Room Kotlin Cannot find setter for field

Hi I'm trying to use Room with Kotlin in a MVP based Project.

my problem is that when I create a data class and related DAO all the classes would generated successfully but when a create the second data class and it's DAO the Error:Cannot find setter for field. thrown on rebuild command in android studio 

@Entity(tableName = "TB_CLASSES")
class TbClass(
@ColumnInfo(name = "ID")
@PrimaryKey(autoGenerate = true)  var id: Int =-1,
@ColumnInfo(name = "NAME") var name: String="",
@ColumnInfo(name = "CAPTION") var caption: String="",
@ColumnInfo(name = "TYPE") var type: String="")

@Entity(tableName = "TB_FEATURE_DISA")
class TbFeatureDisa(
@ColumnInfo(name = "ID")
@PrimaryKey(autoGenerate = true) var id: Int=-1,
@ColumnInfo(name = "FEATURE_ID") var featureId: Int=-1,
@ColumnInfo(name = "DISA_ID") var disaId: Int=-1,
@ColumnInfo(name = "IS_SOLVED") var isSolved: Int=-1,
@ColumnInfo(name = "DISA_LEVEL") var disaLevel: Double=-0.1,
@ColumnInfo(name = "RESOLVER_USER_NAME") var resolverUserName: String="",
@ColumnInfo(name = "RESOLVE_TIME") var resolveTime: Date? =null,
@ColumnInfo(name = "REPORT_VIST_ID") var reportVisitId: Int=-1,
@ColumnInfo(name = "REPORT_FAULT_ID") var reportFaultId: Int=-1,
@ColumnInfo(name = "SOLVE_VIST_ID") var solveVisitId: Int=-1,
@ColumnInfo(name = "SOLVE_SERVICE_ID") var solveServiceId: Int=-1,
@ColumnInfo(name = "SOLVE_FUALT_ID") var solveFaultId: Int=-1)

I've also checked this link and this link but none of them worked for me

For the folks who lack attention like me and stumbled here via Google, using val instead of var gives the same error message.

I finally found the solution. The problem is related to property naming.

The following causes errors at compile time:

 @ColumnInfo(name = "IS_SOLVED") var isSolved

but when I changed the above to the following, the error is resolved:

 @ColumnInfo(name = "IS_SOLVED") var solved

We cannot use SQLite reserved keywords line for field naming. I'm using Room version 1.0.0 and kotlin version 1.1.51.

Create a data class which will provide setters and getters for properties as in 

@Entity(tableName = "TB_CLASSES")
data class TbClass( //< add data prior to class
@ColumnInfo(name = "ID")
@PrimaryKey(autoGenerate = true)  var id: Int =-1,
@ColumnInfo(name = "NAME") var name: String="",
@ColumnInfo(name = "CAPTION") var caption: String="",
@ColumnInfo(name = "TYPE") var type: String="")

TbFeatureDisa

    @Entity(tableName = "TB_FEATURE_DISA")
    data class TbFeatureDisa(
    @ColumnInfo(name = "ID")
    @PrimaryKey(autoGenerate = true) var id: Int=-1,
    @ColumnInfo(name = "FEATURE_ID") var featureId: Int=-1,
    @ColumnInfo(name = "DISA_ID") var disaId: Int=-1,
    @ColumnInfo(name = "IS_SOLVED") var isSolved: Int=-1,
    @ColumnInfo(name = "DISA_LEVEL") var disaLevel: Double=-0.1,
    @ColumnInfo(name = "RESOLVER_USER_NAME") var resolverUserName: String="",
    @ColumnInfo(name = "RESOLVE_TIME") var resolveTime: Date? =null,
    @ColumnInfo(name = "REPORT_VIST_ID") var reportVisitId: Int=-1,
    @ColumnInfo(name = "REPORT_FAULT_ID") var reportFaultId: Int=-1,
    @ColumnInfo(name = "SOLVE_VIST_ID") var solveVisitId: Int=-1,
    @ColumnInfo(name = "SOLVE_SERVICE_ID") var solveServiceId: Int=-1,
    @ColumnInfo(name = "SOLVE_FUALT_ID") var solveFaultId: Int=-1)
