我有一个 AS3 / gradle plugin 3 项目，我们最近在其中引入了一个本地简单的注释处理器。与 gradles annotationProcessor 依赖指令一起工作正常。
我开始添加 Kotlin 代码并将所有 annotationProcessor 指令移至 kapt 指令。Glide 和 logan-square 使用 Kotlin 的注解处理器没有问题，但是我们本地的 AP 项目不能被 kapt 执行：

但是，创建的 JAR 文件具有必要的 META-INF JAR 条目：

主模块 build.gradle 的摘录：
dependencies {
// gazillions of compile / api / ...
api project(':ejecta-v8:v8annotations')
kapt project(':ejecta-v8:v8annotations-compiler')
}
模块 v8annotations build.gradle：
apply plugin: 'java-library'
sourceCompatibility = 1.8
targetCompatibility = 1.8
dependencies {}
模块 v8annotations-compiler build.gradle：
apply plugin: 'java'
sourceCompatibility = 1.8
targetCompatibility = 1.8
dependencies {

compile fileTree(dir: 'libs', include: ['*.jar'])
}
我很难过:(
