不能在Android项目中使用本地注释处理器

Question

我有一个AS3 / gradle插件3项目，我们最近引入了一个本地简单的注释处理器。可以很好地使用梯度annotationProcessor依赖指令。

我开始添加Kotlin代码，并将所有annotationProcessor指令移到kapt指令中。Glide和logan-square使用Kotlin的注释处理器，没有任何问题，但是我们的本地AP项目不能由kapt执行：

但是，创建的JAR文件有必要的META条目：

摘录自主模块build.gradle：

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v8注释-编译器build.gradle：

apply plugin: 'java'

sourceCompatibility = 1.8
targetCompatibility = 1.8

dependencies {
    compile project(':ejecta-v8:v8annotations')
    compile fileTree(dir: 'libs', include: ['*.jar'])
}

我很困惑：

Answer 1

我也有过几次类似的问题。我尝试了一个组合

pkill gradle
pkill java

并删除. .idea/workspace.xml的android设置和*.iml文件。这似乎是一个缓存状态，导致了这个问题。

Answer 2

在我的例子中，它已经足够运行了

gradlew --stop

来自AndroidStudio控制台

Answer 3

对我来说很管用

pkill gradle 
clean project 
make project
