[ http://jira.codehaus.org/browse/MNG-460?page=comments#action_40865 ]
Nicola Ken Barozzi commented on MNG-460:
----------------------------------------
With pompatch.diff one can access the POM by using
${[pom_id].[expression]}
where expression is without "project.".
It can be tested like this:
<project name="foo"
xmlns:artifact="antlib:org.apache.maven.artifact.ant"
default="test-pom">
<target name="test-pom">
<artifact:pom file="pom.xml" id="pom"/>
<artifact:setProperty property="my.artifactid"
expression="project.artifactId"
pomRefId="pom" />
<artifact:pom file="pom2.xml" id="my.maven.project"/>
<artifact:setProperty property="my.artifactid2"
expression="project.artifactId"
pomRefId="my.maven.project" />
<echo>Artifact ID2 = ${my.artifactid2}</echo>
<echo>Artifact ID2 with PropertyHelper =
${my.maven.project.artifactId}</echo>
<echo>Artifact ID = ${my.artifactid}</echo>
<echo>Artifact ID with PropertyHelper = ${pom.artifactId}</echo>
</target>
</project>
> Direct access to the POM expressions as ant properties

> URL: http://jira.codehaus.org/browse/MNG-460
> Project: Maven 2
> Type: New Feature
> Components: maven-artifact-ant
> Reporter: Nicola Ken Barozzi
> Priority: Minor
> Fix For: 2.0-alpha-3
> Attachments: POMProperties.java, pompatch.diff
>
>
> ** Disclaimer **
> I have no time now to test it fully ATM, but it should basically work.
> ****************
> This task sets up a PropertyHelper that makes it possible to resolve pom
> values directly from Ant properties.
> IOW this:
> <artifact:setProperty property="my.artifactid"
> expression="project.artifactId"
> pomRefId="my.maven.project" />
>
> then use ${my.artifactid}
> can be replaced by this:
> use ${pom:my.maven.project/project.artifactId}
> - ~ -
> Here is a sample test buildfile:
> <?xml version="1.0" encoding="UTF-8"?>
> <project name="foo"
> xmlns:artifact="antlib:org.apache.maven.artifact.ant"
> default="test-pom">
>
> <taskdef classpath="C:\Documents and
> Settings\barozzink\Desktop\m2-artifact-nkb\build\classes"
> name="pomproperties"
> classname="org.apache.maven.artifact.ant.POMProperties"/>
>
> <target name="test-pom">
> <artifact:pom file="pom.xml" id="my.maven.project"/>
> <artifact:setProperty property="my.artifactid"
> expression="project.artifactId" pomRefId="my.maven.project" />
> <echo>Artifact ID = ${my.artifactid}</echo>
>
> <pomproperties/>
> <echo>Artifact ID with PropertyHelper =
> ${pom:my.maven.project/project.artifactId}</echo>
