Semanticmediawiki: composer shows errors and won't update dependencies

[tim1mike]

Setup

• SMW version: 3.2.2
• MW version: 1.35.1
• PHP version: 7.4.13
• DB system (MySQL, Blazegraph, etc.) and version: MariaDB 10.5.8

Issue

I've installed SMW with only one problem - version conflict with External Data 2.3 which required "symfony/css-selector": "~5.1" I just downgrade requirements to "^3.3"
Now it's working fine but I want to install more smw extensions so I add 3 new extensions into my composer.local.json

{
    "require": {
        "mediawiki/semantic-media-wiki": "~3.2",
        "mediawiki/semantic-result-formats": "~3.2",
        "mediawiki/semantic-breadcrumb-links": "~2.0",
        "mediawiki/semantic-meta-tags": "~3.0"
    },
    "extra": {
        "merge-plugin": {
            "include": [
                "extensions/*/composer.json",
                "skins/*/composer.json"
            ]
        }
    }
}

I ran composer update --prefer-source and then it showed some errors:

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

  Problem 1
    - Installation request for mediawiki/core No version set (parsed as 1.0.0) -> satisfiable by mediawiki/core[No version set (parsed as 1.0.0)].
    - mediawiki/semantic-result-formats 3.2.0 requires mediawiki/semantic-media-wiki ~3.0 -> satisfiable by mediawiki/semantic-media-wiki[3.2.2, 3.2.0, 3.2.1, 3.2.3].
    - remove mediawiki/core No version set (parsed as 1.0.0)|remove mediawiki/semantic-media-wiki 3.2.2
    - don't install mediawiki/semantic-media-wiki 3.2.0|remove mediawiki/core No version set (parsed as 1.0.0)
    - don't install mediawiki/semantic-media-wiki 3.2.1|remove mediawiki/core No version set (parsed as 1.0.0)
    - don't install mediawiki/semantic-media-wiki 3.2.2|remove mediawiki/core No version set (parsed as 1.0.0)
    - don't install mediawiki/semantic-media-wiki 3.2.3|remove mediawiki/core No version set (parsed as 1.0.0)
    - Installation request for mediawiki/semantic-result-formats ~3.2 -> satisfiable by mediawiki/semantic-result-formats[3.2.0].

I don't know why this is happening and can't install another extensions which required composer installation, I tried to find if I have mediawiki/core line somewhere but there's nothing found.
If I just remove "mediawiki/semantic-media-wiki": "~3.2", from composer.local.json it will remove SMW after composer update command.

I have many other extensions but seems they cause no problems with composer update at all

mediawiki/core? huh. I wonder where that is coming from

Dunno either. Perhaps try to remove the extra section and see what is happening after that.

Whoa it works, thanks!
Now I got some errors after maintenance/update.php but It's a solution!
I deleted "extensions/*/composer.json", and instead I added all the extensions one by one like this:

    "extra": {
        "merge-plugin": {
            "include": [
                "extensions/AWS/composer.json",
                "extensions/BetaFeatures/composer.json",
                "extensions/CategoryTree/composer.json",
                "extensions/Cite/composer.json",
                "extensions/CiteThisPage/composer.json"

Thanks for confirming my somehow educated guess. Note that you only have to include the "composer.json" files of extensions that fetch dependencies. All the rest is superfluous.
