The kwant command creates a Java build specification based on the information in your ant build file. The kwant command intercepts the invocation of the javac task, and generates a build specification, which can then be used to analyze a Java project.


Before you can create a build specification, you need to:

  • install the Server package. See Installing Klocwork.
  • install Ant. See Supported Java build tools to see what versions are supported.
  • JAVA_HOME, JDK_HOME and PATH environment variables must be configured with the same values as your Ant build. Below is an example for PATH:
    • Unix:
    • Windows:
    • PATH=<path_to_ant>\bin;<path_to_JDK>\bin;<klocwork_install>\bin;%PATH%

For how-to information, see Creating a Java build specification.


kwant <ant_options>

where <ant_options> are any arguments required for your ant build


Name (and short name) Description
--help (-h) display help
--version display kwant version
--output <file> (-o) write the build specification to <file>. By default, the build specification is written to kwinject.out in the current working directory.
--update (-u) when specified, the existing build specification is updated with the results of the new incremental build instead of overwriting it.
