Android Studio 3.0 升级编译错误分析

今天Google推送了Android Studio 3.0的升级

升级完了以后，AS要求将

gradle tools升级到3.0.0

classpath 'com.android.tools.build:gradle:3.0.0'

gradle也升级到gradle-4.1-all.zip

升级完了以后，编译就出现各种问题

问题1

Error:(130, 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

原来用来重命名打包后的apk方法不能用了

原来的方法

variant.outputs[0].outputFile = new File(apkDir, filename)

要改成下面的方法

variant.outputs.all {output -> outputFileName = filename }

问题2

2. Error:Cannot choose between the following configurations of project :videoplayer:
      - debugApiElements
      - debugRuntimeElements

以前Android Studio不会自动匹配Library中的BuildTypes

3.0以后 现在就可以自动匹配了（只要app选择了debug，后面会自动选中debug，release也是一样）

当然 需要注意的是 Library中需要添加buildTypes跟app的一样，

比如App中有 release debug debugTest

那么Library中也要有这3个

直接空着也没关系

问题3

如果你用了类似butterknife

需要做如下改动

project的build.gradle文件中删除

• classpath ‘com.neenbedankt.gradle.plugins:android-apt:1.8’

module的build.gradle文件中删除

• apply plugin: ‘android-apt’

module的build.gradle文件中替换

//apt 'com.jakewharton:butterknife-compiler:8.4.0'
annotationProcessor 'com.jakewharton:butterknife-compiler:8.4.0'

解决办法：

在Project/gradle.properties中添加 android.enableAapt2=false
