来自twilio：
嗨马修，
感谢您与我们联系。
看起来像＆＃34; foursquare-api＆＃34;正在引进 ＆＃34;应用服务引擎的API-1.0-SDK＆＃34;依赖性。
[INFO] +- fi.foyt:foursquare-api:jar:1.0.2:compile [INFO] | +- org.json:json:jar:20090211:compile [INFO] | \- com.google.appengine:appengine-api-1.0-sdk:jar:1.6.5:compile您可以尝试排除此依赖关系，但我希望它会 可能会破坏＆＃34; foursquare-api＆＃34;库。
＆＃34; twilio-java的＆＃34;对此没有对App Engine的硬性依赖 原因。
如果您有任何其他问题，请告诉我们。
