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:

配置 oschina的mirror:

<mirrors>
...
        <mirror>
            <id>osc</id>
            <mirrorOf>central</mirrorOf>
            <url>http://maven.oschina.net/content/groups/public/</url>
        </mirror>
        <mirror>
            <id>osc_thirdparty</id>
            <mirrorOf>thirdparty</mirrorOf>
            <url>http://maven.oschina.net/content/repositories/thirdparty/</url>
        </mirror>
...
</mirrors>

配置阿里云的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>

配置 profile

<profiles>
...
        <profile>
            <id>osc</id>
            <activation>
                <activeByDefault>true</activeByDefault>
            </activation>
            <repositories>
                <repository>
                    <id>osc</id>
                    <url>http://maven.oschina.net/content/groups/public/</url>
                </repository>
                <repository>
                    <id>osc_thirdparty</id>
                    <url>http://maven.oschina.net/content/repositories/thirdparty/</url>
                </repository>
            </repositories>
            <pluginRepositories>
                <pluginRepository>
                    <id>osc</id>
                    <url>http://maven.oschina.net/content/groups/public/</url>
                </pluginRepository>
            </pluginRepositories>
        </profile>
...
</profiles>

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。

完毕。
