我不加apply plugin: 'maven-publish',报如下错误：
Error:Execution failed for task ':EasyAndroid:bintrayUpload'.
Extension of type 'PublishingExtension' does not exist. Currently registered extension types: [DefaultExtraPropertiesExtension, DefaultArtifactPublicationSet_Decorated, ReportingExtension_Decorated, LibraryExtension_Decorated, BintrayExtension_Decorated]
加了之后，上述错误没有了，但是出现这个问题。我翻墙了还是报错
bintrayUpload'. java.net.SocketException: Software caused connection abort: socket write error
我使用这个：apply plugin: 'com.novoda.bintray-release'，依然报错
bintrayUpload: Could not find publication: release.
（虽然下句提示succeed，但是到Bintray查看，只有个空版本，什么都没上传上去）
bintrayUpload: SUCCEED
