Nexus 不通过 Hudson 下载工件

Question

我正在尝试将 Hudson 与 Nexus 集成。当我在不使用 Nexus 的情况下构建项目时，它的构建是成功的。

当我尝试使用 Nexus 构建它时，出现以下构建错误：

Apache Maven 3.1.1 (0728685237757ffbf44136acec0402957f723d9a; 2013-09-17 12:22:22-0300)

这是我在 Hudson 上配置的设置：

<settings>
  <mirrors>
    <mirror>
      <!--This sends everything else to /public -->
      <id>nexus</id>
      <mirrorOf>*</mirrorOf>
      <url>http://localhost:8081/nexus/content/groups/public</url>
    </mirror>
  </mirrors>
  <profiles>
    <profile>
      <id>nexus</id>
      <!--Enable snapshots for the built in central repo to direct -->
      <!--all requests to nexus via the mirror -->

      </repositories>

        <pluginRepository>

          <releases><enabled>true</enabled></releases>
          <snapshots><enabled>true</enabled></snapshots>
        </pluginRepository>
      </pluginRepositories>
    </profile>
  </profiles>
  <activeProfiles>
    <!--make the profile active all the time -->
    <activeProfile>nexus</activeProfile>
  </activeProfiles>
  <servers>
    <server>
      <id>nexus</id>
      <username>admin</username>
      <password>admin123</password>
    </server>
  </servers>
</settings>

我不知道为什么它不从中央存储库下载到 nexus public 存储库。

有人可以解释一下吗？

Answer 1

我终于解决了。尝试访问中央存储库时抛出 SSL 异常。

此异常自动阻止了我的访问。

我转到中央存储库 > 配置并将远程存储位置 url 更改为：http://repo.maven.apache.org/maven2/ 并右键单击中央并单击允许代理。

在那之后它就像一个魅力。

我希望这对某人有所帮助，因为我为此浪费了将近两天的时间。

编辑（2015 年 11 月 19 日）：

如果您运行您的 openjdk 使用 RedHat/CentOS，则存在阻止通过 SSL 访问的错误，正如 @rseddon 在评论部分中指出的那样。解决方法在这里：https://issues.sonatype.org/browse/NEXUS-7999?focusedCommentId=306680&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-306680

如果你赶时间，我用的是这个：

将以下行添加到 ${JAVA_HOME}/jre/lib/security/java.security :

jdk.tls.disabledAlgorithms=EC、ECDHE、ECDH

现在我可以在我的 Central Repo 上使用 https link。
