找不到参数的方法 api() [目录 'libs'] [英] Could not find method api() for arguments [directory 'libs']

问题描述

打开文件

这是我的 gradle 文件:

This is my gradle file:

apply plugin: 'com.android.application'

    android {
        compileSdkVersion 27
        buildToolsVersion "27.0.1"
        defaultConfig {
            applicationId "com.landdrops.cricketfantacy.androidbottom"
            minSdkVersion 21
            targetSdkVersion 27
            versionCode 1
            versionName "1.0"
            testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        }
        buildTypes {
            release {
                minifyEnabled false
                proguardFiles getDefaultProguardFile('proguard android.txt'), 'proguard-rules.pro'
            }
        }
    }

    dependencies {
        implementation fileTree(include: ['*.jar'], dir: 'libs')
        implementation 'com.android.support:appcompat-v7:27.0.1'
        implementation 'com.android.support:design:27.0.1'
        implementation 'com.android.support.constraint:constraint-layout:1.0.2'
        testImplementation 'junit:junit:4.12'
        androidTestImplementation 'com.android.support.test.runner:1.0.2'
        androidTestImplementation 'com.android.support.test.espresso:espresso-core:2.2.2'
    }

我得到了

错误:(23, 0) 无法在 org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler 类型的对象上找到参数 [directory 'libs'] 的方法 implementation().打开文件

Error:(23, 0) Could not find method implementation() for arguments [directory 'libs'] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler. Open File

推荐答案

我能够通过将大多数依赖项更新到当前版本来纠正此错误(不确定是否有必要，并且当最新版本与另一个组件的依赖项发生冲突时, 我恢复了一个版本，它清除了不匹配.此时，我使用 27.1.0 进行 appCompat 设计.(我使用 27.0.3 作为构建工具)

I was able to correct this error by updating most dependencies to current version (not sure that necessary, and when the most current version conflicted with a dependency of another component, I reverted one release back and it cleared up the mismatch. At this time, I am using 27.1.0 for appCompat, design. (I use 27.0.3 for build tools tho)

Gradle wrapper 到 4.4 版(这实际上是我在加载过时项目和更新插件时提示我做的)

Gradle wrapper to version 4.4 (this was actually prompted for me to do when loading an outdated project and updating the plugin)

调整项目 build.gradle 使用:类路径 'com.android.tools.build:gradle:3.1.1'

Adjusted project build.gradle to use: classpath 'com.android.tools.build:gradle:3.1.1'
