Vincent Siveton updated MNG-2838:
---------------------------------
Component/s: Ant tasks
> The Dependencies task of Maven Antlib should override an existing path
> reference instead of failing
> ----------------------------------------------------------------------------------------------------
>
> Key: MNG-2838
> URL: http://jira.codehaus.org/browse/MNG-2838
> Project: Maven 2
> Issue Type: Wish
> Components: Ant tasks
> Affects Versions: 2.0.4
> Environment: Solaris 10, Ant 1.7.0, Maven Antlib 2.0.4
> Reporter: Loïc Jay
>
> In the Maven Antlib 2.0.4 with Ant 1.7.0 when using the <dependencies> task
> with the pathId attribute:
> <dependencies pathId="compile.path">
> ...
> <dependencies>
> The following error is raised if a "compile.path" reference already exists:
> [maven:dependencies] An error has occurred while processing the Maven
> artifact tasks.
> [maven:dependencies] Diagnosis:
> [maven:dependencies]
> [maven:dependencies] Reference ID compile.path already exists
> In fact the error is raised even if the "compile.path" reference is defiend
> in another target whcih is not executed at runtime. This is due to Ant
> 1.7.0 which resolves references at parsing time so when the <dependencies>
> task get executed the "compile.path" reference already exists and the Maven
> <dependencies> task fails.
> Other Ant tasks like the <path> task do not fail when a reference is already
> defined. They simply override the reference.
> The maven :dependencies task should mimic the Ant <path> behaviour and accept
> to override a reference which is already defined.
> This could be implemented by removing the following code from the
> DependenciesTask.doExecute() method:
> if ( pathId != null && getProject().getReference( pathId ) != null )
> {
> throw new BuildException( "Reference ID " + pathId + " already
> exists" );
> }
> }
