Nexus不通过Hudson下载文物

Question

我试图将Hudson与Nexus整合。 由于我在不使用Nexus的情况下构建项目，因此其构建成功。

当我试着使用的Nexus构建它，我得到以下编译错误：

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

这是哈德森我的配置设置：

<settings> 
    <mirrors> 
    <mirror> 
     <!--This sends everything else to /public --> 
     <id>nexus</id> 
     <mirrorOf>*</mirrorOf>

     </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> 

我不知道为什么会不从中央资源库下载到nexus公共存储库。

有人可以对此有所了解吗？

Answer 1

我终于解决了。当尝试访问中央存储库时，它被抛出为SSL异常。

这个例外是自动阻止我的访问。

我去了Central Repository> Configuration，并将远程存储位置url更改为：http://repo.maven.apache.org/maven2/，并右键单击Central并单击Allow Proxy。

之后，它就像一个魅力。

我希望这可以帮助某人，因为我几乎失去了这两天。

EDIT（19/11/2015）：

如果你正在运行使用的是RedHat/CentOS的你的OpenJDK，有一个防止通过SSL访问错误，正如指出的在评论部分@rseddon。变通办法在这里：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，这是我用了一个：

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

jdk.tls.disabledAlgorithms = EC，ECDHE，ECDH

现在我可以用我的中央回购的HTTPS链接。
