java.lang.NoClassDefFoundError：组织/阿帕奇/ BCEL /类文件/ ClassParser

当我执行以下java.lang.NoClassDefFoundError：组织/阿帕奇/ BCEL /类文件/ ClassParser

ClassParser parser = new ClassParser("E:\temp\TestCasing.class");

我得到以下异常：

我已经把BCEL-1.3.2。在构建路径中的jar也是。它仍然给我同样的例外。相同的代码工作正常，作为独立的Java应用程序。但不能在SWT插件项目中工作。

您需要在运行时在您的类路径中使用此jar。

你是怎么做的？ – Rahul

我已经把它放在我的构建路径中。 – Rahul

只需将jar放入你的类路径中，如果你放入构建路径，它将在构建时才可用 –
