我在viewModel里去添加*号的时候会报错，是英文的*,一运行报错如图，我去google 和百度了一圈说是build.gradle 设置kotlin版本的问题，我看了一下kotlin版本应该是没有问题的，请问怎么解决这个问题

public inline operator fun BigDecimal.times(other: BigDecimal): BigDecimal defined in kotlin

public inline operator fun BigInteger.times(other: BigInteger): BigInteger defined in kotlin
