Plugin breaks when composer.phar is not in the root directory of a project

[NobleUplift]

I have to have composer.phar nested deep within the src directory of my project. Because of this, Composer PHP Support believes the composer.phar is missing.

It should look for composer.phar in the same directory that the composer.json resides in.

[As I understand your issue] — there are an option in Preferences → Composer → Composer binary.
You can select Use global composer and set your custom version of it in Custom composer binary field.

Thanks! We recently changed our architecture concerning Composer, so I'll have to look into this again.
