output.packageApplication.outputDirectory.toPath () - не строить

Question

Android Studio 3.5

classpath 'com.android.tools.build:gradle:3.6.0-beta01'

в app / build.gradle:

            def releaseOutputFileName = "${rootProject.name}_${defaultConfig.versionName}.apk"
            def packageAppOutputDirPath = output.packageApplication.outputDirectory.toPath()

Но я получаю ошибку:

com.android.build.gradle.internal.crash.ExternalApiUsageException: groovy.lang.MissingMethodException: No signature of method: org.gradle.api.internal.file.DefaultFilePropertyFactory$DefaultDirectoryVar.toPath() is applicable for argument types: () values: []
