Question

我想从Google（Kotlin语言）通过Udacity course构建演示项目。在Github上进行项目下载。

开始Android Studio并选择Import project
打开代码后，我看到弹出窗口要求更新gradle插件，选择了Don't remind me again for this project。根据Udacity课程的指导。
现在，我看到了built: completed successfully。

但是当我在物理或虚拟设备上单击Run时，出现异常。

e: java.util.ServiceConfigurationError: 
   javax.annotation.processing.Processor: 
   android.databinding.annotationprocessor.ProcessDataBinding
   Unable to get public no-arg constructor

我尝试了clean project（也尝试过rebuild），然后又尝试了Run。同样的例外。

我找到了topic，并将下一个添加到build.gradle

// JAX-B dependencies for JDK 9+
implementation "javax.xml.bind:jaxb-api:2.2.11"
implementation "com.sun.xml.bind:jaxb-core:2.2.11"
implementation "com.sun.xml.bind:jaxb-impl:2.2.11"
implementation "javax.activation:activation:1.1.1"

在这种情况下，我例外了

Task :app:kaptGenerateStubsDebugKotlin
e: path\andfun-kotlin-android-trivia-starter-code\app\build\generated\data_binding_base_class_source_out\debug\dataBindingGenBaseClassesDebug\out\com\example\android\navigation\databinding\ActivityMainBinding.java:13: error: cannot find symbol
  protected ActivityMainBinding(DataBindingComponent _bindingComponent, View _root,
  symbol:   class DataBindingComponent
  location: class ActivityMainBinding
  ...
  e: java.lang.IllegalStateException:  failed to analyze: 
  java.lang.reflect.InvocationTargetException

我是初学者。你能告诉我，我该怎么办？我只是想参加一门课程，而我却浪费时间在晦涩的异常上。

Android Studio 3.4.2
下载了适用于19、27、28 API的SDK
物理设备27 API
虚拟设备28 API
JDK 9.0.4

Answer 1

问题在于JDK。我有外部JDK 9.0.4，它可以与Java的Android应用一起使用，但不适用于Kotlin。解决方案很简单，但对我来说却很难解决。

将项目打开到Android Studio中，然后转到：

File -> Project Structure -> SDK Location

设置支票Use embedded JDK
尝试构建您的项目，为我工作

Answer 2

由于JDK版本不匹配，出现了问题。例如，您的系统具有JDK 11或12，而android studio具有JDK 8，并且您已设置JRE嵌入式路径（Android studio文件夹）。

要解决此错误，您需要在所有位置使用相同的JDK。注意：请使用与Android studio中相同的JDK版本设置JAVA_HOME和JDK路径。

演示应用程序构建失败。如何解决例外情况？
