为什么我的Maven在Ubuntu上这么慢? [英] Why is my Maven so slow on Ubuntu?

问题描述

我在Ubuntu服务器上有Maven.

I have Maven on Ubuntu server.

似乎尝试了很多地方进行下载，但是下载超时，但是超时会花费很多时间，因此我的整个构建过程要花费一个多小时.

It seems to try lots and lots of places to download from but the download times out, but the timeout takes ages, so my whole build takes more than a hour.

我的Maven构建中只设置了两个存储库

I only have two repos set in my maven build

<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

推荐答案

似乎Ubuntu的打包Maven版本附带了/etc/maven2/settings.xml.查看此文件以查看其是否包含其他存储库.还要检查您正在使用的用户的文件~/.m2/settings.xml.

It seems that Ubuntu's packaged Maven version comes with a /etc/maven2/settings.xml. Have a look at this file to see if it contains additional repositories. Also check the file ~/.m2/settings.xml of the user you are using.

PS:我不太喜欢将.deb用于此类软件，建议您手动"安装它(即，只需下载存档，将其解压缩到某个位置，设置M2_HOME env变量，然后将$M2_HOME/bin添加到$PATH).

PS: I don't really like using .deb for this kind of software and recommend installing it "manually" (i.e. just download the archive, unzip it somewhere, set the M2_HOME env variable and add $M2_HOME/bin to the $PATH).
