Python Gradle Plugin

Now, all what is required to run python scripts is Java.

This Gradle Plugin uses Miniforge to run executables (python, pip, conda etc.) from virtual env.

Python project configuration can be fully automated by Gradle tasks.

Requirements

Java JDK or JRE version 8 or higher

Purpose

Running python scripts or projects by executing single tasks which will download and install Python virtual environment.

Additional Python configuration (pip/conda packages installation etc.) can be done by defining Gradle tasks in build.gradle.kts file.

Usage

Steps to run python script from Gradle

Apply a plugin to a project as described on gradle portal.
Configure a plugin by specifying desired python version in build script:
```
pythonPlugin {
    pythonVersion.set("3.8.2")
}
```
Possible properties in plugin extension are:
- pythonVersion -> Python environment version, default 3.10.4
- miniforgeVersion -> Miniforge3 version, default latest

Define a task to run desired python script, for example to run quicksort.py script in main dir add the following task configuration to build script:

tasks {
    register<VenvTask>("runQuickSort") {
            workingDir = projectDir.resolve("main")
            args = listOf("quicksort.py")
    }
}

Run python script from gradle:

# Linux
./gradlew runQuickSort
# Windows
gradlew.bat runQuickSort

Enjoy ?

Additional examples alongside with sample PipTasks configurations can be found in `examples` module in this project.

Intellij setup

To have autocomplete and modules properly recognized in Intellij Idea simply point python executable as described in: https://www.jetbrains.com/help/idea/configuring-python-sdk.html
To have properly recognized imported source modules in tests, right click on sources directory (for example main) -> Mark Direcotry as -> as Sources root.

Python exec locations (`*` is a configured python version)

Linux – `.gradle/python/pythonVenvs/virtualenv-*/bin/python`

Windows – `.gradle/python/pythonVenvs/virtualenv-*/Scripts/python.exe`

Notes

It may be required to unset PYTHONPATH in system before running any tasks (https://stackoverflow.com/a/31841132)
