maven国内源及常见问题。
错误描述
有时候maven编译或者打包时下载包的阶段出错，一般都是网络问题。如：
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.18.1:test (default-test) on project myusml: Execution default-test of goal org.apache.maven.plugins:maven-surefire-plugin:2.18.1:test failed: Plugin org.apache.maven.plugins:maven-surefire-plugin:2.18.1 or one of its dependencies could not be resolved: Failed to collect dependencies at org.apache.maven.plugins:maven-surefire-plugin:jar:2.18.1 -> org.apache.maven.surefire:maven-surefire-common:jar:2.18.1: Failed to read artifact descriptor for org.apache.maven.surefire:maven-surefire-common:jar:2.18.1: Could not transfer artifact org.apache.maven.surefire:maven-surefire-common:pom:2.18.1 from/to central (https://repo.maven.apache.org/maven2): Remote host closed connection during handshake: SSL peer shut down incorrectly -> [Help 1]
解决方式（采用配置国内源）
国内访问某些外国网站的网络很不稳定，因此需要添加国内的中央库，修改$M2_HOME/conf/setting.xml中添加国内的源：
oschina
-
配置的mirror
...
osc
central
http://maven.oschina.net/content/groups/public/
osc_thirdparty
thirdparty
http://maven.oschina.net/content/repositories/thirdparty/
...
-
配置 profile
...
osc
true
osc
http://maven.oschina.net/content/groups/public/
osc_thirdparty
http://maven.oschina.net/content/repositories/thirdparty/
osc
http://maven.oschina.net/content/groups/public/
...
详见http://maven.oschina.net/help.html
aliyun
配置阿里云的源：http://maven.aliyun.com/nexus/#view-repositories;public~browsestorage
- 在maven的settings.xml 文件里配置mirrors的子节点，添加如下mirror
<mirrors>
<mirror>
<id>alimaven</id>
<name>aliyun maven</name>
<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
<mirrorOf>central</mirrorOf>
</mirror>
</mirrors>
// 或
<mirror>
<id>nexus-aliyun</id>
<mirrorOf>*</mirrorOf>
<name>Nexus aliyun</name>
<url>http://maven.aliyun.com/nexus/content/groups/public</url>
</mirror>
FaQ
缓存问题
配置eclipse使用本地安装的maven，而不是自带的版本。同时在User setting里面，也要指定setting.xml是使用哪个配置文件，从而指定国内的库。 否则国内有时候连不上maven中央库，导致出现以下异常：

如果还不行，先到命令行执行mvn clean package，看原因是什么，很有可能是连接中央库失败。
