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.

Prerequisites

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:
```
PATH=<path_to_ant>/bin:<path_to_JDK>/bin:<klocwork_install>/bin:$PATH
```
- Windows:
```
PATH=<path_to_ant>\bin;<path_to_JDK>\bin;<klocwork_install>\bin;%PATH%
```

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

Usage

kwant <ant_options>

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

Options

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.
