Use maven plugins maven-compiler-plugin, maven-war-plugin, ex:

<build>
    <plugins>
        ...
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>2.0.2</version>
            <configuration>
                <source>1.6</source>
                <target>1.6</target>
                <encoding>${project.build.sourceEncoding}</encoding>
                <showWarnings>true</showWarnings>
                <showDeprecation>true</showDeprecation>
            </configuration>
        </plugin>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-war-plugin</artifactId>
            <version>2.1-beta-1</version>
            <configuration>
                <failOnMissingWebXml>false</failOnMissingWebXml>
                <webappDirectory>${project.build.directory}/${project.artifactId}</webappDirectory>
                <warName>${project.artifactId}_${noVer}</warName>
                <archive>
                    <addMavenDescriptor>false</addMavenDescriptor>
                    <manifest>
                        <addClasspath>false</addClasspath>
                    </manifest>
                    <manifestEntries/>
                    <manifestFile/>
                </archive>
            </configuration>
        </plugin>
        ...
    </plugins>
    <finalName>${project.artifactId}-${project.version}</finalName>
</build>

And then simply:

mvn install

will create WAR file.

You can execute mvn install goal from eclipse run configurations ...
