---------------------------------------------

             Summary: DependencyConvergence - should display artifact classifier in warning
                 Key: MENFORCER-353
                 URL: https://issues.apache.org/jira/browse/MENFORCER-353
             Project: Maven Enforcer Plugin
          Issue Type: Improvement
          Components: Standard Rules
    Affects Versions: 3.0.0-M3
            Reporter: Slawomir Jaranowski


dependencies to test

{code}
    <dependencies>
        <dependency>
            <groupId>org.testng</groupId>
            <artifactId>testng</artifactId>
            <version>7.1.0</version>
        </dependency>

        <dependency>
            <groupId>org.apache.maven</groupId>
            <artifactId>maven-core</artifactId>
            <version>3.5.0</version>
        </dependency>
    </dependencies>
{code}

We got information (there are other missing converge):
 
{code}
[WARNING] 
Dependency convergence error for com.google.inject:guice:4.1.0 paths to dependency are:
+-test.example.com:test:1.0.0-SNAPSHOT
  +-org.testng:testng:7.1.0
    +-com.google.inject:guice:4.1.0
and
+-test.example.com:test:1.0.0-SNAPSHOT
  +-org.apache.maven:maven-core:3.5.0
    +-com.google.inject:guice:4.0
{code}

To resolve it we should add:
{code}
            <dependency>
                <groupId>com.google.inject</groupId>
                <artifactId>guice</artifactId>
                <classifier>no_aop</classifier>
                <version>4.1.0</version>
            </dependency>
{code}

In log message information about artifact classifier is missing. It will be useful to know classifier, in other case we need do some more discovery to find it.

Eg {{dependency:tree}} show it

{code}
[INFO] --- maven-dependency-plugin:2.8:tree (default-cli) @ test ---
[INFO] test.example.com:test:jar:1.0.0-SNAPSHOT
[INFO] +- org.testng:testng:jar:7.1.0:compile
[INFO] |  +- com.beust:jcommander:jar:1.72:compile
[INFO] |  +- com.google.inject:guice:jar:no_aop:4.1.0:compile
....
{code}
