I'm trying to make a simple Drupal installation profile compatible with D9. The project is
https://www.drupal.org/project/mandatory →
.
In the first step I've just added core_version_requirement to the *.info.yml file, in release 8.x-1.3:
name: Mandatory
type: profile
description: 'Build a custom site without any optional components (modules/themes)'
core: 8.x
core_version_requirement: ^8 || ^9
Then I've tried to test this by installing a D9 core:
composer create-project drupal/recommended-project:9.0.0-beta2 .
composer require drupal/mandatory
Result: while create-project worked, requiring the profile failed with multiple composer errors:
...
Using version ^1.3 for drupal/mandatory
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.
Problem 1
- Conclusion: remove drupal/core-recommended 9.0.0-beta2
- Conclusion: don't install drupal/core-recommended 9.0.0-beta2
- Conclusion: don't install drupal/mandatory 1.3.0
- Conclusion: remove doctrine/annotations v1.8.0
- Conclusion: don't install drupal/mandatory 1.3.0|remove drupal/core 9.0.0-beta2|install drupal/core 8.0.0|install drupal/core 8.0.0-beta10|install drupal/core 8.0.0-beta11|install drupal/core 8.0.0-beta12|...
Next thing I tried was restricting core version requirements to >= 8.7.7, in the current dev release:
name: Mandatory
type: profile
description: 'Build a custom site without any optional components (modules/themes)'
core_version_requirement: '^8.7.7 || ^9'
The result was similar:
Your requirements could not be resolved to an installable set of packages.
Problem 1
- Conclusion: remove doctrine/annotations v1.8.0
- Conclusion: don't install doctrine/annotations v1.8.0
- drupal/core 8.0.0 requires doctrine/annotations 1.2.* -> satisfiable by doctrine/annotations[v1.2.0, v1.2.1, v1.2.2, v1.2.3, v1.2.4, v1.2.5, v1.2.6, v1.2.7].
- drupal/core 8.0.0-beta10 requires doctrine/annotations 1.2.* -> satisfiable by doctrine/annotations[v1.2.0, v1.2.1, v1.2.2, v1.2.3, v1.2.4, v1.2.5, v1.2.6, v1.2.7].
- drupal/core 8.0.0-beta11 requires doctrine/annotations 1.2.* -> satisfiable by doctrine/annotations[v1.2.0, v1.2.1, v1.2.2, v1.2.3, v1.2.4, v1.2.5, v1.2.6, v1.2.7].
...
Finally I've added a composer.json file to the project:
{
"name": "drupal/mandatory",
"type": "drupal-profile",
"description": "Build a custom site without any optional components (modules/themes)",
"license": "GPL-2.0-or-later",
"homepage": "https://www.drupal.org/project/mandatory",
"support": {
"issues": "https://www.drupal.org/project/issues/mandatory",
"source": "https://cgit.drupalcode.org/mandatory"
},
"require": {
"drupal/core": "^8.7.7 || ^9"
}
}
Result: same problem.
I've tried the dev version of Drupal 9 core, too. No success.
Now I'm stuck a bit. I have no problems installing ported modules like e.g. Pathauto or Metatag, only this installation profile. Why does Composer try to check old Drupal releases like 8.0.0 given a version constraint of "^8.7.7 || ^9"? And is the Composer template drupal/core-recommended already compatible with Drupal 9? Or did I add a stupid typo? Help appreciated, thanks a lot!
