[ http://jira.codehaus.org/browse/MNG-1995?page=all ]
John Casey updated MNG-1995:
----------------------------
Fix Version/s: (was: 2.0.5)
2.1
This will have to wait for Maven 2.1.
The reason is that the filtering property in org.apache.maven.model.Resource is
actually a boolean, not a String. This is correct from a pure perspective, but
it compromises our ability to interpolate that value in the current
project-loading process. The reason is that a given POM is first read into a
org.apache.maven.model.Model intsance, /then/ interpolated, which means that
the expression above:
<resource><filtering>${filter.resources}</filtering></resource>
has already been parsed (by the XML-parsing part of the project-loading
process) into the boolean value /false/.
In order to change this, we'd need to do one of two things:
1. Change the Resource.filtering property to a String, so that expressions
would be preserved long enough to be interpolated by the current POM loading
process.
2. Change the POM loading process to read/interpolate all in one step, before a
Model instance is created.
#1 is not feasible for 2.0.x, since it would change a public API that many
plugins depend on. #2 is more reasonable, but cannot happen in the 2.0.x line,
due to the relative complexity involved with changing something so core to
Maven itself.
In fact, we already have some plans to change the POM loading process to make
it more flexible, and hopefully resolve more of these sticky interpolation
problems on the way.
