Hi there,
I'm having a really strange problem related to dependency management. I have
a parent pom with some dependencies declared in the dependency management
section, and a child pom inheriting from it. One of the dependencies is the
testng jar. Here you have excerpts from both files:
Parent pom:
<?xml version="1.0" encoding="UTF-8"?>
<project>
<modelVersion>4.0.0</modelVersion>
<groupId>org.surveyforge</groupId>
<artifactId>surveyforge</artifactId>
<packaging>pom</packaging>
<name>SurveyForge</name>
<version>0.1-SNAPSHOT</version>
[...]
<dependencyManagement>
<dependencies>
[...]
<dependency>
<groupId>org.testng</groupId>
<artifactId>testng</artifactId>
<version>4.7</version>
<classifier>jdk15</classifier>
<scope>test</scope>
</dependency>
[...]
</dependencies>
</dependencyManagement>
[...]
</project>
Child pom:
<?xml version="1.0" encoding="UTF-8"?>
<project>
<parent>
<groupId>org.surveyforge</groupId>
<artifactId>surveyforge</artifactId>
<version>0.1-SNAPSHOT</version>
</parent>
<modelVersion>4.0.0</modelVersion>
<artifactId>surveyforge-classification</artifactId>
<name>SurveyForge Classification API</name>
[...]
<dependencies>
<dependency>
<groupId>org.testng</groupId>
<artifactId>testng</artifactId>
</dependency>
[...]
</dependencies>
[...]
</project>
If I try to run any goal I get with these two files I get the following:

If I take away the classifier tag in the parent pom maven is able to
validate the pom, but (obviously) fails because it cannot download the jar.
If I include the whole dependency in the child pom and take it away from the
parent pom I also get a correct execution.
Any ideas? Is the classifier tag allowed in the dependency management
section? Is this a bug?
Best regards
Jose
