更新Gradle之后，我得到了这个错误（我在更新Gradle的同时还添加了maven {jitpack.io}和geofirestore依赖项）：

我该如何解决？
这是我的Project构建包：
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.2.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
classpath 'com.google.gms:google-services:4.0.2'
}
}
allprojects {
repositories {
google()
jcenter()
maven { url 'https://jitpack.io' }
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
和我的模块构建gradle：
apply plugin: 'com.android.application'
android {
compileSdkVersion 27
defaultConfig {

minSdkVersion 21
targetSdkVersion 27

我使用的是最新版本的android studio，并且在升级gradle之前，我的项目可以正常运行。

答案 1 :(得分：8)
将gradle版本降级为3.1.4，即classpath'com.android.tools.build:gradle:3.1.4'
答案 2 :(得分：6)
在3.1.4上降级gradle。 检查您的 build.gradle （Modele：App）文件：
convert_model_krs_tfjs.py
-------------------------
import keras
from keras.models import model_from_json
from keras.optimizers import SGD
import numpy as np
from time import sleep
import tensorflowjs as tfjs
model = model_from_json(open('Face_model_architecture.json').read())
model.load_weights('Face_model_weights.h5')
sgd = SGD(lr=0.1, decay=1e-6, momentum=0.9, nesterov=True)
model.compile(loss='categorical_crossentropy', optimizer=sgd)
model.save("Keras-64x2-10epoch")
tfjs.converters.save_keras_model(model, "face")
My python worked code:

检查您的 graddle-wrapper.properties 文件
Sun Jul 08 23:40:54 KST 2018
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip
检查gradle版本文件url的最后一行
答案 4 :(得分：3)
在此build.gradle中尝试此代码
classpath 'com.android.tools.build:gradle:3.1.4'
答案 5 :(得分：2)
将您的类路径设置为当前的构建gradle，并同步您的项目。AndroidStudio 3.2版似乎存在问题。当提示更新gradle时，还更新了classpath值。
答案 6 :(得分：2)
对于我来说，在更新到新的gradle 3.0.1至3.2.0之后，今天遇到了这个问题，我删除了values文件夹中的ids.xml文件（在项目中没有用）对我来说有用
