Affects PMD Version:
6.0.1
Rule:
Description:
When supplying a file list and requesting display of short names, the parameter inputFileName to the function FileDataSource.glomName is unset, thus causing NullPointerException at line 40:
if (shortNames && inputFileName.indexOf(',') == -1) {
The inputFileName parameter is passed with configuration.getInputPaths() (AbstractPMDProcessor.java:57). The inputPaths field of configuration is set to null because there is no --directory parameter passed on the command line. But passing this parameter will cause all source files under the directory to be included rather than just the files specified in file list.
Code Sample demonstrating the issue:
