Maven install Failed to execute goal Org.apache.maven.plugins:maven-war-plugin:2.1.1:war (Default-war) on Project Web_ Nanchang

When Maven was packaged into a war, error: Failed to execute goal Org.apache.maven.plugins:maven-war-plugin:2.1.1:war (Default-war) on project Web_nanchang:error assembling War:webxml attribute is required
Reason: Could not find web. XML, but the project has this file, in the webcontent/web-inf/folder, is not recognized
Workaround:
Needs to be in the Pom.xml file, plus the Maven-war-plugin plugin configuration
Add in the <build> node:

    <plugins>        <plugin>            <groupId>org.apache.maven.plugins</groupId>            < artifactid>maven-war-plugin</artifactid>            <version>2.4</version>            <configuration >                <webResources>                    <resource>                        <directory>WebContent</directory>                    < /resource>                </webResources>            </configuration>        </plugin>    </plugins >

If you do not already have the Web. xml file in your project, you need to add the following configuration:

    <plugins>        <plugin>            <groupId>org.apache.maven.plugins</groupId>            < artifactid>maven-war-plugin</artifactid>            <version>2.4</version>            <configuration >                <failOnMissingWebXml>false</failOnMissingWebXml>            </configuration>        </ Plugin>    </plugins>
