升级到java 8后无法使用crashlytics释放项目

移动到java 8 ,我在应用程序发布中遇到此错误,因为fabric崩溃:

 Could not determine the dependencies of task ':app:crashlyticsStoreDeobsRelease'. > Task with path 'dexRelease' not found in project ':app'. 

我使用的是Android Studio 2.2Gradle version 2.14.1 ,Android插件版本2.2.0

项目运行没有任何问题,但我无法生成签名的apk!

我读过这篇文章无法运行项目 – Android Studio 2.0 Crashlytics问题并且无法确定任务的依赖关系’:app:crashlyticsStoreDeobsDebug’如果我启用了proguard但回答没有帮助我。

这是我的gradle文件:

 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 { maven { url 'https://maven.fabric.io/public' } } android { compileSdkVersion 24 buildToolsVersion "24.0.2" defaultConfig { applicationId "..." minSdkVersion 16 targetSdkVersion 22 versionCode 17 versionName "0.14.1" jackOptions { enabled true } } compileOptions { sourceCompatibility JavaVersion.VERSION_1_8 targetCompatibility JavaVersion.VERSION_1_8 } dexOptions { javaMaxHeapSize "3g" } signingConfigs { release { storeFile file("....jks") storePassword "..." keyAlias "..." keyPassword "..." } } buildTypes { release { minifyEnabled true proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' shrinkResources true debuggable true signingConfig signingConfigs.release } debug{ debuggable true //applicationIdSuffix ".debug" } } } dependencies { compile fileTree(include: ['*.jar'], dir: 'libs') //Material edit text compile 'com.rengwuxian.materialedittext:library:2.1.4' //Circle progress bar compile 'com.github.castorflex.smoothprogressbar:library-circular:1.1.0' //a divider for recyclerview compile 'com.yqritc:recyclerview-flexibledivider:1.2.9' //Field and method binding for Android views compile 'com.jakewharton:butterknife:7.0.1' //crash reporting and streamline solution for distributing apps compile('com.crashlytics.sdk.android:crashlytics:2.6.3@aar') { transitive = true; } //LeakCanary debugCompile 'com.squareup.leakcanary:leakcanary-android:1.4-beta2' releaseCompile 'com.squareup.leakcanary:leakcanary-android-no-op:1.4-beta2' testCompile 'com.squareup.leakcanary:leakcanary-android-no-op:1.4-beta2' compile('com.github.ozodrukh:CircularReveal:2.0.1@aar') { transitive = true; } compile project(':core') } apply plugin: 'com.google.gms.google-services' 

我从这个链接检查了Fabric工具版本

https://s3.amazonaws.com/fabric-artifacts/public/io/fabric/tools/gradle/maven-metadata.xml

然后我使用了较低版本的classpath 'io.fabric.tools:gradle:1.25.4'
