Question

我在尝试使用Maven构建项目时遇到了问题，更具体地说，当需要依赖关系时，即Oracle JDBC 7，我一直在寻找解决方案，花费了数小时之久，甚至什么也没有，甚至咨询了有关该问题的一些问题。在这里，但什么都没有

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

行家路线是什么：

C：\用户\ E10697 \ .m2 \信息库\ 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>

该仓库在Maven仓库页面上列出： 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，添加回购协议和确切版本的组合对我来说很有效。

尝试将ojdbc7安装为Maven依赖项时出现问题
