Question

我正在尝试在pom.xml中添加firebase-admin依赖项：

<dependency>
  <groupId>com.google.firebase</groupId>
  <artifactId>firebase-admin</artifactId>
  <version>6.6.0</version>
</dependency>

但是当我尝试使用“全新安装”命令构建项目时，出现以下错误：

我尝试通过显式添加grpc-core的依赖项：

<dependency>
    <groupId>io.grpc</groupId>
    <artifactId>grpc-core</artifactId>
    <version>1.13.1</version>
</dependency>

此jar已下载到我的本地存储库，但对于firebase-admin仍然存在相同的错误。

如何克服此错误？

Answer 1

我通过在依赖项管理中覆盖grpc-core来解决了这个问题：

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>io.grpc</groupId>
            <artifactId>grpc-core</artifactId>
            <version>1.13.1</version>
        </dependency>
        <dependency>
            <groupId>com.google.firebase</groupId>
            <artifactId>firebase-admin</artifactId>
            <version>6.6.0</version>
        </dependency>
    </dependencies>
</dependencyManagement>

<dependencies>
    <dependency>
        <groupId>com.google.firebase</groupId>
        <artifactId>firebase-admin</artifactId>
    </dependency>
</dependencies>

顺序很重要。希望这会有所帮助。

Answer 2

我有同样的问题。我能够通过从本地repo目录中删除maven-metadata来解决此问题（针对相关的依赖项）。

即：

user_dir\.m2\repository\io\grpc\grpc-api

maven-metadata-central.xml
maven-metadata-central.xml.sha1
resolver-status.properties

在Eclipse中添加firebase-admin maven依赖项时出现“在指定范围内io.grpc：grpc-core：jar：[1.13.1]没有可用的版本”错误
