我希望我的recast.bot回复用户的回复。这是代码，但是下面出现了错误消息。如何解决这个问题？

Bot Server is running on port 5002

我正在关注他们的SDK：https：//github.com/RecastAI/SDK-NodeJS/wiki/Receive-and-send-messages

    const express = require('express');
    const bodyParser = require('body-parser');
    const recastai = require('recastai').default;
    const build = new recastai.build('xxxxxx', 'en');

    var client = new recastai('xxxxxx')

    const app = express();
    const …

我在构建 Cordova Android 应用程序时收到此错误消息。

错误：(159, 66) 错误：-source 1.7 不支持 lambda 表达式（使用 -source 8 或更高版本启用 lambda 表达式）

以下compileOptions已在我的build.gradle（模块android）和build.gradle（模块CordovaLib）上设置，如下所示：

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

如何解决这个问题？
