Building Xponents

After checkout, first build Core API (opensextant-xponents-core) Then you can begin working with the Tagger API (opensextant-xponents)

1. Setup project.


2. Setup Core API to build and test:

  (cd ./Core && mvn install)

3. Build SDK:

There are some outstanding build tasks related to gazetteer metadata assembly that need automation. But in general, you would make use of the ./solr/build.sh script and consult the README there.

  mvn install

4. Build a full Gazetteer from scratch.

./solr/README.md captures all the mechanics of building the Gazettter from checkout.

6. Distribution and Packaging: ant -f ./script/dist.xml dist

Producing API documentation updates: infrequently, only for major releases.

 cp -r target/site/apidocs/ doc/sdk-apidocs/
 cp -r Core/target/site/apidocs/ doc/core-apidocs/

 # When done, commit changes, as API docs appear on GitHub public site.

7. Test. Leverage the Examples projects to more fully test your build.

Level of Effort.

First time to acquire all the software and build could be a day: You would pull in 4 GB of compressed files, unpack them all, configure software, etc.
The Second time to walk through this all usually takes 2-4 hours, on a Macbook or Linux server with 4 CPU, for example.

If this sounds like a bit much, then leverage the artifacts in Maven Central or Docker Hub.

Maven Publishing

  # Fix all versions to be release versions.
  # Ensure GPG key is known...
  # and OSSRH login is set in settings.xml

  cd ./Core
  mvn clean deploy -P release
  cd ..
  mvn clean deploy -P release
