Multiple stacks.

Debug Output

Expected Behavior

I'm trying to see if I can use multiple stacks in multiple files like in CDK.
This is my current program

file1.ts

import {IamRole} from "./.gen/providers/aws";
import {TerraformStack} from 'cdktf'
import {Construct} from "constructs";


export class SecStack extends TerraformStack {
    constructor(scope: Construct, id: string) {
        super(scope, id);
        new IamRole(this, "cdk-tf-module-role", {
            name: "cdk-tf-module-role",
            assumeRolePolicy: JSON.stringify({
                "Version": "2012-10-17",
                "Statement": [
                    {
                        "Action": "sts:AssumeRole",
                        "Principal": {
                            "Service": "lambda.amazonaws.com"
                        },
                        "Effect": "Allow",
                    }
                ]
            })
        })
    }
}

file2.ts

import {Construct} from 'constructs';
import {App, TerraformOutput, TerraformStack} from 'cdktf';
import {AwsProvider, LambdaFunction, IamRole} from "./.gen/providers/aws";
import {SecStack} from "./role";

class MainStack extends TerraformStack {
    constructor(scope: Construct, id: string) {
        super(scope, id);

        new AwsProvider(this, "aws", {
            region: "eu-west-1",
        });

        const lambdaRole = new IamRole(this, "cdk-tf-lambda-role", {
            name: "cdk-tf-lambda-role",
            assumeRolePolicy: JSON.stringify({
                "Version": "2012-10-17",
                "Statement": [
                    {
                        "Action": "sts:AssumeRole",
                        "Principal": {
                            "Service": "lambda.amazonaws.com"
                        },
                        "Effect": "Allow",
                    }
                ]
            })
        })

        const lambda = new LambdaFunction(this, "cdk-tf-lambda", {
            filename: '../lambda/lambda.zip',
            functionName: 'cdk-tf',
            handler: 'index.handler',
            role: lambdaRole.arn,
            runtime: 'nodejs12.x'
        });

        new TerraformOutput(this, 'cdk-tf-lambda-arn', {
            value: lambda.arn
        });
    }
}

const app = new App();
new MainStack(app, 'dec-imp-main-stack');
new SecStack(app, 'dec-imp-sec-stack')
app.synth();

When cdktf deploy it appears that only the second stack is synth

Actual Behavior

The deploy is running forever (plan stage), it doesn't seem to work.

Steps to Reproduce

See program

I wonder if this duplicates - Handling of Multiple Stacks #35?

The examples there seem to be multiple stacks in one file, but here the example involves multiple files.
Sounds like the current recommendation is "dedicated folder per stack"

Yes , it looks like it is 👍

Sounds like the current recommendation is "dedicated folder per stack"

That's actually a good point and totally doable. The important part is, that the cdktf deploy/destroy command would run in separate folders to separate the stack output file and its state. Could be easily automated in a monorepo setup. Conceptually, that's pretty close how I think it'd be abstracted in the CLI as well.
