acceleo編譯器，5：元模型無法解析

Question

我正在嘗試爲android創建一個獨立的ant構建文件。我們正在使用加速器來生成代碼。

以下是我在build.xml中採取的步驟。

1. 編譯汽車發電機
2. 生成EMTL文件
3. 眼下生成從EMTL文件

的代碼，我可以運行步驟1中，它工作正常。然後我運行第2步，它失敗，出現以下錯誤（第2步錯誤）。然後我可以運行第3步，它工作正常。然後我檢查我的所有文件和生成的代碼，一切都很好。但是，步驟2中的那些錯誤確實困擾着我，我需要讓他們解決。

任何幫助將不勝感激，如果你需要更多的信息，請讓我知道。

下面發佈是步驟2在build.xml步驟和錯誤

Answer 1

從[module generateDataAccessObject(...)]中刪除多餘的東西實際上解決了問題。如果我只包括http://www.eclipse.org/emf/2002/Ecore and http://www.eclipse.org/acceleo/mtl/3.0那麼它的工作原理。

Answer 2

Acceleo表明元模型無法解析。你的發電機使用什麼軟件包？如果您僅使用http://www.eclipse.org/EMF/2002/Ecore，則可能無需註冊元模型即可進行編譯，因爲「Ecore」是特定用例。否則，您應該編寫您的元模型的包的類而不是「org.eclipse.emf.ecore.EcorePackage」。
