[bug] Dependencies are now forced to be built from source

Hello,

Thank you for taking the time to read my issue.

Context

We have been using Conan to build packages for our CPP projects (with GitHub Actions), and since today, we had no problem.

We have implemented a CI with Conan and GitHub Actions, in order to trigger a build every time a commit is pushed on our main branches.

Yesterday, we merged a pull request that triggered a build for one of our project, and the build lasted for around 1 minute. We have added a cache for dependencies, so 1 minute is a normal time for this project.

Problem

Today, we decided to re-run the build on GitHub Actions manually for the same commit, and this time it took around 4 minutes. By reading the logs, we found out that our dependencies were forced to be built from source.

After running other projects that use the Conan and GitHub Actions integration, all of our builds are taking way too much time, because they are forced to build our dependencies from source (from 3 minutes to 25 minutes).

Additional test to confirm the problem

We decided to run a new docker container with an Ubuntu 18.04 image, and tried to build one of our projects.

Here is a part of the log we got:

protobuf/3.9.1@bincrafters/stable: Forced build from source
srp/0.19@uavia/stable: Forced build from source
boost/1.69.0@conan/stable: Forced build from source

Dependencies are also forced to be built from source, even if they are in the ./conan/data.

Environment Details

• Operating System+version: Ubuntu 18.04 (under GitHub Actions)
• Compiler+version: GCC 7
• Conan version: 1.26
• Python version: 3.7.7

Logs

(1) The build from yesterday on GitHub Actions printed this:

Question

Why our dependencies are now forced to be built from source, instead of using the already installed versions ?

[maxime-uavia]

I updated the CPT package to 0.33.2 and it works like a charm, thank you !

[patpir]

Hi, @maxime-uavia are you using Conan Package Tools in your build?

Because we are seeing the same problem, but only with the latest version of Conan Package Tools (0.33.1), and it doesn’t happen after switching back to Conan Package Tools 0.33.0.
