构建代码时出现此错误：

Error:Execution failed for task ':app:javaPreCompileDebug'.
> 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-1.16.14.jar (org.projectlombok:lombok:1.16.14)
  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.

这是我的项目gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'



        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }

Answer 1

It tells you what to do...

> 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-1.16.14.jar (org.projectlombok:lombok:1.16.14)

Like so

    dependencies {

        // Other dependencies
        compileOnly "org.projectlombok:lombok:1.18.4"
        annotationProcessor 'org.projectlombok:lombok:1.18.4'
    }

[See Lombok documentation](https://projectlombok.org/setup/android)

Also, I suggest you delete `libs/json-20140107.jar` and replace it with 

    compile 'org.json:json:20140107'

Although, Android already has a JSON parser, so not clear why you need this at all

Answer 2

只需将以下行添加到您的Module：app gradle文件中

dependencies {
    compileOnly "org.projectlombok:lombok:1.18.4"
    annotationProcessor 'org.projectlombok:lombok:1.18.4'
 }

错误：任务“：app：javaPreCompileDebug”的执行失败
