maven profile question

Question

I am new to Maven and I have very basic question. I have one J2EE app(EAR). When I build this app I want to ignore some dependency in lib folder of my war as this jars will be provided by my server like jboss(all hibernate stuff). But when I run this war project inside embedded jetty server then I need it to be inside my lib folder. I heard about the maven profile which can be used for similar purpose. Can somebody give me an example or some detail about it or is there some other way to achieve this task. I have an EAR which contains ejb module(jar) and web module(war).

Thanks

Specify your library in a profile. Set <scope>provided</scope> for your library in a jboss profile. E.g.:

<profiles>
    <profile>
        <id>jboss</id>
        …
        <dependencies>
            <dependency>
                      <groupid>...</groupid>
                      <artifactid>...</artifactid>
                      <version>...</version>
                      <scope>provided</scope>
                </dependency>
        </dependencies>
        …
    </profile>
    <profile>
        <id>jetty</id>
        …
        <dependencies>
            <dependency>
                      <groupid>...</groupid>
                      <artifactid>...</artifactid>
                      <version>...</version>
                </dependency>
        </dependencies>
        …
    </profile>
</profiles>
