Dependency with packaging=pom shows up in the classpath
-------------------------------------------------------
Key: MANTTASKS-197
URL: http://jira.codehaus.org/browse/MANTTASKS-197
Project: Maven 2.x Ant Tasks
Issue Type: Bug
Components: dependencies task
Affects Versions: 2.1.1
Environment: Mac OSX, Ant 1.8.1
Reporter: Knut Forkalsrud
My use case is that I have a set of common dependencies that I use across many
projects.
In order to save me some typing I created a pom whose sole purpose is to depend
on all
the common dependencies, so that each of my projects can depend on only this
one pom.
The problem is that the pom file gets included in the classpath, an the junit
task shows
an annoying error because it can't make sense of it as a directory or jar file.
A relatively simple testcase to show the issue is this pom.xml:
{code:xml}<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
http://maven.apache.org/xsd/maven-4.0.0.xsd";
xmlns="http://maven.apache.org/POM/4.0.0";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
<modelVersion>4.0.0</modelVersion>
<groupId>foo</groupId>
<artifactId>bar</artifactId>
<version>1.0</version>
<dependencies>
<dependency>
<groupId>asm</groupId>
<artifactId>asm-parent</artifactId>
<version>3.1</version>
<type>pom</type>
</dependency>
</dependencies>
</project>
{code}
An the following build.xml in the same directory:
{code:xml}
<?xml version="1.0" encoding="UTF-8"?>
<project name="foo" default="test"
xmlns:artifact="antlib:org.apache.maven.artifact.ant">
<target name="test">
<artifact:pom file="${basedir}/pom.xml" id="maven.project"/>
<artifact:dependencies pathId="maven2.test.classpath"
filesetId="test.fileset">
<pom refid="maven.project"/>
</artifact:dependencies>
<echo>${toString:maven2.test.classpath}</echo>
</target>
</project>
{code}
When I run this I expect the output from <echo> to list the classpath
consisting of the jars dependencies from {{asm-parent}}. That pom happens to
have no jar dependencies, so I expect the output to be empty. Instead I get
the path of the pom file.
In a more realistic example I will use this as a classpath argument to <junit>
and get an error like:

When I read MANTTASKS-41 I can't help but think it revolves around the same
culprit, but I'm not expert enough to pinpoint the issue.
