start <id>

开始

当我执行ss sinaut.spectrum.plugin命令时，我得到以下消息：框架启动。id State Bundle没有id:/看起来你的插件不是由OSGi安装的，试试eclipse.exe-clean或者在OSGi的控制台中手动安装你的插件怎么样。是的，激活器有点问题…只是不知道是什么。我已经手动安装了插件，当我启动它时，我得到BundleException:用于bundle sinautt.spectrum.plugin的激活器…SpectrumPluginActivator无效。。。我检查了build.properties文件和类本身，一切似乎都很好。非常感谢。可能导致activator无效的一个因素是无法通过jvm解析导入某些activator类来初始化activator故障。我不确定是否理解您的意思。我已经检查了MANIFEST.MF，如果这是您的意思，那么activator是正确声明的。
