在myeclipse中创建maven项目的时候，有时候会出现如下错误：

Cannot detect Web Project version. Please specify version of Web Project through Maven project property <webVersion>. E.g.: <properties> <webVersion>3.0</webVersion> </properties>

在对应的出错的 pom.xml 文件中添加如下代码：

<build><plugins><plugin><artifactId>maven-war-plugin</artifactId><configuration><version>3.0</version></configuration></plugin></plugins></build>

右键项目——>Maven——>Update Project 如下图：

然后选择你所更改的 pom 文件所在的项目，或者全选全部更新即可消除红色叉号，如下图：
