[ http://jira.codehaus.org/browse/MNG-1851?page=all ]
John Casey closed MNG-1851:
---------------------------
Resolution: Fixed
Added code preventing Pom instances from reinitializing once the mavenProject
instance variable is non-null. This should prevent the underlying project
builder from squawking.
> "Duplicate project ID found" message with maven-artifact-ant-2.0.1

> I tried upgrading my Maven 2 Ant Tasks' JAR tonight, and after doing
> so, I'm getting the following error:
> foxxy:~/dev/equinox mraible$ ant war
> Buildfile: build.xml
> init:
> [artifact:dependencies] An error has occurred while processing the
> Maven artifact tasks.
> [artifact:dependencies] Diagnosis:
> [artifact:dependencies]
> [artifact:dependencies] Unable to build project:
> /Users/mraible/Work/equinox/pom.xml
> [artifact:dependencies] Duplicate project ID found in
> /Users/mraible/Work/equinox/pom.xml
> BUILD FAILED
> /Users/mraible/Work/equinox/build.xml:27: Unable to build project:
> /Users/mraible/Work/equinox/pom.xml
> Total time: 2 seconds
> foxxy:~/dev/equinox mraible$
> I haven't been able to find the "duplicate project id" the error is
> referring to. The strange thing is if I run "mvn package" on my
> project, everything works fine with Maven 2.0.1. If I revert my
> maven-artifact-ant-2.0.1-dep.jar to maven-artifact-ant-2.0-dep.jar,
> everything works as expected.
> Here's how I declare the Maven Ant tasks in my build.xml:
> <target name="init" description="Initializes tasks and downloads
> dependencies">
> <typedef resource="org/apache/maven/artifact/ant/antlib.xml"
> uri="urn:maven-artifact-ant">
> <classpath>
> <pathelement
> location="${basedir}/lib/maven-artifact-ant-2.0-dep.jar" />
> </classpath>
> </typedef>
> <artifact:pom file="pom.xml" id="maven.project"/>
> Here's line 27 of build.xml:
> <artifact:dependencies pathId="compile.classpath"
> filesetId="compile.fileset" useScope="compile">
> <pom refid="maven.project"/>
> </artifact:dependencies>
> Thanks,
> Matt
