自建maven仓库 和使用 搭建maven私有仓库

1、首先下载nexus，下载地址是http://www.sonatype.org/nexus/go，在此页面可以下载最新版本的Nexus;

2、解压下载的zip包，安装Nexus，由于下载的zip包自带jetty,在cmd命令模式下 到Nexus的安装目录，执行命令nexus.bat install命令安装nexus

3、然后运行nexus.bat start命令启动nexus（其他命令有nexus.bat stop停止 nexus.bat restart重启 nexus.bat uninstall卸载）

在浏览器地址栏输入http://localhost:8080/nexus/即进入nexus首页。有管理nexus要以管理员身份登录，点击首页右上角的login输入默认登录名、密码admin/admin123即可登录。

登录系统后点击左侧菜单栏Views/Repositories下的Repositories选择Central仓库点击下边的Configuration把Download Remote Indexes属性设为True保存即可。

然后在Central仓库上右键然后点击Repair Index 即可下载中心仓库的索引文件，稍等几分钟点击下边的Browse Index即可看见下载的索引文件。

往Public Repositories中添加Central仓库，点击Public Repositories在Configuration选项卡中把Central移到左侧即可。

 

 

最后在自己的应用中把中心仓库配置成建立的私有仓库地址即可，修改本地的maven配置文件，C:\Documents and Settings\用户名\.m2\setting.xml

Nexus启动报错： Unsupported major.minor version 51.0

1.遇到问题

   今天搭建Nexus私服，出现了以前没遇到过的错误。

    a).采用console-nexus.bat开启报错：

2.分析问题

   看日志的问题，大概就是版本存在问题，找不到Java虚拟机。

   Java版本：1.6.0_45

   Nexus版本： 2.7.2-03

   按照网上的办法是修改bin\jsw\conf\wrapper.conf中的wrapper.java.command

wrapper.java.command=C:\Lynch\Develop\Java\jdk1.6\bin\java.exe

   指向自己的jdk，似乎在特俗的Nexus版本可以解决，这里我还是不行。

3.解决问题

   最终查询文档得到思路

Sonatype Nexus 2.6.0 Java 6 Support EOL Oracle's support for Java 6 ended in February 2013. Consequentially as of version 2.6 Nexus now requires a Java 7 JRE to run.

   a).Nexus的2.6版本及其以后版本

       使用的Java的jdk7.

   b).Nexus的2.0-2.5版本

       使用Java的jdk6的update30版本及其以后的jdk6版本

       使用Java的jdk7的update2版本及其以后jdk7版本

   c).最终解决方案

       升级jdk7（注意jdk的update版本，升级最新版本就可以）
