export all defined maven project properties to file?

Question

I have a maven 3 project. In the POM, I define numerous <properties> - some under <project>, others under specific <profile>. is the a way in maven to export all declared properties to a .properties file?

My current way of doing so is to:

1. create env.properties file in src/main/resources
2. for each property 'myProp' add this line to env.properties: myProp=${myProp}
3. enable resource filtering during builds

Seems like there ought to be a way to eliminate step 2 above...

thanks, -nikita

Use properties-maven-plugin and its write-project-properties goal.
