这是我的build.gradle的片段:

compile 'com.google.api-client:google-api-client:1.19.0'
compile 'com.google.apis:google-api-services-oauth2:v2-rev77-1.19.0'
compile 'com.google.apis:google-api-services-plus:v1-rev155-1.19.0'
compile 'com.google.appengine.tools:appengine-gcs-client:0.4.1'
compile 'com.google.appengine.tools:appengine-mapreduce:0.8'

使用dependencyInsight可以看到导入多个版本的guava:
