Hi, I one of our java codebases that uses pmd version 5.4.1, the above mentioned method is used to set the RuleSets and then fire PMD analysis using PMD.doPMD(configuration); We are trying to upgrade the PMD version but this method has been removed from future releases. In the code base, We create custom rules by reading our custom xmls, add it to rulesets and then add set them to PMDConfiguration using net.sourceforge.pmd.PMDConfiguration.setPmdRuleSets(RuleSets pmdRuleSets) before firing PMD analysis....
