java - 错误: cannot find symbol DaoSession and DaoMaster

Question

我在我的应用程序中使用 GreenDao。 Proguard 已启用用于调试构建。

添加数据绑定(bind)支持后，出现以下问题:

/app/src/main/java/com/example/MainApplication.java:29: error: cannot find symbol

private DaoSession mDaoSession;

      ^   

symbol: class DaoSession
location: class Main Application

DaoMaster 也出现同样的问题。

另外，这个问题即将到来:

org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:kaptDebugKotlin'.
    at org.gradle.api.internal.tasks.execution.ExecuteActionsTaskExecuter.executeActions(ExecuteActionsTaskExecuter.java:103)
    at org.gradle.api.internal.tasks.execution.ExecuteActionsTaskExecuter.execute(ExecuteActionsTaskExecuter.java:73)

应用程序构建.gradle:

apply plugin: 'kotlin-kapt'
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
//For green dao
apply plugin: 'org.greenrobot.greendao'

buildscript {
    ext.kotlin_version = '1.2.41'
    ...
}
android {
    aaptOptions.cruncherEnabled = false
    aaptOptions.useNewCruncher = false
    ...
    }
    dataBinding {
        enabled = true
    }

    buildTypes {
        debug {
            minifyEnabled true
            shrinkResources true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    kapt { generateStubs = true }
}

dependencies {
    implementation 'com.android.support:appcompat-v7:27.1.1'
    implementation 'org.greenrobot:greendao:3.2.2'
    implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
    implementation 'org.jetbrains.anko:anko-common:0.8.3'
    kapt 'com.android.databinding:compiler:3.1.2'
}

apply plugin: 'kotlin-android-extensions'

项目build.gradle:

buildscript {
    ext.kotlin_version = '1.2.41'
    dependencies {
        classpath  'com.android.tools.build:gradle:3.1.2'
        classpath 'org.greenrobot:greendao-gradle-plugin:3.2.2'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}
...

Answer 1

像这样更改你的应用程序 build.gradle:

//For green dao
apply plugin: 'org.greenrobot.greendao'

apply plugin: 'kotlin-kapt'
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'

将 greendao 插件移到 kotlin 插件之前。
