Question

将Android Studio升级到4.0版本后，Lombok注释停止工作。升级之前，相同的代码正在编译，没有错误。

代码：

    import lombok.AllArgsConstructor;
    import lombok.Builder;
    import lombok.Getter;
    import lombok.experimental.Accessors;

    @Getter
    @Builder
    @Accessors(fluent = true)
    @AllArgsConstructor
    public class UrlData {

        private int id;
        private String url;

    }

在尝试编译时，我收到以下警告，最后得到一个错误（不确定所有警告是否都相关）：

> Task :mycorelib:kaptDebugKotlin
[WARN] Incremental annotation processing requested, but support is disabled because the following processors are not incremental: org.greenrobot.eventbus.annotationprocessor.EventBusAnnotationProcessor (NON_INCREMENTAL).

> Task :app:kaptMyPrjDebugKotlin

  Your processor is: org.jetbrains.kotlin.kapt3.base.incremental.IncrementalProcessingEnvironment
  Lombok supports: OpenJDK javac, ECJ

error: cannot find symbol
        startActivity(WebViewActivity.getIntent(getActivity(), urlData.url()));
                                                                       ^
  symbol:   method url()
  location: variable urlData of type UrlData

是否可以解决此问题，还是应该删除不受支持的lombok？

诀窍似乎是忽略Studio / IntelliJ的建议，将compileOnly-lombok行替换为annotationProcessor，并在build.gradle中保留两行：

compileOnly 'org.projectlombok:lombok:1.18.16'
annotationProcessor 'org.projectlombok:lombok:1.18.16'

升级到Android Studio 4.0后，Lombok注释不起作用
