Description

TsMorphMetadataProvider does not discover entities when using import with paths relative to the baseUrl :

import {Organization} from "src/entities/organization.entity";

instead of

import {Organization} from "./organization.entity";

How to reproduce

npm run mikro:cache:generate

outputs :

> mikro-orm-v6@1.0.0 mikro:cache:generate
> mikro-orm cache:generate

Generate metadata cache

Options:
--config         Set path to the ORM configuration file           [string]
--ts-node, --ts  Use ts-node to generate '.ts' cache             [boolean]
-c, --combined       Generate production cache into a single JSON file that
can be used with the GeneratedCacheAdapter.
-v, --version        Show version number                             [boolean]
-h, --help           Show help                                       [boolean]

}

We add these lines in the initSourcesFiles function in TsMorphMetadataProvider :

const diagnostics = this.project.getPreEmitDiagnostics()
console.log(this.project.formatDiagnosticsWithColorAndContext(diagnostics))

We get the following output :

> mikro-orm-v6@1.0.0 mikro:cache:generate
> mikro-orm cache:generate
