Building steps

1. Clone the repository:

   git clone https://github.com/catboost/catboost.git
   

2. Go to the catboost/catboost/spark/catboost4j-spark directory from the local copy of the CatBoost repository.

3. Run python ./generate_projects/generate.py to generate Maven projects for all supported Spark and Scala versions combinations.

4. Go to the sub-directories ./projects/spark_<spark_compat_version>_<scala_compat_version> for spark_compat_version and scala_compat_version you are interested in.

5. Use the usual maven build phases in these directories.
