konnte nicht einmal support-annotations-25.4.0 in Maven und Jcenter-Repositories finden. Was ist das Problem?

Sieht aus wie ein Fehler von Gradel. Sie könnten versuchen, Ihrer Frage den Gradel-Tag hinzuzufügen. –

Ich tat @EricSeidel –

@EricSeidel Ich musste "Gradle 2.3.3" statt "Gradle 3.3" verwenden (3.3 wurde auf meinem System vorinstalliert). Das Herunterstufen auf 2.3.3 war die Lösung. –

Die Android Support Library Setup docs Erwähnung, dass Sie in der Lage sein können, Support-Bibliotheken über den Android SDK-Manager zu erhalten, obwohl diese Funktionalität bald entfernt wird.

Sie können die offizielle Dokumentation überprüfen.

Beginnend mit 25.4.0:

Wichtig: Die Support-Bibliotheken jetzt sind über Maven-Repository von Google. Weitere Informationen finden Sie unter Support Library Setup.

Stellen Sie sicher, dass der Abschnitt "Repositories" einen Maven-Abschnitt mit dem Endpunkt "https://maven.google.com" enthält.

allprojects { 
    repositories { 
     jcenter() 
     maven { 
      url "https://maven.google.com" 
     } 
    } 
}

Ich fand die Lösung. Unten ist ein Teil von buld.gradle Datei. Ich hatte Standard gradle (gradle 3.3 war auf meinem System) zu gradle 2.3.3 herabzustufen:

buildscript { 
    repositories { 
     jcenter() 
     maven { 
      url "https://maven.google.com" 
     } 
    } 

    dependencies { 
     classpath 'com.android.tools.build:gradle:2.3.3' 
    } 
}
