Slf4j metadata are fetched in each maven command for 4.2.0 Version

[varunbh79]

Describe the bug
The issue #2106 has resurfaced again in 4.2.0 version.
The plugin tries to download slf4j metadata on every maven command.

[INFO] Scanning for projects...
Downloading from maven-default-http-blocker: http://0.0.0.0/org/slf4j/slf4j-api/maven-metadata.xml
[WARNING] Could not transfer metadata org.slf4j:slf4j-api/maven-metadata.xml from/to maven-default-http-blocker (http://0.0.0.0/): transfer failed for http://0.0.0.0/org/slf4j/slf4j-api/maven-metadata.xml

When the Version is downgraded to 3.1.5 no metadata is downloaded and working as expected. I also attempted to exclude slf4j dependency under spring-boot-actuator and io.micrometer but didn't work.

Sample
<build> <plugins> <plugin> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-contract-maven-plugin</artifactId> <version>3.1.5</version> <extensions>true</extensions> <configuration> <testFramework>JUNIT5</testFramework> <packageWithBaseClasses>*************</packageWithBaseClasses> </configuration> </plugin> </plugins> </build>

I am also getting the similar issue, after upgrading the plugin version. slf4j dependency is getting downloaded from multiple sources whenever I do mvn clean install

Ehh it comes back again and again. I'll try to debug this when possible.
