Matthew McCullough commented on MNG-2562:
-----------------------------------------
Per Wendy's last comment captured from benson0 and Jason, I'm after the same
thing. I have a .properties file that is part of our filtered resources that I
want to put the timestamp into. If I put ${build.timestamp} into the
.properties file it isn't replaced. I see this interpolation in the source of
the 2.2.0 branch of Maven, which we are using, in the file
maven-project/src/main/java/org/apache/maven/project/interpolation/BuildTimestampValueSource.java
Even though I couldn't get it to work "raw", I did find a workaround. If I put
<properties>
<mytimestamp>${build.timestamp}</mytimestamp>
</properties>
into the pom.xml and then use ${mytimestamp} in the .properties file, it indeed
does expand to 20090701-1656.

> it is useful to have the current time, for example to write out a manifest
> entry for the build time or to filter into another file.
> I'm not sure of the best way to make the format of the time configurable -

> would be nice to have a built-in.
