我将SCDF与跳过服务器2.3.2和数据流服务器2.4.2结合使用。与Docker-compose一起部署 我使用composite-task-runner 2.1.3版本构建了任务 我尝试执行任务，但是即使使用示例，composite-task-runner也不启动任务
示例：

你能帮我吗？我在使用Postgres DB
新评论：
我按照文档中的说明构建了一个新的合成任务：
testComposedTaskA，定义为myTask &&时间戳
数据流：>任务列表
╔═══════════════════════════╤═══════════════════╤═══════════╤═══════════╗
║ Task Name │ Task Definition │description│Task Status║

子任务从不执行。在示例中，我们可以看到子任务已执行 怎么了？

在日志composed-task-runner && mytask && myTask中，用于创建“合成任务”定义的语法看起来不正确。
应用名称composed-task-runner不应成为任务DSL的一部分。
您可以查看here，以获取有关如何创建和管理组合任务的详细文档。
