Knut Forkalsrud commented on MANTTASKS-197:
-------------------------------------------
Well, it is {{asm-parent}} that plays the role of my common-dependency POM.
Even if I add {{<packaging>pom</packaging>}} to my project POM (foo) it does
not change the behavior.
If you copy the code snippets above into two files in the same directory
({{pom.xml}} and {{build.xml}} respectively) and run {{ant}}, it should be
clearer.

> 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:
> {noformat}
