【AndroidStudio】3.0升級gradle遇到的坑
阿新 • • 發佈：2019-01-04
升級了android studio3.0後，對於檔案的搜尋和方法中引數的使用，是一個重大的改變，但升級gradle後，缺出現很多的問題。個人整理一下，希望對大家有所幫助。
說明：我原來的環境是as2.3+gralde2.14.1+plugin2.2.3
升級後的環境是：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.<a href="openFile:G:\Work\Svn\BetaSVN\Tech\Beta.Android\Src\BCP\app\build.gradle">Open File</a>
解決：
修改app的檔案輸出格式
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
android.applicationVariants.all { variant ->
variant.outputs.all {
outputFileName = "app_V${defaultConfig.versionName}.apk"
}
// variant.outputs.each { output ->
// def outputFile = output.outputFile
// if (outputFile != null && outputFile.name.endsWith('.apk')) {
// //這裡修改apk檔名
// def fileName = "app_V${defaultConfig.versionName}.apk"
// output.outputFile = new File(outputFile.parent, fileName)
// }
// }
}

修改辦法同第一個
7、
Error:Unable to load class 'org.gradle.api.internal.component.Usage'.
Possible causes for this unexpected error include:<ul><li>Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.)
<a href="syncProject">Re-download dependencies and sync project (requires network)</a></li><li>The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem.
<a href="stopGradleDaemons">Stop Gradle build processes (requires restart)</a></li><li>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.</li></ul>In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes.
解決：
a.修改gradle的版本
b.增加google() 修改版本號
buildscript {
repositories {
jcenter()
google()
}
dependencies {
...
classpath 'com.novoda:bintray-release:0.5.0'//修改此處版本號為 0.5.0---修改之前是0.3.4
...
}
}8、
Error:No such property: FOR_RUNTIME for class: org.gradle.api.attributes.Usage
解決：
將gradle的版本從4.3.1降級到4.2.1
