[BUG] Version incompatibility between direct usage of pylint-plugin-utils and indirect usage via pylint-django

[adamcunnington-mlg]

prospector 1.5.3.1 includes the following requirements:
pylint-plugin-utils=^0.6"
pylint-django=^2.4.4"

The trouble is that pylint-django 2.5.0 just got released and it pins pylint-django as follows:
pylint-plugin-utils>=0.7

Therefore, you cannot install prospector now without ending up with an incompatible version of pylint-plugin-utils.

You can easily replicate this by using a installation tool with proper dependency evaluation like pip-tools or poetry.

Suggested Fix

• Either explicitly pin prospector's dependency of pylint-django=2.4.4 (probably a good idea)
• Or Change the ^ dependency to be >= for prospector's requirement of pylint-plugin-utils (probably a bad idea)

Oops, sorry! pylint-plugin-utils==0.7 was a release to fix the concurrent job support in pylint-django, otherwise things are mostly the same.

Therefore I'll bump the requirement in prospector to ^0.7 and make a bugfix release.

Let's see if tests work and if so, I'll make a 1.5.4 prospector release.

Drat, pylint-plugin-utils has python>=3.6.2 and prospector >=3.6.1 (both of which will go away soon since pylint itself drops 3.6 support soon).

However that means it's a bit more than a bugfix release, so I think solution here is:

• release 1.5.4 with pylint-django = ~2.4.0 (just upgrade to 1.6)
• Also release 1.6 with newer versions of both pylint django, pylint plugin utils and drop support for python 3.6.1.

@adamcunnington-mlg 1.6.0 is on PyPI now with the proper version restrictions for those dependencies. Thanks for the report! I need to clean up this repository a bit :-)

@carlio same issue with 0.8 of pylint-plugin-utils now which is required by pylint-django 2.5.5
