java - 如何在 gradle 3 或更高版本中使用 jar 文件？

Question

在我的项目中，“app”模块还使用放置在其依赖模块之一中的 jar 库。当我使用 Gradle 2 和 Gradle Plugin 2.3 时效果很好。然后我将 Gradle 版本更新为 5.1.1 并将 Android Gradle 插件版本更新为 3.4.2 并遇到以下问题。

如果我将 jar 放在两个模块的 libs 文件夹中，则会出现第一个屏幕截图中的错误。但是，如果我删除“app”模块中的 jar，它只是无法识别 jar 中的类，如第二个屏幕截图所示。当我使用旧的 Gradle 时，它​​能够使用这些类。

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    testImplementation 'junit:junit:4.13-beta-3'
    implementation 'me.zhanghai.android.materialratingbar:library:1.3.2'

    implementation 'com.flurry.android:analytics:11.6.0@aar'

    implementation project(':dayWeekLib')
    implementation (project(':zappasoft-android-support-library'))
//    {
//        exclude module: 'libs/YouTubeAndroidPlayerApi'
//        exclude group: 'com.google.android.youtube.player'
//    }

    implementation ('androidx.appcompat:appcompat:1.0.2')

    implementation ('com.google.android.material:material:1.0.0')

    implementation ('androidx.recyclerview:recyclerview:1.0.0')

    implementation ('androidx.legacy:legacy-support-v13:1.0.0')

    implementation 'com.google.firebase:firebase-messaging:19.0.1'
}

I think you implementation is wrong. First you have to put your jar file in your libs folder. then in your gradle add implementation
files('libs/your_jar.jar')
