Gradle, the build workhorse from the Java ecosystem, extends its support to Python through Pygradle. A recent attempt to build a Python-3.x project using Pygradle though did't work as expected.
The delta between the supported Python-2.x vs Python-3.x is hard to reconcile with many issues like:
- Need for a specific, old version of Java (ver.8), Gradle (ver. 5.0), etc
- Dependencies on old versions of Python modules without backwards compatibility
- Hard to figure out which exact version will work
- A rule of thumb is to pick the highest version dependency module around some cut-off year like 2018/19, post which they don't seem to build
- Downloading of the correct dependencies & creating ivy files
- Includes identifying the right version, name, dependencies-within-dependencies (that no longer work on Python-3.x), etc.
- Using a local file system based repo to download & build modules & ivy files
With some effort though, have been able to complete a successful build on a Python-3.8 on an Ubuntu-20.04 with Java-8 & Gradle-5.0. More details are available on the pygradle_python3_example repo. Hope this helps!
