> Annotation processors must be explicitly declared now.  The following dependencies on the compile classpath are found to contain annotation processor.  Please add them to the annotationProcessor configuration.
    - lombok-1.16.8.jar (org.projectlombok:lombok:1.16.8)
  Alternatively, set android.defaultConfig.javaCompileOptions.annotationProcessorOptions.includeCompileClasspath = true to continue with previous behavior.  Note that this option is deprecated and will be removed in the future.

  See https://developer.android.com/r/tools/annotation-processor-error-message.html for more details.

解决办法： 在app  build.gradle 

defaultConfig {
        applicationId "com.example.wbxu.myapplication"
        minSdkVersion 15
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        //添加部分
        javaCompileOptions {
            annotationProcessorOptions {
                includeCompileClasspath true
            }
        }
    }
