This should be done in order to be consistent with the way most/all existing plugins handle reusing reports.
- it should be possible to set absolute paths
- non-absolute paths should be relative to the project directory, not to the Sonar working directory of the project
This should be done for every PHP tool.
For every tool, "sonar.<tool>.reportFileName" and "sonar.<tool>.reportFileRelativePath" properties should be deprecated and a warning message should be written in the log if they are used.
