Cordova插件在構建時出錯，在源1.6中不支持Diamond運算符，請使用源7

問題描述

我正在開發具有離子框架的應用程序，並且在該應用程序中，我正在創建用於使用本機android java的cordova插件。

問題是，在構建時，我得到了一個與關於源的cordova插件有關的錯誤。 我已經安裝了Java 1.8 JDK和JRE。

這是建築的輸出

IntelliJ IDEA配置為使用API​​ 22和Javas 1.8

我認為問題出在cordova插件中，也許我必須在plugin.xml中添加類似於android sdk API的內容

例如： 

<preference name="android-minSdkVersion" value="19"/>

cordova插件的部分代碼是一個舊的android studio項目的一部分，該項目可以完美工作並且編譯時不會出現此錯誤。

謝謝

更新：

我發現了這一點：在使用gradle 構建Cordova項目時覆蓋Java版本：在使用gradle構建Cordova項目時覆蓋Java版本

我已將版本1_8更改為： 

android {
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

現在我有一個非常嚴重的錯誤，將太多行放在這里，但是開始是：

我使用菱形運算符解決了該錯誤，使用方式如下： 

    List<byte[]> listgen = new ArrayList<byte[]>();

也許這將與您的Cordova插件一起使用。
