尝试将 ojdbc7 安装为 maven 依赖项的问题

Question

我在尝试使用 maven 构建我的项目时遇到问题，更具体地说，当需要依赖项时，即 Oracle JDBC 7 的依赖项，我一直在寻找解决方案几个小时却一无所获，甚至在此处咨询了一些与此相关的问题，但一无所获

C:\Users\E10697\Desktop\Contenedores\oracle_contenedores\Entorno-Oracle-sobre-Docker-master\4. Consumo de la Oracle DB a traves de un API Rest\4.1。Elaboración del API Rest\4.1.2。实现 API Rest\OpenwebinarDockerAPI - RESUELTO\OPENWE~1>mvn clean install

错误：[错误] 无法在项目 app-rest-api 上执行目标：无法解析项目 openwebinar.marvel.app:app-rest-api:war:0.1.0-SNAPSHOT：找不到工件 com.oracle 的依赖项:ojdbc7:jar:12.1.0 在 spring-milestones ( https://repo.spring.io/milestone )

我的项目结构，在这种情况下，我在operwebinar_mavel文件夹中运行 mvn clean install 命令：

Maven 路线中有什么：

C:\Users\E10697\.m2\repository\com\oracle\ojdbc7\12.1.0

Answer 1

将存储库添加到您的 POM 中，它将起作用：

<repositories>
    <repository>
        <id>hand-china-repo</id>
        <name>HandChinaRepo</name>
        <url>http://nexus.saas.hand-china.com/content/repositories/rdc/</url>
    </repository>
</repositories>

该存储库列在 Maven 存储库页面上：https : //mvnrepository.com/artifact/com.oracle/ojdbc7/12.1.0.2

Maven Central 在 12.1.0.2 版本中报告了类似的依赖项。尝试更改您的 POM 以匹配：

<!-- https://mvnrepository.com/artifact/com.oracle/ojdbc7 -->
<dependency>
    <groupId>com.oracle</groupId>
    <artifactId>ojdbc7</artifactId>
    <version>12.1.0.2</version>
</dependency>

我测试过，这种添加 repo 和确切版本的组合对我有用。
