Using Maven for multiple deployment environment (production/development)

Question

I have a web app in Maven, with the default directory structure. No problem there. The default directory structure has some property files that point to my localhost database.

Currently I create an Ant script to create different war files - one for production and one for development, using these commands:

ant deploy-dev
ant deploy-prod
ant deploy-sit
ant deploy-uat

So basically they create a war file and then update the war file by plugging in the properties file

Is there something like that in maven (different war created depending on the configuration)?

if so, how do i do that?

i tried mvn warbut it just creates a war

I prefer use maven profiles for this situation. For example we have directory structure:

src/main/resources
|
+- local
|  |
|  `- specific.properties
+- dev
   |
   `- specific.properties

In pom.xml define two profiles:

<profiles>
    <profile>
        <id>local</id>
        <activation>
            <activeByDefault>true</activeByDefault>
        </activation>
        <build>
            <resources>
                <resource>
                    <directory>src/main/resources/local</directory>
                </resource>
            </resources>
        </build>
    </profile>
    <profile>
        <id>dev</id>
        <build>
            <resources>
                <resource>
                    <directory>src/main/resources/dev</directory>
                </resource>
            </resources>
        </build>
    </profile>
</profiles>

In that case, I dont need to update every time pom.xml for new files. In IDE simply switch profiles, or use -P flag from command line.

UPD: what to do if some properties are the same for configurations? Make the configuration like this:

<profiles>
    <profile>
        <id>local</id>
        <activation>
            <activeByDefault>true</activeByDefault>
        </activation>
        <build>
            <resources>
                <resource>
                    <directory>src/main/resources</directory>
                </resource>
                <resource>
                    <directory>src/main/config/local</directory>
                </resource>
            </resources>
        </build>
    </profile>
    <profile>
        <id>dev</id>
        <build>
            <resources>
                <resource>
                    <directory>src/main/resources</directory>
                </resource>
                <resource>
                    <directory>src/main/config/dev</directory>
                </resource>
            </resources>
        </build>
    </profile>
</profiles>

Common part will be stored in src/main/resources and other configs will be in appropriate folders in config directory.
