Hi,
Welcome to the community!
Per the docs
Some properties support the following wildcards in paths. The remarks for properties that support wildcards will mention this fact. If wildcards are not noted for a given property, then they are not supported for that property.
The notes for sonar.cs.opencover.reportPaths don’t mention wildcards:
sonar.cs.dotcover.reportsPaths
- Comma-delimited list of paths to the dotCover coverage reports.
