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

To build and use DITA-OT, you’ll need:

• Java Development Kit 8 or newer

1. Clone the DITA-OT Git repository:

    git clone git://github.com/dita-ot/dita-ot.git
   

2. Move to the DITA-OT directory:

    cd dita-ot
   

3. Fetch the submodules:

    git submodule update --init --recursive
   

4. In the root directory, run Gradle to compile the Java code and install plugins:

    ./gradlew
   

1. Run the dita command to generate output:

    src/main/bin/dita [options]
   

   See the documentation for arguments and options.

1. In the root directory, set up build environment:

    ./gradlew
   

2. Build distribution packages:

    ./gradlew dist
   

   Distribution packages are built in the build/distributions directory.

   If Gradle throws an error like java.lang.OutOfMemoryError: Java heap space, you probably need to increase the maximum Java heap size. One way to do this is to set the GRADLE_OPTS environment variable to a value like -Xmx1024m.

   For more information on the -Xmx option, see Java SE Documentation.
