Hi, explicit receiver parameters are an obscure new language feature in Java 8. See blog post by Stephen Colebourne: http://blog.joda.org/2015/12/explicit-receiver-parameters.html I tried it out with the Maven PMD plugin 3.6 and it looks like PMD cannot parse the code. Here's a small example project, see the Readme: https://github.com/arend-von-reinersdorff/explicit-receiver-parameters-example That this very obscure feature is not parsed, is in my opinion a minor issue. What I found more annoying is that the file with the code was apparently silently dropped from the analysis. When a file cannot be parsed, I would expect a warning or info message. Main.java contains an "empy if block" violation and demo code to demonstrate explicit receiver parameters. If I comment out the demo code, mvn pmd:check fails because of the empty if block. If I leave the demo code unchanged, the build succeeds. Adding -Dpmd.verbose=true doesn't give a warning about the ignored file either. This might be a problem with the Maven plugin. At first I ran the code through a Sonarqube analysis (using the PMD plugin) where a warning about the ignored file appeared. Warning from Sonarqube analysis: [ERROR] [08:08:24.864] Fail to execute PMD. Following file is ignored: <DELETED>\Main.javanet.sourceforge.pmd.PMDException: Error while parsing <DELETED>\Main.java at net.sourceforge.pmd.SourceCodeProcessor.processSourceCode(SourceCodeProcessor.java:79) ~[pmd-core-5.4.0.jar:na] at net.sourceforge.pmd.SourceCodeProcessor.processSourceCode(SourceCodeProcessor.java:43) ~[pmd-core-5.4.0.jar:na] at org.sonar.plugins.pmd.PmdTemplate.process(PmdTemplate.java:82) ~[sonar-pmd-plugin-2.5.jar:na] at org.sonar.plugins.pmd.PmdExecutor.executeRules(PmdExecutor.java:120) [sonar-pmd-plugin-2.5.jar:na] Best regards, Arend |
