很慢 Maven

C:\eclipse\workspace>mvn --version

C:\eclipse\workspace>mvn archetype:generate
[INFO] Scanning for projects...
Downloading from central: https://repo.maven.apache.org/maven2/org/apache/maven/plugins/maven-install-plugin/2.4/maven-install-plugin-2.4.pom
Progress (1): 6.4 kB

Maven is very slow on my computer. I executed mvn archetype:generate and it's sitting at this point for 15 minutes. My inte.net connection is fast. I can download a large library from the inte.net in short time.

Can anyone suggest a solution?

Answer 1

Since maven does not work well at slow internet connection, local proxy and cache maybe good idea.

Repocache is remarkable.

Add repocache.cfg

[mvn.upstream.apache]
url = https://repo.maven.apache.org/maven2
This will cache package at mvn/releases.

Change $HOME/.m2/settings.xml add:

<repository>
  <id>apache</id>
  <url>http://127.0.0.1:5000/mvn/apache</url>
</repository>

This worked for me.

Answer 2

The problem may be a lost.network disk connection. I had a similar issue. And after dropping the not available.network disk, it started to work normally. More about this Slow maven unit tests
