Enterprise Java Development@TOPIC@
Provide groups of conditional configuration
Adds flexibility to build
Flexibility can sometimes add confusion for both developers and build tools -- be careful
Can consist of
properties
dependencies
build elements
...
Cannot include GAV elements
<profile> <!-- defines our default database -->
<id>h2db</id>
<properties>
<jdbc.driver>org.h2.Driver</jdbc.driver>

The example above defines the properties and dependencies for the H2 database driver
when the h2db profile is active
Use -P(profile) to manually trigger a profile to be included
$ mvn test -Ph2db
Use -P!(profile) to manually trigger a profile to be excluded. Use -P\!(profile) with bash shell
$ mvn test -P\!h2db
Specify an active profile in settings..xml
<activeProfiles>
<activeProfile>jboss7</activeProfile>
<activeProfile>h2db</activeProfile>
</activeProfiles>Property having a value
<profile>
<id>h2db</id>
<activation>
<property>
