如何解决“classl failed resolve com.theartofdev.edmodo：android-image-cropper：”

我安装了新版Android Studio“2.1.0.9”.现在当同步gradle错误信息时：

gradel Failed resolve com.theartofdev.edmodo:android-image-cropper:+

我使用任何版本的图像裁剪器,但仍然有这个消息.
gradle这个：

buildscript {
repositories {
    maven { url 'https://maven.fabric.io/public' }
}

dependencies {
    classpath 'io.fabric.tools:gradle:1.+'
}
}
apply plugin: 'com.android.application'
apply plugin: 'io.fabric'

repositories {
mavenCentral()
jcenter()
maven { url 'https://maven.fabric.io/public' }
}
dependencies {
compile filetree(include: ['*.jar'], dir: 'libs')
compile 'com.android.support:support-v4:23.1.1'
compile 'com.google.android.gms:play-services:8.4.0'
compile 'com.github.dmytrodanylyk.circular-progress-button:library:1.1.3'
compile 'com.theartofdev.edmodo:android-image-cropper:2.0.+'
compile 'com.squareup.picasso:picasso:2.5.2'
compile 'com.squareup.okhttp:okhttp-urlconnection:2.5.0'
}
android {
compileSdkVersion 'Google Apis:Google Apis:23'
buildToolsversion '23.0.2'
useLibrary 'org.apache.http.legacy'
compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_7
    targetCompatibility JavaVersion.VERSION_1_7
}
defaultConfig {  
    minSdkVersion 14
    targetSdkVersion 23
}

解决方法:

你应该用这个替换依赖

compile 'com.theartofdev.edmodo:android-image-cropper:2.3.1'

这个对我有用
