Hello,

I would like to ask if it is possible to have multiple local maven 
repositories and if it can be set as a parameter in a maven profile.

Multiple Local Repositories

[iamanandkris]

Hi 

Can we have more than one local maven repositories in a computer? So that I
can use one repo for on of my projects and other for other projects?

If so can some one pls give some guide lines on how to facilitate that?

Thank you
Anand

Can you explain what you exactly mean.

Do you mean having a different local caches for different purposes ?

Runinng one build with cache at $HOME/.m2/repository and running a 
second build with cache at $HOME/.m2/repository-run-two


The location of the local cache can be configured via the 
[settings.xml][1] file like this:


http://maven.apache.org/SETTINGS/1.0.0";
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
  xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
  https://maven.apache.org/xsd/settings-1.0.0.xsd";>
  ${user.home}/.m2/repository

This snippet above shows the default...to change it for your own 
purposes you need to change localRepositoy entry...


But usually i can't recommend that, only if you exactyl what you are 
doing...

Hello,

 you can configure local repositories with file: URLs configured in profiles.

https://maven.apache.org/guides/mini/guide-multiple-repositories.html

It is not possible to have the local repository cache in a profile, but you can 
use different settings.xml files with the -s option.

https://maven.apache.org/ref/3.3.9/maven-settings/settings.html

I typically use this to have an opensource/public- and company setting- with 
different mirrors, servers, repositories and a clean repository cache.

Re: Multiple local repositories

Yes. Exactly but is it possible to pass a variable from 
 tag during the build in order to have different 
local caches?

No..the localRepository can not be part of a profile.


But you can use the following:


mvn -Dmaven.repo.local=$HOME/.my/other/repository

Use a different settings file. and configure the right dir in each one:

Re: Multiple Local Repositories

[Ansgar Konermann]

During "normal" use of maven, one repository should be shared between your
projects.

Why do you feel the need to have separate repositories for each of your
projects?

Re: Multiple Local Repositories

[hanasaki]

Generally good to just have one local repo per user.  This defaults to
~/.m2/repository

Based on the pom.xml all the needed dependencies will be pulled from the
remote repos automatically so : no worries.

If you really want more than one local repo for the same user id, take a
look at settings.xml:
http://maven.apache.org/run-maven/index.html#Quick_Start
http://maven.apache.org/guides/mini/guide-configuring-maven.html

In continuous integration - it may be good to have one local repository
per project and a script that deletes the local repository before a
nightly build is performed; else if someone changes the coordinates of a
project, cruft can result in build issues that are hard to track down.

Use of Multiple Local Repositories

[Mehdi Hayani]

Hello,

I'm actually working on a continuous integration platform, and most of the
projects are using Maven as a build tool.

We've found that there is a list of dependencies and plugins most of the
projects have to download in addition of there specific dependencies.
Therefore, I though it could be great if we can use multiple local reposiry
for a build, the idea is:

   - Local repo 1 : Is the shared folder where we will put dependencies
   that are download by each project.
   - Local repo 2 : this one is created for each project and it will
   contains dependencies that are specific to that project.


So while running the build, maven will check in "local repo 1", if it can't
find the required librairy it will download it and put it in "local repo 2"


It there a way to implement this solution :) ?

Thanks in advance

Hi Mehdi,

> it could be great if we can use multiple local reposiry for a build

That has been discussed before on the list [1]. It was an interesting
discussion but ultimately Maven does not support such a feature. I think it
would be useful if a motivated party pursued it, though.

Curtis

Then declare local repo 1 as a remove Maven repo accessed from the file:
URL prefix

Re: Use of Multiple Local Repositories

[Mehdi Hayani]

Thank u for your answer.

@Jeff, if we declare "local repo 1" as a remote Maven repo, During the
build, Maven will copy dependencies from "local repo 1" to "local repo
2", and one of the reasons of trying to set up two local repos at the same
time is to avoid dependencies duplication between projects and therefore
decrease disk space usage.

local repo 2 will contain only what is necessary for the project.

You can take a look at https://github.com/takari/tesla-split-localrepo
I remember seeing a demo of this, but I don't know if it is working with 
recent versions of Maven / Aether
