How to define a repository in Maven pom.xml - java

How can we define a repository in the pom.xml?
For example if dependency is not found in the repository defined in settings.xml then search for the dependency in the repository defined in pom.xml.
An example on how this can be achieved would be great.
I am aware that placing repositories in the pom.xml is not a good option, but circumstances are pushing for this.


<repositories>
<repository>
<id>java.net</id>
<url>https://maven.java.net/content/repositories/public/</url>
</repository>
</repositories>


From the documentation (example reproduced as is here):
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

Maven plugin dependencies couldn't resolve dependency from internal repo

I am creating parent-pom. There we are defining build->plugin->dependencies.
It can fetch dependencies from maven but it couldn't fetch dependencies from our internal Maven repository. getting below error
[ERROR] Failed to execute goal

Is there anything I missed? Only build plugin dependencies are not resolved where as project dependencies are getting resolved from our internal repository.

It is the default behavior of maven.
When defining <repository> .... </repository> make sure to override the <id>central</id> with your internal repository. If you don't do so, maven will still contact maven central to resolve dependencies and not work without proper proxy settings if you are behind a VPN. The below listing will fetch all your deps from your internal repository.
<repositories>
<repository>
<id>central</id>
<name>Internal Release Repository</name>
<url>https://archiva.global.com/repository/internal</url>

Error in downloading dependency from 2 mirrors in Maven

I want to download spring-native dependency from maven mirror as it is not in my third party mirror.I tried to do it by including maven mirror in my settings.xml file,but it doesn't work.
Settings.xml file-
<?xml version="1.0" encoding="UTF-8"?>

</activeProfiles>
</settings>
I added this dependency-
<dependency>
<groupId>org.springframework.experimental</groupId>
<artifactId>spring-native</artifactId>
<version>0.9.2</version>
</dependency>
Issue-
Cannot resolve org.springframework.experimental:spring-native:0.9.2
How can I resolve this?

When you use <mirrorof>*<mirrorof> then you essentially override all other mirrors and repository definitions. To exclude repositories from the mirror, use
*,!otherrepo

Maven activeProfiles are ignored?

I use for Eclipse a maven settings.xml that has a 3rd-party Artifactory location from which Maven artefacts are retrieved.
We added now an own Artifactory which hosts artefacts not contained in the former Artifactory.
We added new profiles to the settings.xml and activated them.
What happens now, if artefacts shall be retrieved that are only in the new one, the maven build fails with an artefact not found exception.
Looking through the debug-output it seems like Maven never tries to access the new location.
As test, we deactivated the profiles of the 3rd-party Artifactory. Now the debug-log shows that Maven tries to access our Artifactory (but only if there are no other locations than ours).
Has someone an idea why the new Artifactory is ignored if the other profiles are active?
Below is my settings.xml, the upper two "ltl-*" profiles are the new ones which seems to be not used.

I have uploaded these missing jars into Nexus repository into third-party repository.
wguuidJava jar and pom file in my local repository
Could you please let me know if I am missing any configuration in the settings.xml file?

Everything is fine. You have a WARNING, not an ERROR.
This warning is related to how the jar was built and uploaded to the repository. It does not affect functionality.
I hope this helps.

Two maven dependencies from different repos

How can i use selenium and sikuli in one pom.xml ?
<dependency>
<groupId>org.seleniumhq.selenium</groupId>
<artifactId>selenium-java</artifactId>
<version>2.45.0</version>
</dependency>
<dependency>
<groupId>com.sikulix</groupId>
<artifactId>sikulixapi</artifactId>
<version>1.1.0-SNAPSHOT</version>
</dependency>
sikuli is in :
<repository>
<id>com.sikulix</id>
<name>com.sikulix</name>
<url>https://oss.sonatype.org/content/groups/public</url>
<layout>default</layout>
<snapshots>
<enabled>true</enabled>
<updatePolicy>always</updatePolicy>
</snapshots>
</repository>
but adding this repo, makes maven to look there for selenium too
is it possible to link two different dependencies from two different repositories ?

Maven looks for artifacts (selenium, sikulixapi, ..) in all defined repositories.
You can define two: com.sikulix and the standard one:
<repositories>
<repository>
<id>com.sikulix</id>
<name>com.sikulix</name>
<url>https://oss.sonatype.org/content/groups/public</url>
<layout>default</layout>
<snapshots>
<enabled>true</enabled>
<updatePolicy>always</updatePolicy>
</snapshots>
</repository>
<repository>
<id>central</id>
<name>Maven Repository Switchboard</name>
<layout>default</layout>
<url>http://repo1.maven.org/maven2</url>
<snapshots>
<enabled>false</enabled>
</snapshots>
</repository>
