maven-2 - 为什么我的 Maven 在 Ubuntu 上这么慢？

Question

我在 Ubuntu 服务器上有 Maven。

似乎尝试了很多很多的地方来下载，但是下载超时了，但是超时需要很长时间，所以我的整个构建花了一个多小时。

我的 Maven 构建中只设置了两个存储库

<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

看来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。另请检查您正在使用的用户的文件~/.m2/settings.xml。

PS:我不太喜欢将 .deb 用于此类软件，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_HOME 环境变量并将 $M2_HOME/bin 添加到 $PATH)。
