The DITA Open Toolkit, or DITA-OT for short, is an open source tool that provides processing for OASIS DITA content. See dita-ot.sf.net for documentation, information about releases, and download packages.

In order to build and use DITA-OT, you’ll need:

• Java Development Kit 6 or newer

• Apache Ant 1.8.2 or newer.

  Please note that if you receive errors like unknown protocol: plugin or unknown protocol: cfg then you may have some missing libraries from your ant installation. In that case please download a recent distribution of ant and use that instead.

1. Clone DITA-OT Git repository.

2. On root directory, compile Java code:

    ant jar
   

3. Make sure the following files and directories are added to your CLASSPATH system variable:

   • src/main/lib/

4. Run plug-in installation:

    ant -f src/main/integrator.xml
   

1. Add the following files and directories to CLASSPATH system variable:

   • src/main/
   • src/main/lib/
   • src/main/lib/dost.jar
   • src/main/lib/xercesImpl.jar
   • src/main/lib/xml-apis.jar
   • src/main/lib/commons-codec-1.4.jar
   • src/main/lib/saxon/saxon9-dom.jar
   • src/main/lib/saxon/saxon9.jar
   • src/main/lib/resolver.jar
   • src/main/lib/icu4j.jar

2. Change directory to src/main.

3. Run DITA-OT with:

    ant [options]
   

   See documention for arguments and options.

1. On root directory, compile Java code:

    ant jar
   

2. Add the following files and directories to CLASSPATH system variable:

   • src/main/
   • src/main/lib/
   • src/main/lib/dost.jar
   • src/main/lib/xercesImpl.jar
   • src/main/lib/xml-apis.jar
   • src/main/lib/commons-codec-1.4.jar
   • src/main/lib/saxon/saxon9-dom.jar
   • src/main/lib/saxon/saxon9.jar
   • src/main/lib/resolver.jar
   • src/main/lib/icu4j.jar

3. Run plug-in installation:

    ant -f src/main/integrator.xml
   

4. Build distribution packages:

    ant dist
   

   Distribution packages are build into target directory.

   On some systems you may encounter an java.lang.OutOfMemoryError: Java heap space. In that case you need to provide more memory to the ant process. One way of doing that is by setting the ANT_OPTS system variable to specify more memory, for example setting that to -Xmx1000m should be enough.
