Sonatype Nexus的安装配置参见：CentOS系统中安装Nexus并导入已有的构件库。Nexus内置了Jetty容器，${NEXUS_HOME}/bin/jsw目录下包含了各个操作系统的启动脚本。当然，如果你不喜欢内置的Jetty容器，也可以下载Nexus的war包，部署在tomcat等容器中。
安装部署后，比较重要的是能够对其进行深入的管理和配置，本文将介绍一些关于Sonatype Nexus的高级配置技巧，方便您进行配置管理。
<server> <id>thirdparty</id> <username>deployment</username> <password>password</password> </server>
默认情况下，Nexus监听端口8081。可以通过以下方法更改这个端口。
Nexus默认支持jar、war、pom、ejb、ear、rar、par等类型的包，如果希望能添加一些其它类型的包，可以配置如下：
在${nexus-work}/conf/packaging2extension-mapping.properties配置文件中增加配置：
my-custom-packaging=myextension |
如果该配置文件不存在则手动创建该文件。
1）强制更新索引
nexus索引经常会出现与远程仓库索引不一致的情况，导致某些包不能正常下载，可以强制更新仓库索引，保持索引同步：
2）定时更新索引
如果Nexus本地索引中包含组件，但是却不能下载，可能的原因如下：
Nexus提供了可以调试组件下载过程的方法，在组件的下载全路径后面增加参数“?describe”，示例如下：
http://localhost:8081/nexus/content/groups/public/foo/bar/1.0/bar-1.0.jar?describe
Nexus将会以json的形式返回调试的输出结果，结果主要包括：
示例返回结果如下：
{
"data":{
"requestUrl":"http://localhost:8081/nexus/content/groups/public/test/project/1.0/project-1.0.jar?describe",
"processingTimeMillis":471,
"request":{
"requestUrl":"http://localhost:8081/nexus/content
/groups/public/test/project/1.0/project-1.0.jar?describe",
"requestPath":"/test/project/1.0/project-1.0.jar",
"requestContext":[
"request.received.timestamp=1276286536595",
"request.address=0:0:0:0:0:0:0:1%0",
"request.remoteOnly=false",
"request.url=http://localhost:8081/nexus/content/groups/public/test/project/1.0/project-
1.0.jar?describe",
"request.localOnly=false",
"request.appRootUrl=http://localhost:8081/nexus"
]
},
"response":{
"responseType":"NOT_FOUND",
"processedRepositoriesList":[
"public",
"snapshots",
"thirdparty",
"central",
"java.net-m2",
"java.net-m1-m2",
"google",
"apache-snapshots",
"codehaus-snapshots"
],
"appliedMappings":[
"public repository applied [11b647d6117038d8=
[type=EXCLUSION, groupId=public, patterns=[.*/project/.*], mappedRepositories=[releases]]]"
]
}
}
}
注意查看其中的response节点，如上例中的"responseType":"NOT_FOUND"表示未找到组件，通过该方法可以详细排查组件不能下载的原因。
再提供一个pom类型的包“mojo-parent-30.pom”的调试示例
