【问题描述】：

这是我的 ChatInformation kotlin 类：

open class ChatInformation(
    var Id: Int = 0,
    var TopicId: Int = 0,
    var CreateTime: String? = null,
    var StartTime: String? = null,
    var EndTime: String? = null,
    var StatusId: Int = 0,
    var Duration: String? = null,
    var TeacherId: String = "",
    var LearnerId: String = "",
    var SubjectName: String = "",
    var TopicTitle: String = "",
    var Class: Int = 0,
    var Learner: String = "",
    var Teacher: String = "",
    var TeacherReady: Boolean = false,
    var LearnerReady: Boolean = false
) : RealmObject()

如果我添加这个类，我会得到以下错误：

Error:Execution failed for task ':app:compileDebugJavaWithJavac'.Compilation failed; see the compiler error output for details.

如果看到编译器这个

错误跟踪很长

如果我删除或评论 ChatInformation 类构建成功，错误在哪里？我在 3.5.0 和 3.7.1 版本中都尝试过

【解决方案1】：

我的错误是：我有一个

var 类：Int = 0

我的 ChatInformation 类中的字段，如果删除此字段效果很好
