Unable to find method 'org.gradle.api.tasks.TaskInputs.file

在配置greenDao项目的时候，经常会遇到这样的问题，全部的提示如下

Unable to find method ‘org.gradle.api.tasks.TaskInputs.file(Ljava/lang/Object;)Lorg/gradle/api/tasks/TaskInputs;’.
Possible causes for this unexpected error include:
Gradle’s dependency cache may be corrupt (this sometimes occurs after a network connection timeout.)
Re-download dependencies and sync project (requires network)

The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem.
Stop Gradle build processes (requires restart)

Your project may be using a third-party plugin which is not compatible with the other plugins in the project or the version of Gradle requested by the project.

In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes.

 导致这个问题的原因是gradle版本的问题，在我这里出现这个问题时的配置如下

android studio 4.0.0
gradle:6.1.1
gradle Plugin:3.2.0
greenDao: 3.2.0

修改之后可以正常使用的配置如下

android studio 4.0.0
gradle:6.1.1
gradle Plugin:3.3.0
greenDao: 3.2.0

正确配置，外面的build.gradle的buildscript中配置gradle

buildscript {
    repositories {
        google()
        jcenter()
        maven { url 'https://oss.sonatype.org/content/repositories/snapshots' }
    }
    dependencies {
        classpath "com.android.tools.build:gradle:4.0.0-rc01"
        // 使用butterknife需要实现以下方法
        classpath 'com.github.dcendents:android-maven-gradle-plugin:2.1'
        classpath 'org.greenrobot:greendao-gradle-plugin:3.3.0'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

 在里面的build.gradle中配置

apply plugin: 'com.android.application'
apply plugin: 'org.greenrobot.greendao' // 添加应用依赖插件

android {
    compileSdkVersion 29

    defaultConfig {
        applicationId "com.example.easygreendao"
        minSdkVersion 16
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }

// 配置GreenDao基本参数
    greendao {
        schemaVersion 1 //当前数据库版本
    }

}

dependencies {
    implementation fileTree(dir: "libs", include: ["*.jar"])
    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test.ext:junit:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'


    //greendao
    implementation 'org.greenrobot:greendao:3.2.0' // add library
    implementation 'org.greenrobot:greendao-generator:3.2.0' // add library
    implementation 'com.github.yuweiguocn:GreenDaoUpgradeHelper:v2.1.0'

}

 经过上面配置，可以正常编译运行。
