错误信息
Error:(37, 0) Cannot set the value of read-only property 'outputFile' for ApkVariantOutputImpl_Decorated{apkData=Main{type=MAIN, fullName=debug, filters=[]}} of type com.android.build.gradle.internal.api.ApkVariantOutputImpl.

修改你app模块(不是android工程下的)下的build.gradle
android.applicationVariants.all { variant ->
variant.outputs.all {
outputFileName = "${variant.name}-${variant.versionName}.apk"
}
}butterknife相关
错误信息
Error:Execution failed for task ':wigetlib:javaPreCompileDebug'.
> Annotation processors must be explicitly declared now. The following dependencies on the compile classpath are found to contain annotation processor. Please add them to the annotationProcessor configuration.
- butterknife-7.0.1.jar (com.jakewharton:butterknife:7.0.1)
Alternatively, set android.defaultConfig.javaCompileOptions.annotationProcessorOptions.includeCompileClasspath = true to continue with previous behavior. Note that this option is deprecated and will be removed in the future.
See https://developer.android.com/r/tools/annotation-processor-error-message.html for more details.解决方法
修改app模块下的build.gradle,在defaultConfig标签下增加javaCompileOptions
defaultConfig {
applicationId "com.xugaoxiang.demo"
minSdkVersion 15
targetSdkVersion 25
versionCode 2
versionName "1.0.2"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
javaCompileOptions {
annotationProcessorOptions {
includeCompileClasspath = true
}
}
}android studio 3.0.1版本增加了第三方库更新的提示，butterknife已经升级到了8.6.0，除了上述解决方法，你还可以通过更新库的方式来解决，只不过需要去修改代码了，很多API已经不适用了。
