如果你的classPath>3.0 会报错 应当使用

applicationVariants.all { variant ->    //批量修改Apk名字                variant.outputs.all { output ->                    if (!variant.buildType.isDebuggable()) {                        //获取签名的名字 variant.signingConfig.name                        //要被替换的源字符串                        def sourceFile = "-${variant.flavorName}-${variant.buildType.name}"                        //替换的字符串                        def replaceFile = "gxb_v${variant.versionName}_${variant.productFlavors[0].name}_${variant.buildType.name}"                        outputFileName = output.outputFile.name.replace(sourceFile, replaceFile);                    }                }            }
