在不同電腦Android Studio上運行同一個專案，出現

Could not find support-fragment.jar (com.android.support:support-fragment:27.1.1).
Searched in the following locations:
    https://jcenter.bintray.com/com/android/support/support-fragment/27.1.1/support-fragment-27.1.1.jar

解決這個問題只需要在build.gradle檔案裡修改allprojects 裡面的repositories，把google放到jcenter前面就可以了

原檔案

allprojects {
    repositories {
        jcenter()
        mavenCentral()
        maven { url 'https://maven.google.com' }
        maven { url "https://dl.google.com/dl/android/maven2/"
 
}
    }
}

修改後

allprojects {
    repositories {
        maven { url 'https://maven.google.com' }
        jcenter()
        mavenCentral()
        maven { url "https://dl.google.com/dl/android/maven2/"}
    }
}
