System.import doesn't look for file after build (Angular2)

I am currently using system.import to dynamically load a file at runtime to change environment variables.

This works great when I just use the ng service. I go to the file, change my environment variable here, and after refreshing the page, it changed my API urls.

Now I am trying to use it together with tomcat. I am creating an application and deploying to tomcat. It finds the file and builds fine, but when I change the file later, it doesn't update anymore, like when I did it locally using the ng service.

my code:

app.component.ts

ngOnInit()
{
    this.loadApiLinks();
}

loadApiLinks() {
    System.import('../../../deployment.ts').then(deployment=>{
        environment.API_ROOT = deployment.getApiRoot();
        environment.API_ENDPOINT = deployment.getApiEndpoint();
        this.isDataAvailable = true;
        console.log(environment.API_ROOT);
    });
}

      

        
        
        
      

    

My file is loading:

export enum Environment {
PRODUCTION,
ACCEPTANCE,
DEVELOPMENT,
LOCAL}
// Edit this variable to change the working environment
let environment: Environment = Environment.DEVELOPMENT;

let API_ROOT_ACC: string = "https://hi02549:8080/campus_acceptance";
let API_ENDPOINT_ACC: string = "https://hi02549:8080/campus_acceptance/api/";

let API_ROOT_DEV: string = "https://hi02549:8080/campus";
let API_ENDPOINT_DEV: string = "https://hi02549:8080/campus/api/";

let API_ROOT_LOCAL: string = "http://localhost:8080/campus";
let API_ENDPOINT_LOCAL: string = "http://localhost:8080/campus/api/";

export function getApiRoot() {
    switch(environment) {
        case Environment.ACCEPTANCE:
            return API_ROOT_ACC;
        case Environment.DEVELOPMENT:
            return API_ROOT_DEV;
        case Environment.LOCAL:
            return API_ROOT_LOCAL;
        default:
            return null;
    }
}

export function getApiEndpoint() {
    switch(environment) {
        case Environment.ACCEPTANCE:
            return API_ENDPOINT_ACC;
        case Environment.DEVELOPMENT:
            return API_ENDPOINT_DEV;
        case Environment.LOCAL:
            return API_ENDPOINT_LOCAL;
        default:
            return null;
    }
}

      

        
        
        
      

    

Does System.import work differently than I thought? Or what am I doing wrong? I've already tried to insert the file wherever I could.
