导入maven项目Pom.xml报错：web.xml is missing and is set to true

解决办法：打pom.xml,复制一下代码配置即可，如果本身就含有build节点，则复制到节点里并去掉一个下面的build节点

  <build>
		<plugins>
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-war-plugin</artifactId>
				<version>2.6</version>
				<configuration>
					<failOnMissingWebXml>false</failOnMissingWebXml>
				</configuration>
			</plugin>
		</plugins>
	</build>
