It can be downloaded automatically by maven and placed into the local maven repository if you include the proper dependency in your maven project definition. Use groupId javax.jdo, artifactId jdo-api, version 3.0, and define your remote repository as Alternatively, it can be downloaded manually and put into a location of your choice.
  • The tck project contains the JDO Technology Compatibility Kit. The source distribution is the only artifact needed to be downloaded by the user.

All are available for download as source, but if you wish to run the TCK you need only download the TCK project. The dependencies will be automatically downloaded by maven as jar files.

For information on running the TCK, see TCK. If downloading multiple source packages, extract them all into the same directory. This will preserve the source dependencies among the projects.
