Android(安卓)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.
Open File
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)
// }
// }
}

7、
Error:Unable to load class 'org.gradle.api.internal.component.Usage'.
Possible causes for this unexpected error include:

Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.)
Re-download dependencies and sync project (requires network)
The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem.
Stop Gradle build processes (requires restart)
Your project may be using a third-party plugin which is not compatible with the other plugins in the project or the version of Gradle requested by the project.

In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes.
解决：
修改gradle的版本

解决：
将gradle的版本从4.3.1降级到4.2.1
