Question

开始尝试使用我的网络应用程序使用Firebase Auth。以下步骤成功：

使用电子邮件密码登录
检索idToken
将idToken发送到我的服务器进行验证

在我的StartupListener我正在初始化FirebaseApp，如下所示：

serviceAccount = new FileInputStream(root +
    "/WEB-INF/classes/<projid>-firebase-adminsdk-ojzbs-<some-number>.json");

FirebaseOptions options = new FirebaseOptions.Builder()
    .setCredential(FirebaseCredentials.fromCertificate(serviceAccount))
    .setDatabaseUrl("https://<projid>.firebaseio.com").build();

FirebaseApp fibApp = FirebaseApp.initializeApp(options);

此代码不会抛出任何异常，因此假设它正常工作。

我的API调用中的以下行会抛出NoSuchMethodError：

FirebaseAuth fibAuth = FirebaseAuth.getInstance();

我在Firebase控制台中启用了电子邮件/密码身份验证。使用Firebase Admin SDK 4.1.7版（Java）。该代码在Google App Engine（标准环境）上运行。

使用Guava 19.0。

Answer 1

我对此问题的解决方法是从firebase管理库中排除guava并手动导入，如下所示：

compile ('com.google.firebase:firebase-admin:5.0.0') {
    exclude group: 'com.google.guava'
}
compile 'com.google.guava:guava:21.0'

问题是firebase管理库使用了两个不同版本的Guava 17和20

Answer 2

解决方案是将Guava从版本19.0升级到20.0。

PS：不能使用Guava 21.0，因为到目前为止GAE仅支持GA中的Java 7。

Answer 3

如果您使用的是mvn dependency:tree > output.txt之类的Maven检查依赖树

排除依赖冲突。我的案例专家，docker Spotify插件oauth2库与firebase冲突。

POM示例：

      <dependency>
        <groupId>com.spotify</groupId>
        <artifactId>dockerfile-maven-plugin</artifactId>
        <!--google-auth-library-oauth2-http conflict with firebase -->
        <exclusions>
            <exclusion>
                <groupId>com.google.guava</groupId>
                <artifactId>guava</artifactId>
            </exclusion>
            <exclusion>
                <groupId>com.google.auth</groupId>
                <artifactId>google-auth-library-oauth2-http</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

    <!-- https://mvnrepository.com/artifact/com.google.firebase/firebase-admin -->
    <dependency>
        <groupId>com.google.firebase</groupId>
        <artifactId>firebase-admin</artifactId>
        <version>6.7.0</version>
    </dependency>
