Cannot set the value of readonly property ‘outputFile‘ for ApkVariantOutputImpl_Decorated

gradle升级后，之前的打包生成apk并重命名代码出现了问题，经查一共有2个地方要修改，下边代码是修改前：

 1     applicationVariants.all { variant ->
 2         variant.outputs.each { output ->
 3             def environment = 'TUI';
 4             def oldFile = output.outputFile
 5             if (variant.buildType.name == 'release') {
 6                 def releaseApkName = 'PORSCHE_'+ defaultConfig.versionName + '_' +releaseTime()+ '_'+environment+'_release.apk'
 7                 output.outputFile = new File(oldFile.parent, releaseApkName)
 8             } else {
 9                 def debugApkName = 'PORSCHE_' + defaultConfig.versionName + '_' /*+ releaseTime()+ '_'*/+environment+'_debug.apk'
10                 output.outputFile = new File(oldFile.parent, debugApkName)
11             }
12         }
13     }

这个是修改后：

 1 applicationVariants.all { variant ->
 2         variant.outputs.each { output ->
 3             def environment = 'TUI';
 4             def oldFile = output.packageApplication.outputDirectory.toPath()
 5                     .relativize(rootDir.toPath()).toFile()
 6             if (variant.buildType.name == 'release') {
 7                 def releaseApkName = 'PORSCHE_'+ defaultConfig.versionName + '_' +releaseTime()+ '_'+environment+'_release.apk'
 8                 output.outputFileName = new File(oldFile.parent, releaseApkName)
 9             } else {
10                 def debugApkName = 'PORSCHE_' + defaultConfig.versionName + '_' /*+ releaseTime()+ '_'*/+environment+'_debug.apk'
11                 output.outputFileName = new File(oldFile.parent, debugApkName)
12             }
13         }
14     }

第一处：output.outputFile = 改成 output.outputFileName =

第二处：def oldFile = output.outputFile 改成 output.packageApplication.outputDirectory.toPath()
.relativize(rootDir.toPath()).toFile()

否则就会报 Absolute path are not supported when setting an output file name 错误
