application.xml不存在。在Maven EAR構建中出現錯誤

Question

我正在嘗試構建一個帶有兩個內部war文件的ear項目。在構建EAR時，我收到錯誤，因爲「application.xml不存在」。但我已將application.xml放置在項目META INF文件夾中。請找到下面的代碼。並提出解決方案來解決這個問題。

下面是我的pom.xml

Answer 1

1）application.xml文件中的EAR不需要因爲JavaEE的5.0

2）不再在行家-EAR-插件配置，你不會生成application.xml文件：

<generateApplicationXml>false</generateApplicationXml> 

和指定的application.xml這裏的位置：最簡單的不使用<generateApplicationXml>false</generateApplicationXml>src/main/application/META-INF

3）：<applicationXML>src/main/application/META-INF/application.xml</applicationXML>

所以，你應該確保application.xml文件是在這個位置。它避免了你聲明application.xml文件。
