线程"main“java.lang.NoSuchFieldError: ruleMemo中的异常

Question

我遵循一个不错的openArchitectureWare 教程 (它是关于使用Xpand从EMF模型生成oAW代码的)。

在最后的代码生成步骤中，当它应该生成代码时(在定义了workflow.oaw模板之后运行Root.xpt )，我将得到以下错误：

    0    INFO  WorkflowRunner     - --------------------------------------------------------------------------------------

我找了很多解决办法。大多数人说这是一个不兼容问题，例如在类路径中有几个版本的特殊jar文件，但是我在eclipse文件夹中找不到任何重复的jar文件。这真的是原因吗？如果是这样的话，在我的例子中，重复的jar文件是什么？如果没有，还有其他解决办法吗？

(我在Eclips-java-Kepler-R-Win32-x86_64上安装了oAW 4.3.1和Xpand 1.4.0 )

Answer 1

Xpand最初是作为openArchitectureWare项目的一部分开发的。但是现在，它是eclipse下的一个独立组件，不需要先安装oaw。因此，改变整个想法并使用新的教程带来了满足感:)
