Problem with dependency in 2.6.* & 2.7.* series

[esteban-serfe]

The MFTF suite will not install thorugh composer as dependencies have conflicts on the versions.

Preconditions

• Magento Enterprise Edition 2.3.6

Steps to reproduce

1. Run compose require -dev magento/magento2-functional-testing-framework:2.6.*

Expected result

1. Have MFTF installed

Actual result

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for doctrine/inflector (locked at 1.4.3) -> satisfiable by doctrine/inflector[1.4.3].
    - magento/magento2-functional-testing-framework 2.6.0 requires csharpru/vault-php ~3.5.3 -> satisfiable by csharpru/vault-php[3.5.3].
    - magento/magento2-functional-testing-framework 2.6.1 requires csharpru/vault-php ~3.5.3 -> satisfiable by csharpru/vault-php[3.5.3].
    - magento/magento2-functional-testing-framework 2.6.2 requires csharpru/vault-php ~3.5.3 -> satisfiable by csharpru/vault-php[3.5.3].
    - magento/magento2-functional-testing-framework 2.6.3 requires csharpru/vault-php ~3.5.3 -> satisfiable by csharpru/vault-php[3.5.3].
    - magento/magento2-functional-testing-framework 2.6.4 requires csharpru/vault-php ~3.5.3 -> satisfiable by csharpru/vault-php[3.5.3].
    - magento/magento2-functional-testing-framework 2.6.5 requires csharpru/vault-php ~3.5.3 -> satisfiable by csharpru/vault-php[3.5.3].
    - magento/magento2-functional-testing-framework 2.6.6 requires csharpru/vault-php ~3.5.3 -> satisfiable by csharpru/vault-php[3.5.3].
    - csharpru/vault-php 3.5.3 requires doctrine/inflector ~1.1.0 -> satisfiable by doctrine/inflector[v1.1.0].
    - Conclusion: don't install doctrine/inflector v1.1.0
    - Installation request for magento/magento2-functional-testing-framework 2.6.* -> satisfiable by magento/magento2-functional-testing-framework[2.6.0, 2.6.1, 2.6.2, 2.6.3, 2.6.4, 2.6.5, 2.6.6].


Installation failed, reverting ./composer.json to its original content.
```

Same happens without requiring an specific version.

@EstebanSerfe
We have been running/testing release packages in composer builds.

Can you try to update to latest MFTF 2.6.x for Magento 2.3.6? or latest MFTF 2.7.x for Magento 2.3.7?

Hi @jilu1
Thanks for your response.

We are not using Magento Commerce 2.3.7 with PHP 7.3 and Composer 1
Trying to install MFTF 2.7.1 manually gives me the following conflict:

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Can only install one of: doctrine/inflector[v1.1.0, 1.4.4].
    - Can only install one of: doctrine/inflector[v1.1.0, 1.4.4].
    - Can only install one of: doctrine/inflector[v1.1.0, 1.4.4].
    - csharpru/vault-php 3.5.3 requires doctrine/inflector ~1.1.0 -> satisfiable by doctrine/inflector[v1.1.0].
    - magento/magento2-functional-testing-framework 2.7.1 requires csharpru/vault-php ~3.5.3 -> satisfiable by csharpru/vault-php[3.5.3].
    - Installation request for magento/magento2-functional-testing-framework 2.7.1 -> satisfiable by magento/magento2-functional-testing-framework[2.7.1].
    - Installation request for doctrine/inflector (locked at 1.4.4) -> satisfiable by doctrine/inflector[1.4.4].

I see the following modules having doctrine/inflector as dependencies on my composer.lock file:

• Elasticsearch/elasticsearch: ^1.3 on require-dev => ?? might be in conflict?
• illuminate/support: ^1.1 => OK

Is this an issue with some other package that have the dependency also to doctrine/inflector that is not been mentioned on the conflict listing?

Doing some research, on Version 4.0.1 of csharpru/vault-php the dependency is updated to 1.3 and on higher version is removed. See https://github.com/CSharpRU/vault-php/blob/4.0.1/composer.json & https://github.com/CSharpRU/vault-php/blob/develop/composer.json

[esteban-serfe]

found that the module elasticsearch/elasticsearch removed the dependency 13 days ago from require dev. See elastic/elasticsearch-php@ff65e31

Trying updating the module to newest version. 🤞🏻

Finally solved my issue doing:

composer update elasticsearch/elasticsearch
compsoer require --dev doctrine/inflector:1.1.*
composer require --dev magento/magento2-functional-testing-framework:2.*

Seems that the elastic search version had doctrine/inflector locked into 1.4.4 and prevented the install that way.
Adding the second command downgraded the vesrion to 1.1.* which allowed to install 2.7.1 into the environment.

Not the best solution but did the trick.
