[Building Sakai] When (if) plugin repositories go down..

[Balazuc Denis]

Hi Branden and everyone

This can happen when remote repositories are down for maintenance or other connectivity reasons.
To avoid this and make sure you can do a full build cycle for your project regardless, a common solution is to setup a Maven proxy.
http://maven.apache.org/guides/mini/guide-proxies.html

This usually requires that you install a server within your organisation to act as the proxy. There are some good products out there that do that well, such as Nexus (http://nexus.sonatype.org/). 

On top of not depending on external repositories' availability, the added benefit to having a Maven proxy is that it makes downloading components much faster, as well as providing the ability to maintain and share your own maven artifacts within your organisation.


Hope this helps.

Subject: [Building Sakai] When (if) plugin repositories go down..

Hi everyone,
  
  Yesterday morning I was trying to deploy some patches to our servers, 
  and the deploy ended up hanging on this line:
  
  [INFO] artifact org.apache.maven.plugins:maven-one-plugin: checking for 
  updates from codehaus snapshot repository
  
  I let it hang for about 3 minutes before I killed the process.
  
  My first instinct (a shot in the dark) was to disable snapshots for that 
  plugin repo, not sure if it should have solved the problem. After I did 
  this, the Maven build worked but it still output that line. So I'm 
  thinking the codehaus could have just come back up by coincidence?
  
  To avoid any future problems, does anyone know what could have happened 
  here, and how to run completely local if I get stuck in a jam with bad 
  repos?
  
  Thanks,
  
  Branden
