当尝试在 Eclipse 的 java 项目中使用 AST 时，我收到此错误消息是运行时：线程“main”java.lang.NoClassDefFoundError 中的异常：org/eclipse/core/runtime/IAdaptable

我尝试将 core.runtime jar 添加到构建路径中，但这没有帮助。

代码一开始就失败了：

AST ast = AST.newAST(AST.JLS4);

我还尝试在我的计算机中添加所有罐子，但无济于事。有任何想法吗？

堆栈跟踪：

除了添加org.eclipse.jdt.core_[version_number].jar到您的构建路径之外，您还需要添加org.eclipse.equinox.common_[version_number].jar.
