AEM WKND Apache Maven ConcurrentModificationException Build Failure

I'm going through the "Project Setup" instructions here (https://experienceleague.adobe.com/docs/experience-manager-learn/getting-started-wknd-tutorial-develop/project-setup.html?lang=en#build) and got the following failure...

[INFO] ------------------------------------------------------------------------

[ERROR] After correcting the problems, you can resume the build with the command
[ERROR]   mvn <args> -rf :aem-guides-wknd.core

...when I tried to execute the command in step 4, which is to execute the following:

$ mvn archetype:generate -B \
    -DarchetypeGroupId=com.adobe.granite.archetypes \
    -DarchetypeArtifactId=aem-project-archetype \
    -DarchetypeVersion=22 \

    -DartifactName="WKND Sites Project" \
    -DcomponentGroupName=WKND \
    -DconfFolderName=wknd \
    -DcontentFolderName=wknd \
    -DcssId=wknd \
    -DisSingleCountryWebsite=n \

    -DoptionIncludeExamples=y \
    -DoptionIncludeFrontendModule=y \
    -DpackageGroup=wknd \
    -DsiteName="WKND Site"

I navigated to http://cwiki.apache.org/confluence/display/MAVEN/MojoExecutionException, which was referenced, and it says the MojoExecutionException "is not generated by the Maven core itself but by a plugin", but I can't figure out what plugin is causing the issue. Also, the error I'm getting is "ConcurrentModificationException" and not "MojoExecutionException". Any ideas what I might be missing?

You should update bnd-maven-plugin, fix was provided in v5.1.0. Update to latest one and it should work.
