Question

我正在尝试为android创建一个独立的ant构建文件。我们正在使用acceleo来生成代码。

以下是我在build.xml中采取的步骤。

编译自动生成器
生成EMTL文件
从EMTL文件生成代码

现在，我可以运行第1步，它运行正常。然后我运行第2步，它失败并出现以下错误（步骤2错误）。然后我可以运行第3步，它运行正常。然后我检查所有文件和生成的代码，一切看起来都很好。但是，第2步中的那些错误真的让我烦恼，我需要让它们得到解决。

如果您需要更多信息，我们将非常感谢您的帮助。请告知我们。

以下是build.xml中的步骤和步骤2的错误。

Answer 1

Acceleo表示无法解析元模型。您的发电机使用的包装是什么？如果您只是使用http://www.eclipse.org/EMF/2002/Ecore，则可以在不注册元模型的情况下进行编译，因为“Ecore”是一个特定的用例。否则，您应该编写元模型的包的类而不是“org.eclipse.emf.ecore.EcorePackage”。

Answer 2

从[module generateDataAccessObject(...)]中移除额外的东西实际上解决了问题。如果我只包含http://www.eclipse.org/emf/2002/Ecore and http://www.eclipse.org/acceleo/mtl/3.0，那么它就可以了。
