Spring не разрешает # {systemEnvironment ['NAME']} в application.yml

Когда я указываю простой абсолютный путь в application.yml, все работает, но когда я пытаюсь заменить домашний каталог проекта значением переменной среды, он не работает.

spring:
  profiles:
    active: native
  cloud:
    config:
      discovery:
        enabled: true
      server:
        native:
#          searchLocations: file:#{systemEnvironment['PROJECT_HOME']}/backend/cloud-config/{application}
          searchLocations: file:/temp/pets/backend/cloud-config/{application}

Во время выполнения неразрешенное значение (file:#{systemEnvironment['PROJECT_HOME']}/backend/cloud-config/some-service) передается в org.springframework.cloud.config.server.environment.NativeEnvironmentRepository#getLocations, и 

if (isDirectory(value)) {
    output.add(value);
}

, очевидно, isDirectory(value) возвращает false, и в конечном итоге spring.config.location= в Spring становится пустым.

PS:
Используется: spring-cloud-config-server-1.2.2.RELEASE

SpEL не поддерживается в application.yml;вы можете, однако, использовать свойства заполнителей.Используйте ${PROJECT_HOME:unspecified}/... (где unspecified будет использоваться, если переменная окружения не установлена.
