How to set order of repositories in Maven settings.xml

Question

I have 3 repositories in my settings.xml because I need artifacts from all of them. Whenever a dependency is not found, Maven tries

Downloading: http://some.server/mvn2repo/releases/org/apache/lucene/lucene-core/2.9.1/...
[INFO] Unable to find resource 'org.apache.lucene:lucene-core:pom:2.9.1' in repository
Downloading: http://some.server/mvn2repo/3rdParty/org/apache/lucene/lucene-core/2.9.1/...
[INFO] Unable to find resource 'org.apache.lucene:lucene-core:pom:2.9.1' in repository
Downloading: http://repo1.maven.org/maven2/org/apache/lucene/lucene-core/2.9.1/lucene-core-2.9.1.pom
<success>

all repositories, but most of the time finds the artifact in central (repo1) of course. I want Maven to check this repo first. I tried order of declarations in settings.xml, but did not work. According to fgysin I also tried the reverse order, which didn't change anything.

My Maven version:

C:\>mvn -v
Apache Maven 2.2.1 (r801777; 2009-08-06 21:16:01+0200)
Java version: 1.6.0_15

Default locale: de_AT, platform encoding: Cp1252
OS name: "windows vista" version: "6.0" arch: "amd64" Family: "windows"

My settings.xml

None of these answers were correct in my case.. the order seems dependent on the alphabetical ordering of the <id> tag, which is an arbitrary string. Hence this forced repo search order:

            <repository>
                <id>1_maven.apache.org</id>
                <releases>  <enabled>true</enabled>  </releases>
                <snapshots> <enabled>true</enabled> </snapshots>
                <url>https://repo.maven.apache.org/maven2</url>
                <layout>default</layout>
            </repository>

            <repository>
                <id>2_maven.oracle.com</id>
                <releases>  <enabled>true</enabled>  </releases>
                <snapshots> <enabled>false</enabled> </snapshots>
                <url>https://maven.oracle.com</url>
                <layout>default</layout>
            </repository>

It must have been some specific (bugged?) range of maven versions. I have maven 3.6 and it's the order as lined out in the accepted answer. — sjngm, Apr 16 '19 at 17:30
yeah I think that bug was this one: https://issues.apache.org/jira/browse/MNG-4400 after Maven 3.0 it reads in the proper order declared — Rhubarb, Jun 01 '20 at 10:07

As far as I know, the order of the repositories in your pom.xml will also decide the order of the repository access.

As for configuring repositories in settings.xml, I've read that the order of repositories is interestingly enough the inverse order of how the repositories will be accessed.

Here a post where someone explains this curiosity:

Your link looks promising and I tried reversing the order, but it doesn't help. – Peter Kofler Mar 16 '11 at 17:11

Hmm, strange. What version of Maven are you using? – fgysin Mar 17 '11 at 09:01

Indeed, on a fresh project the order is 1) active profiles desc (reversed) AND then 2) repositories asc. So "central" should be the first repo in the last activated profile. – Peter Kofler May 07 '11 at 22:50

It is not the inverse order. You should specify the local repo to be the first one in your tag – vsingh Feb 12 '15 at 19:10

Also, consider to use a repository manager such as Nexus and configure all your repositories there.

Why you can't use it? If that's because you can't maintain your own server, you can give a try to [Artifactory Online](https://www.jfrog.com/home/v_artifactorycloud_overview), you'll get a cloud Maven repo up and running in minutes. – JBaruch Aug 06 '13 at 06:24
