Working with Maven Profiles

Imagine that you have the following structure in your project.

As you can see, I have config folder where I have two more folders dev and prod. Each one has two file with the same name but different values.

/config/dev/mail.properties

mail.server=smtp.gmail.com

mail.port=25

mail.from=abc@gmail.com

mail.to=xyz@gmail.com

/config/prod/mail.properties

mail.server=smtp.mycompany.com

mail.port=25

mail.from=emelendez@mycompany.com

mail.to=emelendez@mycompany.com

Why do we do that?

We have different environments and each one has his own configuration. Instead of re-write the file properties we can use profiles using maven. Configuration is attached bellow:

In your pom.xml file you need that:

	<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

	</profiles>
	</project>

If you want to build a new artifact using Dev profile you should run the following command:
mvn -Pdev clean package -Dmaven.test.skip
