Question

在eclipse中尝试在java项目中使用AST时，我得到的错误信息是运行时：线程“main”中的异常java.lang.NoClassDefFoundError：org / eclipse / core / runtime / IAdaptable

我已经尝试在构建路径中添加core.runtime jar，但这没有帮助。

代码在开头就失败了：

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

我也尝试在我的电脑中添加所有的罐子，但无济于事。任何想法？

堆栈跟踪：

Answer 1

除了在您的构建路径中添加org.eclipse.jdt.core_[version_number].jar之外，您还需要添加 org.eclipse.equinox.common_[version_number].jar 。

使用AST时eclipse中的NoClassDefFoundError
