Some help needed with maven-enforcer-plugin

[Markward Schubert]

Hi All!

I am struggling with the enforcer-plugin's requireSameVersions rule.
Introducing the bannedDependencies rule was successful, but somehow I seem
to not get the right configuration for requireSameVersion.

Here is my config:

<plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-enforcer-plugin</artifactId>
                <version>1.3.1</version>
                <executions>
                    <execution>
                        <id>enforce-banned-dependencies</id>
                        <goals>
                            <goal>enforce</goal>
                        </goals>
                        <configuration>
                            <rules>
                                <bannedDependencies>

<searchTransitive>true</searchTransitive>
                                    <excludes>
                                        <exclude>commons-logging</exclude>
                                    </excludes>
                                </bannedDependencies>
                            </rules>
                            <fail>true</fail>
                        </configuration>
                    </execution>
                    <execution>
                        <id>enforce-same-versions</id>
                        <goals>
                            <goal>enforce</goal>
                        </goals>
                        <configuration>
                            <rules>
                                <requireSameVersions>
                                    <dependencies>
                                        <dependency>org.slf4j:*</dependency>
                                    </dependencies>
                                </requireSameVersions>
                            </rules>
                            <fail>true</fail>
                        </configuration>
                    </execution>
                </executions>
                <configuration>
                    <ignoreCache>true</ignoreCache>
                </configuration>
            </plugin>

As a matter of fact we have

org.slf4j:slf4j-api:1.7.5

as well as

org.slf4j:com.springsource.slf4j.api:1.6.1

in our dependency tree. But still the build is SUCCESSFUL.
Did I get anything wrong here? Some misconfiguration.

I would expect that the rule as configured would enforce all
org.slf4j-group dependencies to have the same version.

Thanks for your help!
