推荐答案

出现此问题是因为您的 web 应用项目的 pom.xml 中缺少以下属性.

This issue occurs because the following property is missing in the pom.xml of your web-app project.

<properties>
    <CApp.type>web/application</CApp.type>
  </properties>

将其添加到 Web-App 项目 pom.xml 后，您将能够成功导出 WAR 文件.

Once you add this to the Web-App project pom.xml you will be able to export the WAR file successfully.
