Maven properties are value placeholder, like properties in Ant. For inheritance purposes, and to activate profiles via | or the command line, profiles have to have an ID that is unique. Properties Maven Plugin. Maven profiles provide the ability to customize build-time metadata under certain conditions, for example if a specific system property is set.

The end effect is just like the profile was inherited, but in fact the profile was NOT inherited. A profile ID may include spaces. We assign the maven.build.timestamp into a new property because there is a bug in maven which prevents from getting this property directly. While you can trigger a profile by setting the respective system property in the mvn commandline e.g. Example. How to use System Properties and Maven profiles to change Cucumber-jvm’s behaviour. We get the information like version number from the maven pom.xml file. We can do this by adding the following XML to the build section of our POM file:
