Question

我尝试了在互联网上找到的所有解决方案，但仍然收到以下错误：

Failed to resolve: com.google.firebase:firebase-core:16.0.5

可能是什么原因？我已经检查了所有实施列表是否完整以及正确的版本。我也检查了类路径和其他所有内容。但是什么都行不通！

build.grande（模块）

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    defaultConfig {
        applicationId "com.example.ves.gennaio3"

build.grandle（项目）

// Top-level build file where you can add configuration options common to all sub-projects/modules.

task clean(type: Delete) {
    delete rootProject.buildDir

Answer 1

从https://firebase.google.com/docs/android/setup起，看来16.0.4是最新版本

com.google.firebase:firebase-core:16.0.4

Answer 2

@Johns解决方案不适用于我们，因为我们遇到了该版本的另一个已知问题（请参见https://developers.google.com/android/guides/releases）

对我们有用的是使用firebase-core的别名：

将POST <your_index_name>/_search { "query":{ "bool":{ "should":[ { "bool":{ "boost":100, "must":[ { "multi_match":{ "query":"....", "analyzer":"simple", "fuzziness":"AUTO", "use_dis_max":false, "fields":[ "name*" ] } }, { "type":{ "value":"C" } } ] } }, { "bool":{ "boost":5, "must":[ { "type":{ "value":"D" } }, { "multi_match":{ "query":"....", "analyzer":"simple", "fuzziness":0, "use_dis_max":false, "fields":[ "name*" ] } }, { "multi_match":{ "query":"....", "analyzer":"simple", "fuzziness":3, "fields":[ "name*" ] } } ] } } ] } } }更改为

com.google.firebase:firebase-core:16.0.4

无法解决：com.google.firebase：firebase-core：16.0.5
