NPE: Preconditions.checkNotNull

[dajester2013]

I'm getting an NPE running sonar-scanner with the following properties:

The problem goes away if I remove the exclusions. I have a feeling I've got a bad exclusion, but I'm not sure how to write it properly. If that is the case, it should throw a useful exception stating as such, not an NPE.

Sonar properties:

# must be unique in a given SonarQube instance
sonar.projectKey=redacted
# this is the name and version displayed in the SonarQube UI. Was mandatory prior to SonarQube 6.1.
sonar.projectName=redacted
sonar.projectVersion=1.0
 
# Path is relative to the sonar-project.properties file. Replace "\" by "/" on Windows.
# This property is optional if sonar.modules is set. 
sonar.sources=modules,library,components

sonar.exclusions=**/*.java,**/*.class,**/extjs*/**/*,**/build/**/*
sonar.java.binaries=.
# Encoding of the source code. Default is default system encoding
#sonar.sourceEncoding=UTF-8

NPE Exception trace:

BTW, the java stuff is in there to get it to play nicely with the TFS SonarQube plugin - it's irrelevant otherwise.

We had similar reports in the past with #6, and those weren't related to any exclusions -- at least none of the examples reported there had any.

It looks like a paths problem. Specifically, the code that parses CFLint's XML output is trying to get a handle on the file for a given issue and most likely isn't finding it in the index of files of the sonar-scanner.

What could help is, if you could attach here:

• the console output of your sonar-scanner, preferably after running it with --debug
• the XML file output by CFLint (you'll find it at .scannerwork/cflint-result.xml inside the directory where you run sonar-scanner)
• the structure of your code -- where your sonar-project.properties sits, vs. where the code is, and what's the working directory you're running sonar-scanner from.

I'm running into the same issue scanning a reasonably large project. Unfortunately I can't share results because it's corporate code, but here's the stack trace:

Additional info: I was able to run CFLint successfully against Cold Fusion code that (one project) won't finish a Sonar scan without NPE: Preconditions.checkNotNull, and (another project) that scans into Sonar OK but doesn't let you drill down into the detailed issues - it shows zeros for each of the blocker, critical, major, minor and info issues, which doesn't match up with the summary stats.
