This is actually the JSPWiki build file. If you want to have the most recent version, you can get the source package.

If you are using a similar structure in your own project, you should be able to just take this file and change some values of some of the properties in the beginning of the file.

    This is the Ant build file for the JSPWiki project.

    The verbosity in this file is intentional - it is also
    an example for those who don't know Ant yet that well
    and would like to learn it.

    The build file assumes the following directory structure:

    JSPWiki
    |___build.xml
    |  
    |___etc
    |   |___[jspwiki.properties and other misc files]
    |          
    |___src     
    |   |___webdocs
    |   |   |___[all .jsp files]
    |   |   |___WEB-INF
    |   |       |___web.xml [the deployment file]
    |   |       
    |   |___com 
    |       |___[...and the rest of the source code files]
    |          
    |___tests   
        |___com 
            |___[...and the rest of the test source code]

       that compile every .java file in ${code.src} into .class files
       in directory ${code.build}.  The is no debugging information
       and the compiler is instructed to optimize the resulting code.

       "path.base" -->

       not ask for a password when you're checking it out.

  <!-- Running tests -->

  <!-- This target runs the JUnit tests that are available
       under tests/.  It generates the test result files
       into the ${tests.reports} -directory, one file per
       each tested class.  The tests are generated in
       plain text, but you can easily get XML format results
       as well, just by setting the formatter, below.

       Only tests that end with "*Test.java" are included.
       This is because then you can also use a manual
       "AllTests.java" in each directory, as per the JUnit
       Cookbook.

       This runs the tests in text mode.  If you want the
       pretty GUI you probably want to write a new target.
