Hello Luke, Thank You for the help. I see that props can be written out and read back in and this has to be done explicitly to get the altered values back from ant.
By the way I tried using profiles and I was able to accomplish the separation I needed for my compile time variables based on any maven command line input so I went that way for now. But I really needed to know on principle if passing back from ant to maven could be done or not and it seems that it would be a very manual task :( On Fri, Aug 20, 2010 at 7:16 AM, lukewpatterson <lukewpatter...@gmail.com> wrote: > > ... more background info, trying to be more accurate and complete this time, > if anyone sees anything that should be clarified, please jump in ... > > > antrun is able to see property value changes during an <execution> run > because of two things: > > * it is manually pulling xml out of its own configuration section [1], and > resolving the expressions it each time it comes across them during ant > execution > * during the run, the properties are ant properties (initialized with > corresponding maven property values), and don't get written back to maven > properties unless you explicitly do so [2] > > > other plugins typically wouldn't be doing this, and instead rely on whatever > is passed in from the container, the stuff passed in from the container is > whatever is seen in help:effective-pom (things explicitly declared in > configuration sections) plus resolutions of default values (if the default > values contain expressions, they are evaluated right before the plugin runs) > > > > [1] > http://svn.apache.org/viewvc/maven/plugins/trunk/maven-antrun-plugin/src/main/java/org/apache/maven/plugin/antrun/AntRunMojo.java?view=markup > (line 457 is a interesting spot) > [2] > http://maven.40175.n5.nabble.com/Exporting-Ant-properties-to-Maven-td510023.html#a510117 > -- > View this message in context: > http://maven.40175.n5.nabble.com/Shuttling-Property-Values-between-Maven-and-Ant-tp2641670p2642018.html > Sent from the Maven - Users mailing list archive at Nabble.com. > > --------------------------------------------------------------------- > To unsubscribe, e-mail: users-unsubscr...@maven.apache.org > For additional commands, e-mail: users-h...@maven.apache.org > > --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@maven.apache.org For additional commands, e-mail: users-h...@maven.apache.org
