NPE  NdkHandler找不到？

org.gradle.api.ProjectConfigurationException: A problem occurred configuring project ':native'

Caused by: java.lang.NullPointerException
at com.android.build.gradle.internal.ndk.NdkHandler.getPlatformVersion(NdkHandler.java:121)


AS是最新的Arctic Fox，gradle都是源码里的版本，后面改成最新的7.0.3还是这个问题。
