cannot run after run mvn surefire-report:help

[c676228]

I am very new to Geb and Maven.
After I download this project. I noticed that I need to update the POM file.
However, after updating POM, the text of artifactId and version inside the report plugin

org.apache.maven.plugins
maven-surefire-plugin
2.18

still showing red and when I move my mouse to these two lines inside IntelliIDEA. It says the plugin not found. So I start to Google and tried to download this plugin to my local repository. So I typed mvn surefire-report:help in cmd.
It seems that a lot of report related plugins are downloaded from https://repo.maven.apache.org/maven2/org/apache/maven/plugins/ (even though I don't know which sub folder it downloaded to. The good part is the red highlight is gone.

So I rebuild the project and try to run the test. However, the test no longer run and I no longer see reports in folder target\surefire-reports
I only see some report in folder WikipediaRecentChangesSpec beneath target\geb-reports folder.

Can you help?

Thanks,
Betty
