为什么我的Maven在Ubuntu上这么慢？

Question

我在Ubuntu服务器上有Maven.

它似乎尝试了很多很多地方可供下载,但是下载超时,但是超时需要很长时间,因此我的整个构建需要一个多小时.

我的maven构建中只有两个repos set

<repository>
    <id>central</id>
    <name>Maven Repository Switchboard</name>
    <layout>default</layout>
    <url>http://repo1.maven.org/maven2</url>
    <snapshots>
        <enabled>false</enabled>
    </snapshots>
</repository>

<repository>
  <id>maven2-repository.dev.java.net</id>
  <name>Java.net Repository for Maven</name>
  <url>http://download.java.net/maven/2</url>
</repository>
<repository>
    <id>repository.jboss.org</id>
    <name>JBoss Repository</name>
    <url>http://repository.jboss.org/maven2</url>
</repository>

谢谢,菲利普

似乎Ubuntu的打包Maven版本附带了一个/etc/maven2/settings.xml.查看此文件以查看它是否包含其他存储库.另请检查~/.m2/settings.xml您正在使用的用户的文件.

PS:我真的不喜欢将.deb用于这种软件,并建议"手动"安装它(即只需下载存档,将其解压缩到某处,设置M2_HOMEenv变量并添加$M2_HOME/bin到其中$PATH).
