java - 尝试将 ojdbc7 安装为 Maven 依赖项时出现问题

Question

我在尝试使用 Maven 构建项目时遇到问题，更具体地说，当需要依赖项时，Oracle JDBC 7 的依赖项，我一直在寻找解决方案几个小时，但一无所获，甚至咨询了有关该问题的一些问题这里什么都没有

C:\Users\E10697\Desktop\Contenedores\oracle_contenedores\Entorno-Oracle-sobre-Docker-master\4。 Oracle DB 的使用来自 API Rest\4.1。 API Rest 详细说明\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 的依赖项:可以在 spring-milestones ( https://repo.spring.io/milestone ) 中找不到 Artifact com.oracle:ojdbc7:jar:12.1.0

我的项目结构，在本例中，我在 operwebinar_mavel 文件夹中运行 mvn clean install 命令:

maven 路由中有什么:

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 在版本 12.1.0.2 中报告了类似的依赖关系。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>

我进行了测试，添加存储库和确切版本的这种组合对我来说很有效。
