无法解析'：app @ debug / compileClasspath'的依赖项：无法解析com.daimajia.slider：library：1.1.5

Question

我尝试使用AndroidImageSlider库，但出现此错误：

Unable to resolve dependency for ':app@debug/compileClasspath': Could 
not resolve com.daimajia.slider:library:1.1.5.

在我的build.gradle中有这种依赖项

implementation 'com.nineoldandroids:library:2.4.0'
implementation 'com.daimajia.slider:library:1.1.5@aar        
implementation 'com.squareup.picasso:picasso:2.5.2'
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support:design:27.1.1'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
testImplementation 'junit:junit:4.12'

Answer 1

1. 尝试File->Invalidate Caches and Restart->Invalidate and Restart

2. 如果没有运气，请File->Other Settings->Default Settings->Build, Execution, Deployment->Build Tools->Gradle->Offline work并取消选中它。
