What

platforms is hardcoded as the directory the native projects are generated into. This makes it configurable:

// nativescript.config.ts
export default {
  buildPath: "build/native",
} satisfies NativeScriptConfig;

Defaults to platforms, so a project that does not set it behaves exactly as before.

How

ProjectData.platformsDir is derived from a new getBuildRelativeDirectoryPath(), which reads buildPath from the project config. nsConfig is now assigned before platformsDir in initializeProjectData so the value is available when the directory is computed.

Everything that already goes through projectData.platformsDir follows along for free. The four places that reached for the PLATFORMS_DIR_NAME constant to name the project's own build directory were switched to the new method:

  • ns clean
  • ns migrate (the pre-migration cleanup)
  • ns update (the pre-update cleanup)
  • ns typings android (locating dts-generator.jar)

The platforms folder inside a plugin's own npm package is a different thing entirely — plugins-service and ns plugin build keep using the constant for it.

Tests

npm test — 1858 passing. Added coverage in test/project-data.ts for the default and for a configured buildPath, asserting both the relative path and the resolved platformsDir.

Notes

From https://github.com/Akylas/nativescript-cli. Independent of #6129 and #6130; #6129 adds a getBuildRelativeDirectoryPath() computed from platformsDir, which this PR replaces with the config-backed version — whichever lands first, the other needs a one-method merge.

Summary by CodeRabbit

  • New Features
    • Added support for configuring a custom native-project build directory.
    • The build directory defaults to platforms when no custom path is provided.
  • Bug Fixes
    • Cleanup during project updates and migrations now targets the configured build directory.
    • Android type generation uses the configured native-project location.
  • Tests
    • Added coverage for default and custom build-directory configurations.

`platforms` was hardcoded as the directory the native projects are
generated into. A project can now point it somewhere else with
`buildPath` in `nativescript.config`:

```js
export default {
  buildPath: "build/native",
} satisfies NativeScriptConfig;
```

`ProjectData.platformsDir` is derived from it, so everything that already
goes through `platformsDir` follows along. The places that reached for
the `platforms` constant to talk about the project's own build directory
- `ns clean`, `ns migrate`, `ns update` and `ns typings android` - now
ask `getBuildRelativeDirectoryPath()` instead. The `platforms` folder
inside a plugin's own package is unrelated and untouched.

Defaults to `platforms`, so nothing changes for a project that does not
set it.

Review Change Stack

📝 Walkthrough

Walkthrough

The project now supports an optional buildPath setting. ProjectData resolves the configured path or defaults to platforms. Cleanup and Android typings lookup use the resolved build directories.

Changes

Build path configuration and resolution

Layer / File(s) Summary
Build path contract and resolution
lib/constants.ts, lib/definitions/project.d.ts, lib/contracts/project-data.ts, lib/project-data.ts, test/project-data.ts
INsConfig supports buildPath. ProjectData exposes getBuildRelativeDirectoryPath() and derives platformsDir from the configured or default path. Tests cover both cases.

Build path consumers and cleanup

Layer / File(s) Summary
Build path consumers and cleanup
lib/commands/clean.ts, lib/commands/typings.ts, lib/controllers/..., test/controllers/update-controller.ts, test/stubs.ts
Cleanup targets the build-relative directory. Android typings lookup uses platformsDir. Test project-data implementations provide the new method.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 8a191

Configurable build paths are added, but the current change may contain a duplicate type declaration that blocks compilation and may allow cleanup commands to operate outside the project directory when given an escaping path. These issues should be verified and addressed or explicitly accepted before merge; the remaining stale error message is minor.

Poem

I hop through paths where platforms grew,
Now buildPath tells me where to chew.
Cleanup follows the chosen trail,
Typings finds its tools without fail.
A tidy burrow, defaults in view—
The rabbit approves this change anew.

Use a build-directory message for custom buildPath.

When the generator is missing, Line 170 still reports "No platforms folder found". This is incorrect for configurations such as buildPath: "build/native". Report the configured build directory or use a generic native build directory message.

⚠️ Unverified finding
Sandbox verification was unavailable.

Remove the duplicate buildPath declaration.

INsConfig declares buildPath?: string at Line 198 and again at Line 216 in the same interface. This produces a TypeScript duplicate-identifier error and can block the build. Keep the documented property at Line 198 and remove the copy from the legacy-key block.

⚠️ Unverified finding
Sandbox verification was unavailable.

Define and enforce a project-root boundary for buildPath.

getBuildRelativeDirectoryPath() returns the raw configuration value. ns clean, ns migrate, and ns update pass this value to cleanup. A value such as ../../outside can escape the project root if cleanup joins relative paths without containment checks. Reject escaping paths, or verify that IProjectCleanupService.clean enforces this boundary.
