Question

我用osgi + aspectj编写项目工作。它在Eclipse Kepler中运行正常，但是当我升级到eclipse 4.4（Luna）时会出现错误：

我打开Eclipse Kepler中找到的org.eclipse.osgi * .jar并查看类org.eclipse.osgi.baseadaptor.HookConfigurator

但在Luna找不到。

我已按照here的说明进行操作，它基于Eclipse Kepler，但我使用的是Eclipse Luna。请帮帮我。

Answer 1

Equinox Luna已经更改了许多内部细节，这些细节需要迁移所有equinox框架钩子实现以使用新钩子。我不清楚你已经安装了什么试图从stacktrace实现HookConfigurator。如果是支持使用aspectj进行编织的Equinox编织支撑，那么您将需要Equinox 4.4（Luna）版本发布的Equinox编织束。

如果没有，那么您所安装的编织扩展程序将需要迁移到luna中新的Equinox框架特定挂钩。

Eclipse Luna中的错误：java.lang.NoClassDefFoundError：org / eclipse / osgi / baseadaptor / HookConfigurator
