This could be a nothing for an experienced developer. However, iam having this problem when trying to build my project in linux environment(Red Hat). It gives me following error.

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-war-plugin:2.1.1:war (default-war) on project ABC: Error assembling WAR: webxml attribute is required (or pre-existing WEB-INF/web.xml if executing in update mode) -> [Help 1]

However, it works perfectly in windows environment.

Here is my Pom

    Ok, I found the cause.
    It is just i have missed to include web.xml configuration in war plugin

    <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-war-plugin</artifactId>               
            <version>2.1.1</version>
            <configuration>
                 <webXml>src\main\webApp\WEB-INF\web.xml</webXml>
            </configuration>
        </plugin>

    Strange…
