Install Tasks runs every time

See original GitHub issue

It seems like this plugin doesn’t take advantage of gradle’s incremental build system very well.

Even when there have been no changes to the list of dependencies the plugin seems to consistently install dependencies that were loaded by the last build.

Good eyes. Thats exactly what im seeing. Shouldn’t gradle’s dependency resolution automatically pick the latest version or are these really two different configurations? I would think each configuration would have their own venv tho, thats kinda the point of configurations, to break the project up into modules.

  Build cache is disabled
Task ':common:installBuildRequirements' is not up-to-date because:
  **Task has not declared any outputs despite executing actions.**

https://docs.gradle.org/4.0/userguide/more_about_tasks.html#sec:up_to_date_checks

What this means for build authors is simple: you need to tell Gradle which task properties are inputs and which are outputs. If a task property affects the output, be sure to register it as an input, otherwise the task will be considered up to date when it’s not. Conversely, don’t register properties as inputs if they don’t affect the output, otherwise the task will potentially execute when it doesn’t need to. Also be careful of non-deterministic tasks that may generate different output for exactly the same inputs: these should not be configured for incremental build as the up-to-date checks won’t work.
