“libModule”中的实现项目“:app”不起作用

Question

我需要在 Android Studio 中创建模块，其中包含对主项目的依赖。我创建新的项目和模块，将实现添加到库 gradle，如下所示：

implementation project(':app')

但是当我尝试同步 gradle 时，我遇到了下一个错误：

Unable to resolve dependency for ':mylibrary@debug/compileClasspath': Could not resolve project :app.

Unable to resolve dependency for ':mylibrary@debugAndroidTest/compileClasspath': Could not resolve project :app.

Unable to resolve dependency for ':mylibrary@debugUnitTest/compileClasspath': Could not resolve project :app.

Unable to resolve dependency for ':mylibrary@release/compileClasspath': Could not resolve project :app.

Unable to resolve dependency for ':mylibrary@releaseUnitTest/compileClasspath': Could not resolve project :app.

有什么想法为什么会发生以及如何解决它吗？

更新

这是应用程序 gradle（非常空）

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

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.pro100svitlo.testproject"
        minSdkVersion 21
        targetSdkVersion 28
        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(dir: 'libs', include: ['*.jar'])
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    implementation 'com.android.support:design:28.0.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

这是库 gradle：

apply plugin: 'com.android.library'

android {
    compileSdkVersion 28

    defaultConfig {
        minSdkVersion 21
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"

    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation project(':app')
}

试试这个，在类似的情况下对我有用。注意项目在()中没有空格

enter code here

实现（项目（“：app”））
