Firebase 身份验证错误 - 迁移项目后

Question

预期

在 IntelliJ 中运行的 Kotlin 应用程序已从 2009 款 MacBook Pro 迁移到 2019 款 MacBook Pro。如果提供相同的凭据，该项目预计会运行相同的代码访问 Firestore 数据库 和 Firestore 存储。

观察到

由于oauth错误，代码将无法在新机器上运行。

错误

1. com.google.api.gax.grpc.InstantiatingGrpcChannelProvider 未定义或继承已解析方法抽象 needsCredentials() 的实现

2. 无法检测我们是否在 Google Compute Engine 上运行。

尝试的解决方案

更新 build.gradle 中的库版本，以防问题是由于依赖冲突引起的。

build.gradle

buildscript {
    ext.kotlin_version = '1.3.41'
    ext.junitJupiterVersion  = '5.5.0'

    repositories {
        mavenCentral()
    }
    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'org.junit.platform:junit-platform-gradle-plugin:1.0.3'
    }
}

plugins {
    id 'java'
    id 'org.jetbrains.kotlin.jvm' version '1.2.51'
}

version '1.0-SNAPSHOT'

sourceCompatibility = 1.8

repositories {
    mavenCentral()
}

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8"
    testImplementation group: 'junit', name: 'junit', version: '5.3.2'
    // JUnit Jupiter API and TestEngine implementation
    testImplementation("org.junit.jupiter:junit-jupiter-api:${junitJupiterVersion}")
    testRuntime("org.junit.jupiter:junit-jupiter-engine:${junitJupiterVersion}")
    testImplementation "org.assertj:assertj-core:3.12.2"
    // To avoid compiler warnings about @API annotations in JUnit code
    testCompileOnly 'org.apiguardian:apiguardian-api:1.1.0'
    implementation 'com.squareup.retrofit2:retrofit:2.6.0'

Answer 1

这是因为“firebase-admin”通过“gax-grpc”依赖的“gax”是旧的，因此其他库（在您的情况下可能是“google-cloud-storage”）引入了较新的“gax”被 Gradle 选中，导致兼容性问题。

在我的情况下，强制 Gradle 使用最新的“gax-grpc”，如下所示可以解决问题。我希望这对你也有帮助。

implementation group: 'com.google.api', name: 'gax-grpc', version: '1.47.1'
