Angular11升级后fileReplacements功能失效问题求助

我们团队将应用的Angular版本从10.2.3升级至11.2.19（@angular/cli），此前正常工作的fileReplacements环境文件替换功能现已失效。经测试发现，当@angular-devkit/build-angular版本为0.1002.3时替换功能恢复正常，但使用Angular升级推荐的0.1102.18及以上版本时无法实现替换，我们已测试了0.1002.3至0.1102.19间的所有版本。

我们预期构建时能将environment.json替换为对应环境的文件（如environment.dev-machine.json），但实际未发生替换。
