JarAnalyzer Upgrade

Filed Under Architecture & Design, Java, Metrics, Platforms |  

I’ve updated JarAnalyzer to correct some of the problems reported when analyzing applications written on J2SE 5.0. The issues were primarily surrounding the use of Generics. If you’ve been experiencing any of the following problems when running JarAnalyzer 1.1, upgrading to JarAnalyzer 1.2 should make them go away and put you back on track.

  • You receive the following error at the console: Visiting non-standard Signature object. The fix required an upgrade to BCEL 5.2.
  • The xml output lists classes as Unresolved Dependencies. This problem was due to how JarAnalyzer strips the classname from the package the class belongs to.

A few other bug fixes and enhancements also found their way into version 1.2.

  • Used System properties file separator to increase portability across operating systems.
  • Updated filter.properties file to ignore packages you typically don’t want reported as Unresolved Dependencies. This can easily be modified before running JarAnalyzer if you want these to show in the output.

You can download the most current version of JarAnalyzer from the JarAnalyzer home.

    Is there a possibility to find out which
    jar caused the trouble?
    Got hundreds of
    “Visiting non-standard Signature object”
    messages analyzing a directory which contains the jars below. I am using version 1.2.

    Would be a very helpful tool if you could
    resolve the issue.

    Well that is interesting. I’ll try to look into this sometime soon (can’t promise anything). First thing you might want to check is that you are using the most current version of bcel (5.2).

    Kirk, you asked for some feedback on JarAnalyzer, so here are my few cents:

    - I like JAR Analyzer, the following features would be helpfull to me:

    - in the “UnresolvedDependencies” section not only list the names of the packages you did not found, but also the names of the packages or classes which used those

    - make all sections absent in the xml if empty

    - for the outgoing dependencies it would be interesting for me to differentiate the kind of usage. Especially “EI” (Extends Interface) and “EC” (Extends Class) and “EA” (Extends Abstract Class) would be interesting. This can be for example used to check that you are not extending any GPL’ed class:

    SomeGPL.jar

    …

    - would be good if JAR Analyser could traverse WAR/EAR/SAR archives

    - An ANT/Junit mode where i can specify assertions (like JDepend). So I can say “fail this build if any new dependency was added”. This is especially helpfull with the added features above.

    Greetings
    Bernd

    And work faster with dynamically updated cross-references, improved variable-data publishing, and automatic page addition and deletion. ,

    I know this is super old, and chances are you will not read this, but I’d love an optional report that tells you what the dependencies are caused by. I want to remove a particular jar file dependency, and find what needs it and remove it, and knowing Class X depends on jar Y, Class Z would be useful for removing jar Y.
