Associations to and from plugin

CakePHP 3.x
Hello everybody.
This is not the first time I get into trouble with plugin associations.
So I have Categories hasMany Articles => works fine
Articles hasMany Categories => works fine
Then
Articles hasOne plugin Boutique > Options => does not work
and plugin > Options belongTo Articles => does not work

Code for Articles table :
$this->hasMany(‘Formats’, [
‘foreignKey’ => ‘article_id’,
‘className’ => ‘Boutique.Articles’
]);
$this->hasMany(‘Options’, [
‘foreignKey’ => ‘article_id’,
‘className’ => ‘Boutique.Articles’
]);

All code (in models) comes from bake.
another example :
in options controller :
‘contain’ => [
‘Articles’ => [‘fields’ => [‘Articles.id’, ‘Articles.category_id’, ‘Articles.name’, ‘Articles.forsale’]],
‘Articles.Categories’ => [‘fields’ => [‘Categories.id’, ‘Categories.name’]],
‘Articles.Options’ => [‘fields’ => [‘Options.id’, ‘Options.article_id’, ‘Options.tva_id’]]
]
does not work either.

debugger says :
Articles is not associated with Categories
or Articles is not associated with Options
