解决A failure occurred while executing org.jetbrains.kotlin.gradle.internal.KaptWithoutKotlincTask

构建Kotlin项目时报错如下：

Execution failed for task ':app:kaptDebugKotlin'.
> A failure occurred while executing org.jetbrains.kotlin.gradle.internal.KaptWithoutKotlincTask$KaptExecutionWorkAction
   > java.lang.reflect.InvocationTargetException (no error message)

先检查是否有其他报错信息：

例如：

错误: cannot generate view binders java.lang.NullPointerException  	at android.databinding.tool.store.SetterStore.calculateConversionPriority(SetterStore.java:995)  	at android.databinding.tool.store.SetterStore.isBetterParameter(SetterStore.java:890)  	at android.databinding.tool.store.SetterStore.getBestSetter(SetterStore.java:750)  	at android.databinding.tool.store.SetterStore.getSetterCall(SetterStore.java:572)  	at android.databinding.tool.Binding.getListenerParameter(Binding.java:175)  	at android.databinding.tool.Binding.resolveCallbackParams(Binding.java:77)  	at android.databinding.tool.BindingTarget.resolveCallbackParams(BindingTarget.java:179)  	at android.databinding.tool.LayoutBinder.(LayoutBinder.java:142)  	at android.databinding.tool.DataBinder.(DataBinder.java:61)  	at android.databinding.tool.CompilerChef.ensureDataBinder(CompilerChef.java:118)  	at android.databinding.tool.CompilerChef.sealModels(CompilerChef.java:370)

这是说ViewDataBinding有问题，检查XML文件是否有引用错误的地方。

2.排除掉代码层面和xml层面的问题之后，考虑这种问题多半是版本不匹配造成的。一般按照以下步骤排查即可解决：
