我正在尝试构建一个包含两个 war 文件的 ear 项目。构建 EAR 时出现“application.xml 不存在”错误。但我已将 application.xml 放在项目 META INF 文件夹中。请在下面找到代码。并提出解决方案。

下面是我的POM.XML

最佳答案

1) application.xml自 JavaEE 5.0 以来，不再需要 EAR 中的文件

2) 在 maven-ear-plugin 配置中，您不生成 application.xml文件:

 <generateApplicationXml>false</generateApplicationXml>

并且您指定了 application.xml 的位置这里:<applicationXML>src/main/application/META-INF/application.xml</applicationXML>

因此，您应该确定 application.xml文件位于此位置:src/main/application/META-INF

3)最简单的就是不用<generateApplicationXml>false</generateApplicationXml> .它避免你声明 application.xml文件。

关于java - application.xml 不存在。 maven EAR 构建期间出错，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/41312948/
