How to replace web.xml during build with Maven?

Question

I have a problem with maven. i'm alredy using tomcat7-maven-plugin to deploy my war into a tomcat and it works great.

But now I would like to change a file into my generated war before to send it to servlet container. Is it possible? Particularly I want to change default web.xml with another one.

I've already tried a maven-resources-plugin as showed below:

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-resources-plugin</artifactId>
  <version>2.4.2</version>
  <executions>
    <execution>
        <id>default-copy-resources</id>
        <phase>package</phase>
        <goals>
            <goal>copy-resources</goal>
        </goals>
        <configuration>
                <overwrite>true</overwrite>
                <outputDirectory>${project.build.directory}/${project.artifactId}/WEB-INF/</outputDirectory>
                <resources>
                    <resource>
                        <directory>${project.basedir}/src/main/webapp/ext/WEB-INF</directory>
                    </resource>
                </resources>
            </configuration>
        </execution>
    </executions>
</plugin>

but this plugin replace web.xml just on target WEB-INF folder, nothing will be changed into war file. Someone can help me to find the right plugin to achive my purpose?

Answer 1

You can define your profile(in your pom.xml) within it you override the maven.war.webxml property :

<properties>
    <maven.war.webxml>path/to/your/custom/web.xml</maven.war.webxml>
</properties>

Answer 2

Solution (not mine), taken from question Maven: Customize web.xml of web-app project with Maven War Plugin and webXml parameter.

webXml The path to the web.xml file to use.

Sample usage

<profiles>
    <profile>
        <id>tomcat</id>
        <build>
            <plugins>
                <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-war-plugin</artifactId>
                    <configuration>
                        <webXml>${project.basedir}/src/main/webapp/ext/WEB-INF/web.xml</webXml>
                    </configuration>
                </plugin>
                 ...
