"Maven" MAVEN deployment Web project Error Webxml attribute is required

webxml attribute is required problem

MVN install a Web project, the error is as follows:

[ERROR] Failed to execute goal Org.apache.maven.plugins:maven-war-plugin:2.1.1:war 
(Default-war) on project Com.alpha.webapp:Error assembling WAR: 
webxml attribute is required (or pre-existing web-inf/web.xml if executing in Update mode), [Help 1]

[ERROR] [Help 1] htt P://cwiki.apache.org/confluence/display/maven/mojoexecutionexception

Reason:

The default webroot for MAVEN Web projects is at Src\main\webapp. If the Web. XML is not found in this directory, the above exception is thrown.

Solve:

Need to add <webResources> configuration in Pom.xml, as follows:

  <build>
	<finalName>simple-webapp</finalName>
	<plugins>
		<plugin>
			<groupId>org.apache.maven.plugins</groupId>
			<artifactid>maven-war-plugin</artifactid >
			<version>2.1.1</version>
			<configuration>
				<webResources>
					< Resource> <!--This was relative to the Pom.xml directory--and
					<directory>webcontent</ directory>
					</resource>
				</webResources>
			</configuration>
		</plugin >
	</plugins>
  </build>

Or add <webXml> config , as follows:

<build>
	<finalName>simple-webapp</finalName>
	<plugins>
		<plugin>
			<groupId>org.apache.maven.plugins</groupId>
			<artifactid>maven-war-plugin</artifactid >
			<version>2.1.1</version>
			<configuration>

                            <webxml>webcontent\web-inf\ web.xml</webxml>        

			</configuration>
		</plugin>
	</plugins>
  </build >

<directory>WebContent</directory> is configured as a Web site root directory, such as the directory for this example:

Now MVN install the project to build success:

Deploy the war to JBoss

Locate the Com.alpha.webapp-0.0.1-snapshot.war from the local MAVEN library and copy it to the Jboss/server/*/deploy directory.

If you have already turned on JBoss, because a hot deployment is supported, you will immediately see the following information in the console indicating that the deployment was successful:

Open the Web page to see the effect:

Com.alpha.webapp-0.0.1-snapshot is the name of the war file, and Hello is the <url-pattern> defined in Web. xml
