[jira] Commented: (MNG-609) Filtered resources should support ${pom.*} and ${project.*} syntax only, not ${*}, for POM properties

["John Fallows (JIRA)" <ji...@codehaus.org>]

    [ http://jira.codehaus.org/browse/MNG-609?page=comments#action_45958 ] 

John Fallows commented on MNG-609:
----------------------------------

In what sense is this a backwards compatibility issue? 

I thought that the pom-variables-resolved-during-resource-filtering feature was added to the trunk since the m2 alpha-3 release.  Perhaps not.

>      Project: Maven 2

> I noticed that the latest code on the trunk adds support for filtered resources, including the ability to refer to pom properties, in addition to any filter properties defined in filter.properties.
> For example:
>  src/main/resources/my-resource.txt
> with contents
>  ${version}
> It seems that each property of the POM is exposed as an independent top-level variable.
> I was expecting the filtered resource file syntax to be...
>  ${project.version}
> ...since that would be consistent with expressions used in the pom.xml file, such as:
>  <sourceDirectory>${project.basedir}/src/main/java</sourceDirectory>
> This has the added benefit of reduced collision space for top-level variables in filtered resource files.
> Recommend that top level variables, such as ${version} are _not_ supported as implicit filter variables, only ${pom} and ${project}.
