Ich verwende Android Studio 2.0 unter Windows 7. Beim Erstellen meines Android-Projekts wird die folgende Fehlermeldung angezeigt:

:app:transformResourcesWithMergeJavaResForDebug FAILED

Ich habe stundenlang herumgegraben und kann nichts sehen, was dies verursacht. Ich habe .gradle in meinem Home-Verzeichnis gelöscht, es wird jedoch trotzdem neu erstellt. Weiß jemand woran das liegt?

Soweit ich das beurteilen kann, liegt ein Konflikt zwischen zwei Abhängigkeiten vor:

dependencies {
  appengineSdk 'com.google.appengine:appengine-java-sdk:1.9.28'
  compile 'com.google.appengine:appengine-endpoints:1.9.28'
  compile 'com.google.appengine:appengine-endpoints-deps:1.9.28'
  compile 'javax.servlet:servlet-api:2.5'
  compile 'com.google.http-client:google-http-client-jackson2:1.20.0'
  compile 'com.google.http-client:google-http-client-gson:1.19.0'
}

Ich denke, es sind diese zwei Abhängigkeiten:

appengineSdk 'com.google.appengine:appengine-java-sdk:1.9.28'
compile 'com.google.appengine:appengine-endpoints:1.9.28'
compile 'com.google.appengine:appengine-endpoints-deps:1.9.28'

Ich kann keine davon entfernen, da dies Kompilierungsfehler auf dem Backend-Modul verursacht. Es sieht jedoch so aus, als wären diese beiden Abhängigkeiten fast identisch. Sollten sie beide da drin sein? Jeder Rat ist willkommen!
