How to set build properties from a Mojo
I need to write a mojo that reads some data and makes it available in the pom
as ${properties}.
Is there a way to achieve this ?

That could have been a trap without you, thanks Thomas !

Hi Paul
Depending on what you need, this is not entirely trivial. If you just want to
set property 'foo' to value 'bar', then the approach below is just fine. But say
you have a property 'baz' in your pom like this:
<properties>
<baz>xx${foo}xx</baz>
</properties>
And you want 'baz' to evaluate to 'xxbarxx', then you need a bit more logic in
your Mojo. As is described here => http://plexus.codehaus.org/plexus-interpolation/
Greetings,
Thomas

The following will set a variable I_WAS_HERE to "true".
/**
* Goal which stores some properties
*
* @goal getProperty
* @phase validate
*/
The following gets the maven version and stores it as the maven.version
property.
public class MavenPropertiesMojo extends AbstractMojo {
/**
* The Maven project.
*
* @parameter expression="${project}"
* @required
* @readonly
*/
private MavenProject project;
/**
* @component
*/
private RuntimeInformation runtime;
public void execute() throws MojoExecutionException {
project.getProperties().put("I_WAS_HERE", "true");
}

Maybe the properties maven plugin does something similar to what you want.
