如何修复不可解析的导入 POM：com.google.cloud:spring-cloud-gcp-dependencies

Question

正在尝试从 https://github.com/GoogleCloudPlatform/spring-cloud-gcp

构建 spring-cloud-gcp

许多失败 compile/install 尝试由于失败的测试（单元和 checkstyle） - 决定只是禁用 and/or 不失败由于测试 - 太好了，工作，整个构建（所有子项目）编译
想要将 spring-cloud-gcp-data-firestore-sample（pom 在下方）部署到 Cloud 运行，因此更改了 pom 中的父引用（如 suggested/documented 在 pom 中）。
现在不能 compile/install spring-cloud-gcp-data-firestore-sample 并得到这个错误“**不可解析的导入 POM：com.google.cloud:spring-cloud-gcp-dependencies:pom:2.3.12.RELEASE 在 https://repo.maven.apache.org/maven2**"

我试过：

向 pom 添加额外的 spring maven 回购（见下面的 pom）- 运气不好，根据错误消息，maven 似乎甚至没有检查添加的回购
referencing/using 不同版本的 spring-boot-starter-parent - 运气不好，错误中没有任何变化
mvn -U clean compile - 运气不好

有人有什么想法吗？非常感谢任何建议。

您正在从 project.version 继承 com.google.cloud:spring-cloud-gcp-dependencies 的版本，在您的情况下为 2.3。12.RELEASE。

      <dependency>
        <groupId>com.google.cloud</groupId>
        <artifactId>spring-cloud-gcp-dependencies</artifactId>
        <version>${project.version}</version>
        <type>pom</type>
        <scope>import</scope>
      </dependency>

实际上，您想要指定 maven repository 中列出的有效版本。
