kotlin配置ARouter问题，解决org.jetbrain

问题1：

w: 警告: 来自注释处理程序 'org.jetbrains.kotlin.kapt3.base.ProcessorWrapper' 的受支持 source 版本 'RELEASE_7' 低于 -source '1.8'

问题2：

[kapt] An exception occurred: java.lang.RuntimeException: ARouter::Compiler >>> No module name, for more information, look at gradle log.

对于纯java代码的gradle的ARoute的配置应该是这样的

defaultConfig {
        minSdkVersion rootProject.ext.minSdkVersion
        targetSdkVersion rootProject.ext.targetSdkVersion

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
        javaCompileOptions { annotationProcessorOptions { includeCompileClasspath = true } }
        javaCompileOptions {
            annotationProcessorOptions {
                arguments = [AROUTER_MODULE_NAME: project.getName()]
            }
        }
    }

dependencies {
       annotationProcessor 'com.alibaba:arouter-compiler:1.2.2'
}

AnnotationProcessor是编译时注解处理器
这样就ok了

对于java和kt的混编如果这样配置就会遇到上面的问题
我这面这样配置的

  apply plugin: 'kotlin-kapt'

  defaultConfig {
        minSdkVersion rootProject.ext.minSdkVersion
        targetSdkVersion rootProject.ext.targetSdkVersion
        dataBinding.enabled = true
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
        javaCompileOptions { annotationProcessorOptions { includeCompileClasspath = true } }
        javaCompileOptions {
           annotationProcessorOptions {
                arguments = [ AROUTER_MODULE_NAME: project.getName() ]
           }
       }

    }

kapt {
    arguments {
        arg("moduleName", project.getName())
        includeCompileClasspath = true
    }
    generateStubs = true
}


  dependencies {
       kapt 'com.alibaba:arouter-annotation:1.0.6'
       kapt 'com.alibaba:arouter-compiler:1.2.2'
}

这样就搞定了，处理了警告及ARoute的编译时代码不生成的问题。
就可以正常编译了。
