Nexus:
nexus\bin\jsw\windows-x86-64\install-nexus #install it to Wndows Service.
目前较快的maven镜像：
http://mirrors.ibiblio.org/maven2/ #中有.index目录：nexus-maven-repository-index.gz nexus-maven-repository-index.properties
http://uk.maven.org/maven2/
http://repository.jboss.org/nexus/content/groups/public/
快速的获取nexus-maven-repository-index.gz和nexus-maven-repository-index.properties的方法：先下载这2个文件，再copy到Tomcat ROOT 构建maven2/.index目录(win下尝试在cmd下mkdir)，并修改到80端口。
如果setting.xml中指定的中央仓库为nexus/content/groups/public,在nexus中就应对相应的Public Repositories进行repair index, 如果只对nexus中的Central做repair index,那么eclipse中的maven index不能更新。
index updating:
首先对nexus中setting.xml中指定的中央仓库进行update index,然后对eclipse中的Global Repositories中的中央仓库Rebuild Index即可。

1.在Maven setting.xml文件中配置Nexus仓库,profile mirror ?
本地仓库 >profile > pom中的repository > mirror 但是如果<mirrorOf>*</mirrorOf>，maven会忽略掉其他设置的各种类型仓库，只在mirror里面找。
中央仓库(central,Central Repository), 中央仓库是maven核心自带的远程仓库,默认url在 MAVEN_HOME/lib/maven-model-builder-3.X.jar,
org/apache/maven/model/pom-4.0.0.xml -->
<repositories>
<repository>
<id>central</id>
<name>Central Repository</name>
<url>https://repo.maven.apache.org/maven2</url>
<layout>default</layout>
<snapshots>
<enabled>false</enabled>
</snapshots>
</repository>
</repositories>
<pluginRepositories>
<pluginRepository>
<id>central</id>
<name>Central Repository</name>
<url>https://repo.maven.apache.org/maven2</url>
<layout>default</layout>
<snapshots>
<enabled>false</enabled>
</snapshots>
<releases>
<updatePolicy>never</updatePolicy>
</releases>
</pluginRepository>
</pluginRepositories>
<build>
<directory>${project.basedir}/target</directory>
。。。。。。
e.g:【<dependency>
<groupId>xxx</groupId>
<artifactId>xxx</artifactId>
<version>1.0</version>
<scope>system</scope>
<systemPath>${project.basedir}/lib/xxx.jar</systemPath>
</dependency>】
在setting.xml中：
<mirror>
<id>nexus</id>
<name>Nexus Public Mirror</name>
<url>http://localhost:8081/nexus/content/groups/public</url>
<mirrorOf>central</mirrorOf><!--override the default central repository[https://repo.maven.apache.org/maven2]-->
</mirror>
project's pom.xml中的repositories只是补充central repository而非替代！
2.Hosted upload ? 部署构件到Nexus仓库?
<distributionManagement>
<repository>
<id>releases</id>
<name>Releases</name>
<url>http://192.168.0.21:8081/nexus/content/repositories/releases</url>
</repository>
<snapshotRepository>
<id>snapshots</id>
<name>Snapshots</name>
<url>http://192.168.0.21:8081/nexus/content/repositories/snapshots</url>
</snapshotRepository>
</distributionManagement>
Maven:
M2_HOME
update project--->.lastUpdated
针对私服与中央仓库或第三方仓库之间网络传输问题
Browser Storage--->找到相应的package 先update index,再expire cache
Eclipse:
Maven Preferences-->installations: MAVEN_HOME , User Settings: MAVEN_HOME
pom.xml -->JDK VERSION CFG :
<build>
<finalName>project name</finalName>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.7</source>
<target>1.7</target>
</configuration>
</plugin>
</plugins>
</build>
