在Kotlin中配置dataBinding项目无法运行

E/LoadedApk: Unable to instantiate appComponentFactory    java.lang.ClassNotFoundException: Didn't find class "androidx.core.app.CoreComponentFactory" on path: DexPathList[[zip file "/data/app/com.gfk.newbie-ST1BhCAkKBtme6Itbi3SEQ==/base.apk"],nativeLibraryDirectories=[/data/app/com.gfk.newbie-ST1BhCAkKBtme6Itbi3SEQ==/lib/arm, /data/app/com.gfk.newbie-ST1BhCAkKBtme6Itbi3SEQ==/base.apk!/lib/armeabi-v7a, /system/lib]]        at dalvik.system.BaseDexClassLoader.findClass(BaseDexClassLoader.java:134)        at java.lang.ClassLoader.loadClass(ClassLoader.java:379)        at java.lang.ClassLoader.loadClass(ClassLoader.java:312)        at android.app.LoadedApk.createAppFactory(LoadedApk.java:226)        at android.app.LoadedApk.createOrUpdateClassLoaderLocked(LoadedApk.java:739)        at android.app.LoadedApk.getClassLoader(LoadedApk.java:818)        at android.app.LoadedApk.getResources(LoadedApk.java:1041)        at android.app.ContextImpl.createAppContext(ContextImpl.java:2394)        at android.app.ActivityThread.handleBindApplication(ActivityThread.java:5948)        at android.app.ActivityThread.access$1300(ActivityThread.java:207)        at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1758)        at android.os.Handler.dispatchMessage(Handler.java:106)        at android.os.Looper.loop(Looper.java:193)        at android.app.ActivityThread.main(ActivityThread.java:6898)        at java.lang.reflect.Method.invoke(Native Method)        at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:537)        at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:858)

最近在项目中要用到dataBinding来进行数据绑定，但只要一配置

 dataBinding {        enabled = true    }

就会报这样的错，java.lang.ClassNotFoundException: Didn't find class "androidx.core.app.CoreComponentFactory" on path: DexPathList，试了很多办法都不行，最后发现在Java工程环境下不报错，在Kotlin工程环境下就会有问题，于是加上下面这几行代码就解决了

 //在android闭包里面添加支持 java-8    compileOptions {        sourceCompatibility JavaVersion.VERSION_1_8        targetCompatibility JavaVersion.VERSION_1_8    }    dataBinding {        enabled = true    }
