Build from source using Maven

Dependencies and requirements

Warning

CatBoost uses CMake-based build process since this commit. Previously Ya Make (Yandex's build system) had been used.

Select the appropriate build environment setup below accordingly.

Linux or macOS. Windows support in progress.
Set up build environment depending on build type:
- For CMake
- For Ya Make
Python. 3.6+
Maven 3.3.9+
JDK 8. Newer versions of JDK are not supported yet.

Set JAVA_HOME environment variable to point to the path of JDK installation
[Only for Ya Make] SWIG 4.0.2+

Cmake-based build uses SWIG from Conan packages so an explicit installation is not required.

Clone the repository:

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

Go to the catboost/catboost/spark/catboost4j-spark directory from the local copy of the CatBoost repository.
Run python ./generate_projects/generate.py to generate Maven projects for all supported Spark and Scala versions combinations.
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.
Use the usual maven build phases in these directories.
