这是我第一次做gradle，不是从头开始的，我在这里用这个代码作为我的源代码，它是用gradle构建的；https://github.com/kaaz/discordbot
几天前，当我尝试用intellij构建gradle时，它运行得非常好。然后，我将它保留了几天，没有对代码或intellij设置本身进行任何更新或编辑。但是，今天我第一次打开它，突然这个通知导致构建失败 java.lang.NoClassDefFoundError: org/gradle/api/internal/plugins/DefaultConvention 它让我把androidsdk放到我的intellij上。我试着在网上查，结果大多发生在他们做android项目的时候。同时，我正在做的是一个不和谐的机器人项目-所以，我不确定把android sdk放到我的intellij中是否是最好的方法。
这就是我所拥有的
