I'm currently changing a docker image. The docker image creates a server that allows running some experiments. To adapt its functionality for my purpose, I have to change a class that is contained in a dependency jar file. In the pom.xml file, such jar dependency is downloaded with its dependencies from a nexus repository. I presume that a possible solution is to create a repository in the nexus repository (localhost) and then upload the jar file with its dependencies, right? Anyway, I would have no idea how I can do it. Below is the code concerning it.
Could someone help me up, please?

Yeah you're on the right track. What you're asking about is called a "deploy" in maven. So to deploy your jar generally you'll need to:
Create your nexus instance
Add your new repository to your pom file
Add the maven-deploy-plugin to your pom
Make your code changes
Deploy your jar with the mvn deploy command
Two good resources for lots of details on the steps and the exact content to add to your pom.

I have a local Java intelli-J project with a pom.xml that has (2) internal repositories on artifactory. The problem is I am doing some testing, and I think one of the JARs is not on this internal repo, so I want to use the regular Maven central repo. I googled and believe, the artifact should go through the list in your pom.xml is the order its listed and try to resolve the artifact, the problem is, even when I add the Maven central repo, it seems to never attempt; only tries the internal artifactory then fails.
In my pom.xml:
<repositories>
<repository>
<id>test</id>
<name>Maven Central</name>
<layout>default</layout>
<url>https://repo1.maven.org/maven2</url>
<snapshots>
<enabled>false</enabled>
</snapshots>
</repository>
<repository>
<snapshots>
<enabled>false</enabled>
</snapshots>
<id>my_repo</id>
<name>MyRepo</name>
<url>https://myinternalrepo.com</url>
</repository>
<repository>
<snapshots />
<id>MySnapShotRepo</id>
<name>MyInternalRepo</name>
<url>https://myinternalreposnapshots.com</url>
</repository>
</repositories>
am I doing something wrong here?
I removed my settings.xml and was able to control the repositories from the pom.xml file tag. It also looks like maven repo is automatically tried whether you list it or not in pom .
Is it possible to add remote repository jar file (https://repo.ah/lib/abc.jar) in maven pom.xml as dependency in java project. if so, can you please share example.
No, it's not possible to add a complete repository as a dependency. This doesn't make sense, because a repository can contain ten thousands of artifacts.
If your project requires artifacts which are not hosted in the standard remote repository, you can specify this via the <repositories> tag in your pom.xml .
<repositories>
<repository>
<id>vaadin-addons</id>
<url>http://maven.vaadin.com/vaadin-addons</url>
</repository>
<repository>

Introduction to Repositories
Setting up Multiple Repositories
In the comments you mentioned that the URL is an Artifactory.
So just add the Artifactory as <repository> to your settings.xml and then you can use the jar in your application.
So my default maven settings.xml file in my ~/.m2/ folder is containing links to my work repositories. So whenever I run an install on my pom.xml's it try to fetch from the corp nexus maven repositories.
For a hobby project which I am just starting with I don't want to make use of the corp maven nexus, but to make use of the central maven repo. I don't want to replace the entire settings.xml as this would mean reloading the entire local maven repo once I switch back to my corp work.
How can I achieve this ?
Add the following as your first repository in the repositories tag in the settings.xml
<repository>
<releases>
<enabled>true</enabled>
</releases>
<snapshots>
<enabled>true</enabled>
</snapshots>
<id>central</id>
<url>http://repo1.maven.org/maven2</url>
</repository>
You may also want to use profiles. But, that is not a requirement.
You can also add a repository on your pom
<repositories>
<repository>
<id>central</id>
<url>http://rep1.maven.org/maven2</url>
</repository>
</repositories>
I want to use Sikulix in my maven project but it doesn't work, I tried to add the repository like it says (http://sikulix-2014.readthedocs.org/en/latest/faq/030-java-dev.html#a-comment-on-projects-using-maven) and when I do "mvn install" it says "Could not find artifact com.sikulix:sikulixapi:jar:1.1.0-SNAPSHOT in nexus" where nexus is our repository.
My pom contains that:
...
<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>
</repositories>
<dependencies>
<dependency>
<groupId>com.sikulix</groupId>
<artifactId>sikulixapi</artifactId>
<version>1.1.0-SNAPSHOT</version>
</dependency>
</dependencies>

Any idea why maven does not find the artifact in the correct repo?
The problem is solved. In the settings.xml we had a so maven always used the same repo.
I just removed the mirror because we didn't use it anymore, but I think that adding the additional repository there it would work too.
The problem is that I'm trying to make somelike the helloworld with Activiti but I have an error here
<dependency>
<groupId>org.activiti</groupId>
<artifactId>activiti-engine</artifactId>
<version>5.1</version>
</dependency>
<dependency>
<groupId>org.activiti</groupId>
<artifactId>activiti-spring</artifactId>
<version>5.1</version>
</dependency>
the error is the following: 'Description Resource Path Location Type
Missing artifact org.activiti:activiti-engine:jar:5.1 pom.xml /IllMakeThisTestApp line 29 Maven Dependency Problem
Trying to resolve it I've found the following recomendation here: "The download contains all the libraries that you need to work with Activiti. But for developers that prefer to use Maven, add the following reposiory"
<repositories>
<repository>
<id>Alfresco Maven Repository</id>
<url>https://maven.alfresco.com/nexus/content/groups/public/</url>
</repository>
</repositories>
But where shall I place it? To the file called settings.ini placed in M2_HOME/conf? This file is full of comments with no any sign of repositories. So I have no idea how to do this and ask you for help
You should place that in your pom.xml - see the Maven reference on the subject:
<project xmlns="http://maven.apache.org/POM/4.0.0"...
...
<repositories>
<repository>
<id>Alfresco Maven Repository</id>
...
You will only need to tinker with the Maven config if you need to setup a mirror for the repo, eg. in case your organisation has it's own Nexus/other repo mirroring the outside "world".
Cheers,
You can place right under project. For example
<project>
....
<repositories>
<repository>
<id>spring-snapshots</id>
<url>http://repo.spring.io/libs-snapshot</url>
<snapshots>
<enabled>true</enabled>
</snapshots>
</repository>
</repositories>
</project>
In default maven will try to download all the artifacts from maven central. You can add any number of added repositories using tag given above. Alfresco is yet another open maven repository.
