VS 代码扩展：所有定义的任务都使用 vscode.CustomExecution return 最后定义任务的结果

Question

进入

我创建了一个简单的 VS 代码扩展，它定义了多个任务：

ExamplePseudoterminal1 Task 1, ExamplePseudoterminal1 Task 2, ExamplePseudoterminal1 Task 3
ExamplePseudoterminal2 Task 1, ExamplePseudoterminal2 Task 2, ExamplePseudoterminal2 Task 3

ExamplePseudoterminal1 Task <number> 任务接受一个参数 <number> 并在终端上打印出 <number>。 ExamplePseudoterminal2 Task <number> 任务接收参数 <number> 并向终端打印 2 *<number>。

问题

当我运行一个任务（Terminal -> Run Task... -> "MyTask"）时，上面列出的所有任务都显示出来了。但是，every 其中一项任务的结果是最后添加的任务（即 ExamplePseudoterminal2 Task 3 -> 6).

我做错了什么？

我忘记了什么吗？

基于 github: microsoft/vscode-extension-samples 示例的解决方案。这使用了 vscode.TaskProvider 的更完整定义。重要的部分似乎是：interface CustomBuildTaskDefinition extends vscode.TaskDefinition 和 package.json 中的完整 taskDefinitions。

src/extension.ts

import * as vscode from 'vscode';

export function activate(context: vscode.ExtensionContext) {

    console.log('Congratulations, your extension "exampleext" is now active!');

    const myTask_TaskProvider: vscode.Disposable = vscode.tasks.registerTaskProvider(
        CustomBuildTaskProvider.TaskType, new CustomBuildTaskProvider()
    );

    context.subscriptions.push(myTask_TaskProvider)
}

export function deactivate() {
}


interface CustomBuildTaskDefinition extends vscode.TaskDefinition {
    number: number;
}

export class CustomBuildTaskProvider implements vscode.TaskProvider {
    static TaskType = 'custombuildscript';
    private tasks: vscode.Task[] | undefined;

    constructor() { }

    public async provideTasks(): Promise<vscode.Task[]> {
        return this.getTasks();
    }

    public resolveTask(_task: vscode.Task): vscode.Task | undefined {
        const type: string = _task.definition.type;
        if (type === CustomBuildTaskProvider.TaskType) {
            const definition: CustomBuildTaskDefinition = <any>_task.definition;
            return this.getTask(definition);
        }
        return undefined;
    }

    private getTasks(): vscode.Task[] {
        if (this.tasks !== undefined) {
            return this.tasks;
        }

        const in_values: number[] = [1, 2, 3];

        this.tasks = [];
        in_values.forEach(value => {
            const active_def: CustomBuildTaskDefinition = {
                type: CustomBuildTaskProvider.TaskType,
                number: value
            }
            this.tasks!.push(this.getTask(active_def));
        });
        return this.tasks;
    }

    private getTask(definition: CustomBuildTaskDefinition): vscode.Task {

        return new vscode.Task(
            definition,
            vscode.TaskScope.Workspace,
            `TestTask ${definition.number}`,
            definition.type, new vscode.CustomExecution(
                async (): Promise<vscode.Pseudoterminal> => {
                    return new ExamplePseudoterminal1(definition.number);
                }
            ),
            [""]
        );
    }
}


class ExamplePseudoterminal1 implements vscode.Pseudoterminal {

    private readonly writeEmitter = new vscode.EventEmitter<string>();
    public onDidWrite: vscode.Event<string> = this.writeEmitter.event;

    private readonly closeEmitter = new vscode.EventEmitter<void>();
    public onDidClose?: vscode.Event<void> = this.closeEmitter.event;

    private value: number;

    public constructor(in_number: number) {
        this.value = in_number;
        console.log(`this.value: ${this.value}`);
    }

    public open(initialDimensions: vscode.TerminalDimensions | undefined) {
        console.log("open");

        this.writeEmitter.fire(`${this.value}`);

        this.closeEmitter.fire();
    }

    close(): void {
        console.log("close");
    }
}
