Custom properties in Maven based on command line switch

[reduced for simplicity]

parent
+- pom.xml
+- foo
   +- src/main/resources/test.properties

I have set profiles in parent pom.xml. Each profile is activated by a command line argument and sets the values for the properties on that group.

mvn clean compile -Dgroup1=true

The problem is that I have to duplicate the entire profile betwee开发者_StackOverflow社区n groups. I would like to only define the <properties> for each of the groups and use a single profile to control build order, plugins and other stuff.

Anyone knows if that can be done?

That sounds to me like you want to just create a different set of property files for every profile, something like this:

<profiles>
    <profile>
        <id>group1</id>
        <build>
            <filters>
                <filter>src/main/resources/propertyfile1.txt</filter>
                <filter>src/main/resources/propertyfile2.txt</filter>
            </filters>
        </build>
    </profile>
    <profile>
        <id>group2</id>
        <build>
            <filters>
                <filter>src/main/resources/propertyfile3.txt</filter>
                <filter>src/main/resources/propertyfile4.txt</filter>
            </filters>
        </build>
    </profile>
</profiles>

Now each profile gives you different values in resource filtering.

If you also need the values in the pom, you will have to do some more processing, probably using the maven properties plugin or something similar. Put the meat of the plugin definition in the main build element:

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>properties-maven-plugin</artifactId>
    <version>1.0-alpha-2</version>
    <executions>
        <execution>
            <phase>initialize</phase>
            <goals>
                <goal>read-project-properties</goal>
            </goals>
        </execution>
    </executions>
</plugin>

And configure the loaded files in the individual profiles:

<profile>
    <id>group1</id>
    <build>
        <plugins>
            <plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>properties-maven-plugin</artifactId>
                <configuration>
                    <files>
                        <file>src/main/resources/propertyfile1.txt</file>
                        <file>src/main/resources/propertyfile2.txt</file>
                    </files>
                </configuration>
            </plugin>
        </plugins>
    </build>
</profile>

I think this can be accomplished by using <pluginManagement>. You would declare build order, plugins and other stuff in the parent pom within <pluginManagement> section and then in each child, you would soecify the <plugin> along with the appropriate properties.
