Android Studio3.0升级gradle遇到的坑

升级了android studio3.0后，对于文件的搜索和方法中参数的使用，是一个重大的改变，但升级gradle后，缺出现很多的问题。个人整理一下，希望对大家有所帮助。

说明：我原来的环境是as2.3+gralde2.14.1+plugin2.2.3

升级后的环境是：as3.0+gradle4.2.1+plugin3.0.0

Error:(82, 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.

解决：

修改app的文件输出格式

proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

            android.applicationVariants.all { variant ->

                variant.outputs.all {

                    outputFileName = "app_V${defaultConfig.versionName}.apk"

                }

//                variant.outputs.each { output ->

//                    def outputFile = output.outputFile

//                    if (outputFile != null && outputFile.name.endsWith('.apk')) {

//                        //这里修改apk文件名

//                        def fileName = "app_V${defaultConfig.versionName}.apk"

//                        output.outputFile = new File(outputFile.parent, fileName)

//                    }

//                }

            }
