@romanv-jb's answer worked for me.

For those not familiar with Maven:

1. Navigate to the location of the problem version of maven-site-plugin in your local .m2 repository. Ex: ${YOUR_USER_DIR}/.m2/repository/org/apache/maven/plugins/maven-site-plugin/3.12.1/

2. Delete maven-site-plugin-3.12.1.pom.lastUpdated

3. In IntelliJ, navigate to the Maven tool window tab and select "Reload All Maven Projects".

Executing mvn clean install from your projects root directory should work the same as step 3 but I'm just showing what I did to fix the problem with the specific maven-site-plugin version in the OP.
