The 'modules' report does not support 'url' elements using properties.
Wrong hyperlinks on index and modules page
thanks for that patch; with it I could confirm the issue.
Fixed in r1481311
Patch updating the IT to demonstrate the issue. Applying this patch and executing 'mvn verify -Prun-its', the generated 'target/it/mpir-229/target/site/modules.html' file contains the following broken link.
I've created an IT at r1481042 which looks okay to me.
Could you confirm?
