Get system/environment variable into MOJO help

["Thanh T." <co...@gmail.com>]

Hi all,
I was able to get the POM properties and project into mojo thanks to
Dan Tran and Alexandre Poitras for the help. Now I couldn't get the
environment variables into mojo. Here's my question where can I get a
list parameter expression. For example if I want to pass in the
project build folder i would do.

/**
* @parameter expression="${project.build.directory}"
* ...
*/
private File buildDirectory;

how can I pass the system properties into mojo? i don't know the
expression for system properties. Can anyone point me to a place where
they have a list of expression? I tried to find the default maven 2
properties but couldn't from their site either. thanks

Hello,

AFAIK, system properties doesn't have expressions like project properties
do.

Using System.getProperty() will work, but you'd be better off passing
parameters (just like how you mentioned) as the advantages are: you could
inject the values thru the command line and you could specify the parameters
in pom.xml.

Did I get you right?  Kindly correct me if I'm wrong. :)

Cheers!
