java - 使用 Kotlin Kapt 失败 : error: scoping construct cannot be annotated with type-use annotation: @org. jetbrains.annotations.NotNull

Question

我将 Vertx Service Gen 注释处理器与 Kotlin kapt 结合使用。

在注释处理器启动之前，我的 kapt 失败，到处都是以下异常消息:

error: scoping construct cannot be annotated with type-use annotation: @org.jetbrains.annotations.NotNull

示例如下:

e: C:\Users\...\build\tmp\kapt3\stubs\main\com\_masked_\objects\User.java:10: error: scoping construct cannot be annotated with type-use annotation: @org.jetbrains.annotations.NotNull
    public abstract java.lang.String getUserName();

e: C:\Users\...\build\tmp\kapt3\stubs\main\com\_masked_\objects\User.java:13: error: scoping construct cannot be annotated with type-use annotation: @org.jetbrains.annotations.NotNull
    public abstract java.lang.String getUrlKey();
                             ^
e: C:\Users\...\build\tmp\kapt3\stubs\main\com\_masked_\objects\User.java:16: error: scoping construct cannot be annotated with type-use annotation: @org.jetbrains.annotations.NotNull
    public abstract com._.objects.File getAvatar();
                                       ^
...

kapt生成的源代码:

public abstract interface User {
    public static final com._.objects.User.Companion Companion = null;

    @org.jetbrains.annotations.NotNull()
    public abstract java.lang.String getUserName(); // line 10

    @org.jetbrains.annotations.NotNull()
    public abstract java.lang.String getUrlKey(); // line 13

    @org.jetbrains.annotations.NotNull()
    public abstract com._.objects.File getAvatar(); // line 16
...
}

它的 kotlin 源文件如下所示:

interface User {

    val userName: String
    val urlKey: String
    val avatar: File
    val signature: String

}

通过阅读this thread ，我现在有点了解情况了，但是我该如何解决这个问题呢？

Answer 1

这是一个 kapt bug，问题跟踪器 link

kotlin 团队提供的解决方法是添加 实现(“org.jetbrains:annotations:15.0”) 到 gradle bulid 文件。
