One particular scenario where this was causing problems was when the [BackupFileCleaner][1] restored a file (such as a `.d.ts` file) by [moving the backup file][2] to its original location, but the modified content was kept in the cache.

/**
|
|
* **Usage:**
|
|
* ```sh
|
|
* node mock-ngcc-version-marker <entry-point> <mock-ngcc-version>
|
|
*
|
|
* # Example:
|
|
* # node mock-ngcc-version-marker @angular/material/button 3.0.0
|
|
* ```
|
|
*
|
|
* Ngcc marks entry-points as processed by adding marker properties in their `package.json`. It uses
|
|
* a version as a marker in order to be able to distinguish entry-points processed by a different
|
|
* ngcc version (e.g. an older version after an update) and perform the necessary clean-up.
|
|
*
|
|
* This script replaces the ngcc version marker in an entry-point's `package.json` to make it appear
|
|
* as if it were processed by a different version of ngcc. This allows testing the clean-up logic
|
|
* without the overhead of actually installing a different ngcc version, compiling the dependencies,
|
|
* then installing the current version and compiling again.
