Context

mantis-examples-mantis-publish-web-sample subproject under mantis-examples does not work with the dependency recommender plugin.

Steps to reproduce

Uncomment the relevant line in settings.gradle#L42-43; looks something like //include 'mantis-examples:mantis-examples-mantis-publish-web-sample'

Expected behavior

./gradlew generateLock saveLock runs successfully without issues.

Actual Behavior

./gradlew generateLock saveLock fails instead with the stack trace below.

Execution failed for task ':mantis-examples:mantis-examples-mantis-publish-web-sample:generateLock'.
> Could not resolve all dependencies for configuration ':mantis-examples:mantis-examples-mantis-publish-web-sample:grettyRunnerJetty7'.
   > Could not find org.gretty:gretty-runner-jetty7:2.2.0.
     Searched in the following locations:
       - https://repo.maven.apache.org/maven2/org/gretty/gretty-runner-jetty7/2.2.0/gretty-runner-jetty7-2.2.0.pom
       - https://netflixoss.jfrog.io/artifactory/maven-oss-candidates/org/gretty/gretty-runner-jetty7/2.2.0/gretty-runner-jetty7-2.2.0.pom
     Required by:
         project :mantis-examples:mantis-examples-mantis-publish-web-sample

* Try:

Uncomment the sample in settings.gradle around lines 42-43, then run ./gradlew generateLock saveLock to reproduce the failure. Inspect dependency resolution for gretty-runner-jetty7:2.2.0 in the mantis-examples-mantis-publish-web-sample project. Done means the command completes successfully without the reported resolution error.
