There is on nexus repository which my application always connects in the building process. I don't find where this repository is set so:
is it possible to set in the pom.xml that do not connect to a specific repository?
settings.xml file is the correct location to configure this.

I've installed a local nexus on my computer to use it as a mirror of the numerous nexus servers that my company have.
I think it's working because if I access the following URL oin my browse:
http://localhost:2312/repository/my_repo/org/apache/maven/plugins/maven-clean-plugin/2.5/maven-clean-plugin-2.5.pom
It's show the content of the .pom file.
But when I run mvn clean install on prompt, I got the following:
Failed to transfer file: http://localhost:2312/repository/my_repo/org/apache/maven/plugins/maven-clean-plugin/2.5/maven-clean-plugin-2.5.pom. Return code is: 504 , ReasonPhrase:Gateway Timeout.
On my maven settings.xml I put this:
<mirrors>
<mirror>
<id>Nexus</id>
<name>Nexus Local</name>
<url>http://localhost:2312/repository/my_repo/</url>
<mirrorOf>*</mirrorOf>
</mirror>
</mirrors>
What am I missing?
Have you setup your settings.xml like this:
<settings>
<mirrors>
<mirror>
<!--This sends everything else to /public -->
<id>nexus</id>
<mirrorOf>*</mirrorOf>
<url>http://localhost:8081/nexus/content/groups/public</url>

In my settings.xml I have configured this -
<mirrors>
<mirror>
<id>lon33881xus</id>
<name>Project Nexus Repo</name>
<url>http://lonrs08358:9093/nexus/content/groups/public</url>

<url>http://m2.neo4j.org/content/repositories/releases/</url>
</mirror> -->
</mirrors>
But still when the maven build runs only the 1st repository is seahced for jars and then the build fails as it is unable to find jars which are present in 2nd repository. I want jars to be searched in 1st repo and if not found then in 2nd. I am new to maven please help.
The best option here is configure your local nexus to use http://m2.neo4j.org/content/repositories/releases. Add this site to nexus as proxy.
Then your configuration should be like this:
<settings>
<mirrors>
<mirror>
<!--This sends everything else to /public -->
<id>nexus</id>
<mirrorOf>*</mirrorOf>
<url>http://lonrs08358:9093/nexus/content/groups/public</url>
</mirror>
</mirrors>
<profiles>
<profile>
<id>nexus</id>
<!--Enable snapshots for the built in central repo to direct -->
<!--all requests to nexus via the mirror -->
<repositories>
<repository>
<id>central</id>
<url>http://central</url>
<releases><enabled>true</enabled></releases>
<snapshots><enabled>true</enabled></snapshots>
</repository>
</repositories>
<pluginRepositories>
<pluginRepository>
<id>central</id>
<url>http://central</url>
<releases><enabled>true</enabled></releases>
<snapshots><enabled>true</enabled></snapshots>
</pluginRepository>
</pluginRepositories>
</profile>
</profiles>
<activeProfiles>
<!--make the profile active all the time -->
<activeProfile>nexus</activeProfile>
</activeProfiles>
</settings>
After that all actions are done behind the scene. When your local nexus does not have library it will download from proxy and then you should receive that library also in your local repo.
I have a project that it has a directory named repo in which artifacts are stored. When I build it with maven, nexus says that the dependencies cannot be resolved; and when I remove nexus from maven settings, it can find the artifacts.
I want maven to look into this directory before asking nexus, or sth like that, so that I can build this without diactivating nexus every time. How can I do that? My current maven settings (~/.m2/settings.xml):
<settings>
<localRepository>/home/a/.m2/repository</localRepository>
<mirrors>
<mirror>
<!--This sends everything else to /public -->
<id>nexus</id>

Nexus website says the mirrorOf pattern of * causes any repository request to be redirected to this mirror and to your single repository group, which in the example is the public group.
It is possible to use other patterns in the mirrorOf field. A possible valuable setting is to use external:*. This matches all repositories except those using localhost or file based repositories.
Putting external:* instead of * solved my problem.
Update:
Second Solution:
Pass this option to maven works fine too:
mvn -Dmaven.repo.local=/path/to/repo
With the maven3 configuration file settings.xml

and a nexus maven proxy (version 2.7.2-03) I have to wait for a bunch of very slow downloads of maven-metadata.xml file every day after 00:00 a.m. (take about 5 mintues together for some KB which ought to be transfered within seconds). How can I prefetch those file in order to download them my local nexus instance?
It sounds like you have one or more proxy repositories that have remotes that are responding very slowly. Once a day the cache timeouts for these expires, resulting in very slow retrieval.
See here for information on how to debug this, and configure Nexus to prevent the issue from occurring again:

Can't compile Spring Roo (1.2.3.RELEASE) project when using Nexus.
mvn says can't find roo.annotations:jar
[ERROR] Failed to execute goal on project Roo123: Could not resolve dependencies for project com.example.roo:Roo123:jar:0.1.0.BUILD-SNAPSHOT: Failure to find org.springframework.roo:org.springframework.roo.annotations:jar:1.2.3.RELEASE in http://192.168.16.232:8081/nexus/content/groups/public was cached in the local repository, resolution will not be reattempted until the update interval of nexus has elapsed or updates are forced -> [Help 1]
However this jar is already in local maven repository.
When disabling Nexus, by renaming .m2\settings.xml, it works fine.
settings.xml has just 1 mirror configured
<mirror>
<id>nexus</id>
<mirrorOf>*</mirrorOf>
<url>http://192.168.16.232:8081/nexus/content/groups/public</url>
</mirror>
How to configure Nexus?
(Adding http://spring-roo-repository.springsource.org/release as proxy repository doesn't help)
UPDATE: add picture. Adding spring-roo-repository on the left side doesn't help.
Two long answeres below doesn't help either.
It's not enough to configuration a mirrorof only you have to configure the following:
<settings>
<mirrors>
<mirror>
<!--This sends everything else to /public -->
<id>nexus</id>
<mirrorOf>*</mirrorOf>
<url>http://localhost:8081/nexus/content/groups/public</url>
</mirror>
</mirrors>
<profiles>
<profile>
<id>nexus</id>
<!--Enable snapshots for the built in central repo to direct -->
<!--all requests to nexus via the mirror -->
<repositories>
<repository>
<id>central</id>
<url>http://central</url>
<releases><enabled>true</enabled></releases>
<snapshots><enabled>true</enabled></snapshots>
</repository>
</repositories>
<pluginRepositories>
<pluginRepository>
<id>central</id>
<url>http://central</url>
<releases><enabled>true</enabled></releases>
<snapshots><enabled>true</enabled></snapshots>
</pluginRepository>
</pluginRepositories>
</profile>
</profiles>
<activeProfiles>
<!--make the profile active all the time -->
<activeProfile>nexus</activeProfile>
</activeProfiles>
</settings>
Apart from your configuration you need to delete your local repository and retry the build. Have you configured Nexus correctly to have access to the internet like maven central etc. ?
I don't know if you have admin access to your Nexus install, but you have to add a new proxy repository to your Nexus install.
The repo you have to add is
http://spring-roo-repository.springsource.org/release
You should have a settings file like below (slightly different than khmarbaise's version):
<settings
xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">

You have to override central (see above), so that Maven won't connect to the default central (repo1.maven.org).
