Conan-center-index: [service] Missing packages when creating packages in PRs

[danimtb]

When generating packages in PRs we have seen that some dependency packages are missing:

Affected ones reported are: #502 #498

The problem happened when generating the Clang 9 packages to close #211. We are running a custom build to generate the new packages and the hooks are not activated to avoid additional trouble.

However, the hook making this action https://github.com/conan-io/conan-center-index/wiki/Error-Knowledge-Base#kb-h031-conandatayml-reduce is not executed, and packages are exported with the complete contents of the conandata.yml file, generating a new recipe revision only with the clang 9 packages.

We have set the service under maintenance until the issue is solved

[danimtb]

The fix was merged but we are still running some test so the system will be under maintenance

[danimtb]

We found some recipe revision mismatches due to the reduction of the conandata.yml not being activated in the custom builds (internal builds).

There are some packages that have a wrong recipe revision due to this and should be regenerated before merging the clang 9 packages

The packages affected are the following:

['amqp-cpp/4.1.5',
 'b2/4.0.0',
 'benchmark/1.5.0',
 'cpp-sort/1.5.1',
 'eabase/2.09.05',

Packages were regenerated for the references above and merged to the central repository.

We will run again the test to check that the RREVs match and finally merge the clang 9 packages.

[danimtb]

Checks went OK and Clang 9 packages are ready to be merged now

[danimtb]

Clang packages are now merged to the central repo and available for consumers 🎉

This should not be an issue anymore. Disabling the "under maintenance" status...
