在Eclipse中使用Acceleo无法从UML生成java [英] Can't generate java from UML using Acceleo in Eclipse
问题描述
我正在跟随从uml生成java代码的教程。该链接是 http://wiki.eclipse.org/Acceleo/Getting_Started 。但是当我尝试运行generate.mtl文件时，错误日志给我一个消息：
无法加载类org .eclipse.acceleo.module.sample.main.Generate
从项目org.eclipse.acceleo.module.sample
它也给了我警告：
无法加载类org.eclipse.acceleo.module.sample。 main.Generate。
检查其包含的包是否被导出。

我把[comment @ main /]放在模板行下方，执行教程中的所有步骤，我真的不知道问题是什么。
感谢任何帮助或反馈。
我通过更新MANIFEST.MF文件中的类路径来更正此错误：
我添加了bin / projet的文件夹。现在可以正常工作。

I am new to Eclipse and Acceleo, and I have been trying to complete the First Generator Model Tutorial. I am using Kepler 4.3 and Acceleo 3.X. I am following the tutorial that generates java code from uml. The link is http://wiki.eclipse.org/Acceleo/Getting_Started. But when I try to run the generate.mtl file, the error log gives me the message:
Couldn't load class org.eclipse.acceleo.module.sample.main.Generate
from project org.eclipse.acceleo.module.sample
It also gives me the warning:
Couldn't load class org.eclipse.acceleo.module.sample.main.Generate. Check that its containing package is exported.
and The activator org.eclipse.acceleo.module.sample.Activator for bundle org.eclipse.acceleo.module.sample is invalid

I have put the [comment @main/] below the template line and do all the steps in the tutorial, i really have no idea what the problem is.
I would appreciate any help or feedback.
I corrected this error by updating the classpath in the MANIFEST.MF file :
I added the bin/ folder of the projet. It now works properly.
