I have a GitHub project integrated with Travis.

Every time a commit is pushed, Travis tries to compile, and warn if it does not compile.

To take it further, I would like to integrate with a tool for static code analysis:

  • Find duplicate code
  • Find common probable bugs (recognizes the technology automatically, at least: Android, Java, C#)
  • Find package dependency cycles
  • Bonus: Run applicable off-the-shelf validation tools, for instance Lint for Android


  • Run analysis at every commit or at least on a regular basis
  • Free
  • Preferably a free (or free for open source projects) online service, installable (on-premise) if nothing else available.
  • Ideally, it would only require entering a Git URL.

I think SonarQube suits your needs, We use it exactly the same way you want but with jenkins and for java-based code(supports multiple languages though, no need to worry).
E.g. pushed a commit -> Jenkins builds and deploys -> updates SonarQube which gives online statistics. I imagine setting SonarQube with Travis wouldn't be too much trouble since it provides a lot of plugins for that reason.

UPDATE: Some plugins and general information for getting started with Jenkins and Sonarqube:

  • Here is the plugin for Jenkins+Github
  • Here is the plugin for Jenkins+SonarQube
  • Here is a link with further information about configuration of Jenkins+SonarQube
  • So setting up this requires to install Jenkins and SonarQube, the <a href="wiki.jenkins-ci.org/display/JENKINS/… Github and Jenkins</a>, then <a href="docs.codehaus.org/display/SONAR/… Jenkins and SonarQube</a>, right?

  • Yes Jenkins has this plugin for that reason. I haven't setted up myself but found many resources in a google search to get started. For github Jenkins offers(what a surprise) another plugin.

    @NicolasRaoul If you managed to get it working on Travis CI, then I would be interested to hear so. My main problem is how to publish the information somewhere.

  • @skiwi I, too, would like to integrate SonarQube with Travis CI, and still didn't find any solution. I would be ok to move to another CI tool, but I don't want to host or pay for anything, so Travis was nice. Did you find anything in the end?

  • @Joffrey No, I haven't looked further into this matter as far as I remember.

Coverity looks like what you want. I am starting to try it now for one of my projects but it seems promising.

Like does it match all or just some of Nicolas's requirements? Commented Jun 20, 2014 at 6:40
  • I looked into Coverity, but my main problem is that it cannot be triggered on pull-requests, which is a no-go for me. Also, I didn't find any way of customizing the rules for the scan, but maybe I just didn't dig enough.

I made Gradle and Maven plugins for that. It currently supports Findbugs, PMD, Checkstyle, CSSLint and JSHint, but support for more are planned. The result may look something like this:

Pull request in GitHub with static code analysis


For languages compiled by GCC (i.e. C++, C, Ada, Fortran, Go, D, ....) you could consider using a specialized MELT extension. (you'll probably need to code some MELT, depending on the analysis you want to do).

For C, you might also consider Frama C or Clang

  • The main requirement is "integrated with Github". Ideally, it would only require entering a hook address and maybe accepting an OAuth authentication.
