为什么我的 maven 项目没有从 nexus 中获取 jar

Question

我在 Redhat，使用 jenkins 和 Nexus Repository Manager OSS 2.12.0-01。

我想要实现的是从nexus 下载所有的jar。什么，我已经完成了。安装成功nexus 2.12.0-01

这是我maven的内容setting.xml

已成功在 nexus 中安装 Ojdbc5 的第 3 方 jar

我父 pom 的内容

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

    </snapshotRepository>

    <repository>

        <url>http://localhost:8081/nexus/content/repositories/releases</url>
    </repository>

</distributionManagement>
</project>

在上面pom.xml中定义了两个项目。当我使用 jenkins 构建时，第一个项目成功构建。但第二个抛出错误。

Failed to execute goal on project project2: Could not resolve dependencies for project com.abc:project2:war:0.0.1-SNAPSHOT: Failure to find com.oracle:ojdbc5:jar:11.2.0.1 in http://localhost:8081/nexus/content/groups/public was cached in the local repository, resolution will not be reattempted until the update interval of nexus has elapsed or updates are forced -> [Help 1]

请看项目2 pom.xml

        <!-- ojdbc 5 dependency provide by nexus-->

         <version>11.2.0.1</version>
        </dependency>
    <!-- That is creating problem -->

请不要担心上面的问题 pom.xml 我已经从 pom 中删除了很多依赖项以减少问题的大小。 pom结构没问题

现在开始质疑。我是否错过了任何配置，为什么我得到

Failed to execute goal on project gsdataprocessor: Could not resolve dependencies for project com.globalss.batch:gsdataprocessor:war:0.0.1-SNAPSHOT: Failure to find com.oracle:ojdbc5:jar:11.2.0.1 in http://localhost:8081/nexus/content/groups/public was cached in the local repository, resolution will not be reattempted until the update interval of nexus has elapsed or updates are forced -> [Help 1]

这个错误。请帮忙

更新 1：根据用户 sanigo 的建议，我已将第三方存储库添加到 Public 存储库组

更新 2：下面是显示 oracle ojdbc5 可用的屏幕截图是 public 存储库。

Answer 1

您的 http://localhost:8081/nexus/content/groups/public (Public Repository Group) is mirror of "*", so you should add http://localhost:8081/nexus/content/repositories/thirdparty(Thirdparty 存储库）到 [=14th=] 存储库组，您可以在 Public 存储库配置选项卡中执行此操作。然后你可以使用 mvn -U clean install.
