The order of entries in project references make initial build fail or pass

[Bnaya]

TypeScript Version: ^3.7.0-dev.20191011

Search Terms: composite project build references

I'm working on making react-admin being built as a composite project WIP PR
I'm making use of allowJS, decelerations, composite
disclaimer: i'm not a maintainer there

On the first build of a project (as in ci without build cache) the build might fail, depends on the order of entries in the references entry.
With error:

Cannot find module 'xxx'.

For example, this tsconfig fails with Cannot find module 'ra-core'
Code

{
    "references": [
        { "path": "packages/ra-tree-ui-materialui" },
        { "path": "packages/ra-core" },
        { "path": "packages/ra-i18n-polyglot" },
        { "path": "packages/ra-ui-materialui" },
        { "path": "packages/react-admin" },
        { "path": "packages/ra-data-fakerest" },
        { "path": "packages/ra-data-graphcool" },
        { "path": "packages/ra-data-graphql" },
        { "path": "packages/ra-data-graphql-simple" },
        { "path": "packages/ra-data-json-server" },
        { "path": "packages/ra-data-simple-rest" },
        { "path": "packages/ra-input-rich-text" },
        { "path": "packages/ra-realtime" },
        { "path": "packages/ra-tree-core" }
    ],
}

But

{
    "references": [
        { "path": "packages/ra-core" },
        { "path": "packages/ra-i18n-polyglot" },
        { "path": "packages/ra-ui-materialui" },
        { "path": "packages/react-admin" },
        { "path": "packages/ra-data-fakerest" },
        { "path": "packages/ra-data-graphcool" },
        { "path": "packages/ra-data-graphql" },
        { "path": "packages/ra-data-graphql-simple" },
        { "path": "packages/ra-data-json-server" },
        { "path": "packages/ra-data-simple-rest" },
        { "path": "packages/ra-input-rich-text" },
        { "path": "packages/ra-realtime" },
        { "path": "packages/ra-tree-core" },
        { "path": "packages/ra-tree-ui-materialui" }
    ]
}

pass.

Running the build again making it pass.

Repro (Sorry, its not very minimal)
pull the following branch: https://github.com/Bnaya/react-admin/tree/allowjs-plus-declarations
yarn; yarn cleanup; yarn build-with-composite

[sheetalkamat]

This seems to be happening because of shared module resolution cache between projects..

When building `10:39:56 AM - Building project 'c:/temp/react-admin/packages/ra-tree-ui-materialui/tsconfig.json'...` the `ra-core` module is resolved as not present and that information is saved. And error isn't reported because it is from `.js` file without ts-check enabled?

Building again it builds because its not using module resolution cache

In short your project references are nor representing real truth of dependencies and because errors are suppressed in some cases you dont see them.

TBH i'm not sure if i've understand,
Why won't it build ra-core when it can't find it?

[sheetalkamat]

Because ra-tree-ui-materialui does not have project reference to ra-core that tells that ra-core needs to be built before it.

I've understood my problem
Thank you!
