WARNING: API 'variantOutput.getPackageApplication()' is obsolete and has been replaced with 'variant.getPackageApplicationProvider()'.

将代码

applicationVariants.all { variant ->
    if (variant.buildType.name.equals('release')) {
        variant.outputs.all { output ->
            def outputFile = output.outputFile
            if (outputFile != null && outputFile.name.endsWith('.apk')) {
                outputFileName = "Terminator${defaultConfig.versionName}.apk"
            }
        }
    } else if (variant.buildType.name.equals('debug')) {
        variant.outputs.all { output ->
            def outputFile = output.outputFile
            if (outputFile != null && outputFile.name.endsWith('.apk')) {
                outputFileName = "Terminator${defaultConfig.versionName}${versionNameSuffix}.apk"
            }
        }
    }
}

改为

applicationVariants.all { variant ->
                if (variant.buildType.name.equals('release')) {
                    variant.outputs.all { output ->
                        outputFileName = "Terminator${variant.versionName}_${releaseTime()}.apk"
//                        def outputFile = output.outputFile
//                        if (outputFile != null && outputFile.name.endsWith('.apk')) {
//                            outputFileName = "Terminator${defaultConfig.versionName}.apk"
//                        }
                    }
                } else if (variant.buildType.name.equals('debug')) {
                    variant.outputs.all { output ->
                        outputFileName = "Terminator${variant.versionName}_${releaseTime()}.apk"
//                        def outputFile = output.outputFile
//                        if (outputFile != null && outputFile.name.endsWith('.apk')) {
//                            outputFileName = "Terminator${defaultConfig.versionName}${versionNameSuffix}.apk"
//                        }
                    }
                }
            }
