WebSphere Application Server Liberty Profile does not currently have Web 3.1 project support. Set the web-app version to 3.0 in your web.xml like this:
WebSphere Application Server Liberty Profile 当前不支持 Web 3.1 项目。在您的 web.xml 中将 web-app 版本设置为 3.0，如下所示：
<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
version="3.0">

I don't know if it is supported but there is always the Tomcat Java build pack. You can try it by adding "java_buildpack" to your manifest as buildpack: java_buildpack or by adding it as a -b argument in your cf pushcommand.
我不知道它是否受支持，但总有 Tomcat Java 构建包。您可以尝试通过将“java_buildpack”作为 buildpack 添加到您的清单中：java_buildpack 或将其添加为您的cf push命令中的 -b 参数。
