PMD is currently not working properly for Java classes that use [unnamed packages](https://docs.oracle.com/javase/specs/jls/se11/html/jls-7.html#jls-7.4.2). Consider the following Java class that does not contain a `package` declaration: ```java public class App { String getGreeting() { return "Hello world."; } static void main(String... args) { System.out.println(new App().getGreeting()); } } ``` Running PMD in the command line agaist the Java class above produces an output with empty string `""` in the `"Package"` column: ```sh $ pmd -R category/java/bestpractices.xml -f csv -d './src/main/java/App.java' Oct 02, 2018 9:10:39 PM net.sourceforge.pmd.PMD processFiles WARNING: This analysis could be faster, please consider using Incremental Analysis: https://pmd.github.io/pmd-6.7.0/pmd_userdocs_incremental_analysis.html "Problem","Package","File","Priority","Line","Description","Rule set","Rule" "1","","/Users/diego/Projects/github.com/dlresende/kata-fizz-buzz/src/main/java/App.java","2","7","System.out.println is used","Best Practices","SystemPrintln" ``` But the pmd.vim handler's current pattern refuses everything coming from a Java class that does not have a package name (2nd column): ```vim let l:pattern = '"\(\d\+\)",".\+","\(.\+\)","\(\d\+\)","\(\d\+\)","\(.\+\)","\(.\+\)","\(.\+\)"$' ``` The solution I am proposing is to also accept empty strings as package names.
