NoClassDefFoundError: org/eclipse/cdt/core/CCorePlugin

Question

我正在开发一个插件，以使用 eclipse Indigo 通过 java 代码创建/编译/运行 CDT 项目。 我可以在 Eclipse PDE 中成功运行我的插件。 但是当我将它部署到一个 jar 文件中，并将它安装在一个新的 eclipse-java-indigo-win32 中时， 我无法运行我的插件。 它给出了以下错误。

我在插件依赖选项卡中添加了 org.eclipse.cdt.core jar 文件。

请指导我解决这个问题。

我遇到了类似的问题并尝试了许多不同的“解决方案”（其中一些对其他人有用，但没有一个对我有用）。我终于发现How to use and package a JAR file with my Android app? 有答案（至少对我而言）——我必须使用 JDK 1.6 重新编译 jar。用 1.7 编译从来没有用过。一旦我重新编译并重新加载了新的 jar，它就工作得很好。希望对您有所帮助。
