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>
<id>vaadin-snapshots</id>
<url>http://oss.sonatype.org/content/repositories/vaadin-snapshots/</url>
<releases>
<enabled>false</enabled>
</releases>
<snapshots>
<enabled>true</enabled>
</snapshots>
</repository>
</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.

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 .
In my Maven configuration I have 6 repositories. 3 Open Source for Geo Tools Java framework and 3 proprietary with encrypted credential access.
<repository>
<id>maven2-repository.dev.java.net</id>
<name>Java.net repository</name>
<url>http://download.java.net/maven/2</url>
</repository>
<repository>
<id>osgeo</id>
<name>Open Source Geospatial Foundation Repository</name>
<url>http://download.osgeo.org/webdav/geotools/</url>
</repository>
<repository>
<snapshots>
<enabled>true</enabled>
</snapshots>
<id>boundless</id>
<name>Boundless Maven Repository</name>
<url>http://repo.boundlessgeo.com/main</url>
</repository>
I added the external repositories mentioned here: http://docs.geotools.org/latest/userguide/tutorial/quickstart/eclipse.html
I added the plugin repositories as well and updated my settings.xml so the repositories in both matched.
<pluginRepository>
<id>maven2-repository.dev.java.net</id>
<name>Java.net repository</name>
<url>http://download.java.net/maven/2</url>
</pluginRepository>
<pluginRepository>
<id>osgeo</id>
<name>Open Source Geospatial Foundation Repository</name>
<url>http://download.osgeo.org/webdav/geotools/</url>
</pluginRepository>
<pluginRepository>
<snapshots>
<enabled>true</enabled>
</snapshots>
<id>boundless</id>
<name>Boundless Maven Repository</name>
<url>http://repo.boundlessgeo.com/main</url>
</pluginRepository>
I even downloaded the jars I need for these Geo Tool dependencies and placed them in my .m2 folder.
<dependency>
<groupId>org.geotools</groupId>
<artifactId>gt-shapefile</artifactId>
<version>18.2</version>
</dependency>
<dependency>
<groupId>org.geotools</groupId>
<artifactId>gt-epsg-hsql</artifactId>
<version>18.2</version>
</dependency>
However, when I try and run a mvn clean install -X I can see that I am getting a 401 Unauthorized when Maven is trying to transfer org.geotools jars to/from the proprietary repositories I have configured, but I don't even want Maven to try.
How can I configure Maven so that for org.geotools.* load from these 3 repositories : <id>maven2-repository.dev.java.net</id>, <id>osgeo</id>, <id>boundless</id> and otherwise load from the proprietary repositories?
I heard that I can configure a proxy, but nobody is explaining how I would do that. I tried to store the jars I need for Geo Tools in my proprietary repository, but was told I can't. I also tried to configure a mirror to direct traffic to those external repositories only in my settings.xml like this below, but am seeing issues of cannot transfer jars from/to that only exist in the proprietary repository.
<mirrors>
<mirror>
<id>boundless</id>
<name>Boundless Repository Mirror</name>
<url>http://repo.boundlessgeo.com/main</url>
<mirrorOf>*</mirrorOf>
</mirror>
</mirrors>
I don't know if this can be done with maven but can be done with Artifactory virtual repositories. Other repository management tools should have similar concepts.
Basically you setup a Artifactory repository and your applications should refer to this repository. And you can configure inside Artifactory to which jars should be download from which repositories.
Consider that the Include Patterns and Exclude Patterns for a repository are as follows:
Include Patterns: org/apache/,com/acme/
Exclude Patterns: com/acme/exp-project/**
In this case, Artifactory will search the repository for org/apache/maven/parent/1/1.pom and com/acme/project-x/core/1.0/nit-1.0.jar but not for com/acme/exp-project/core/1.1/san-1.1.jar because com/acme/exp-project/** is specified as an Exclude pattern.

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 add to my project some special dependeny from some repository.
For this I add the repository in my pom:
<repositories>
<repository>
<id>jenkins-repo</id>
<name>Jenkins Repository</name>
<url>maven.jenkins-ci.org/content/repositories/releases</url>
<releases>
<enabled>true</enabled>
</releases>
<snapshots>
<enabled>true</enabled>
</snapshots>
</repository>
</repositories>
.. and in the same file add the dependency:
<dependency>
<groupId>org.jvnet.com4j</groupId>
<artifactId>com4j</artifactId>
<version>20120426-2</version>
</dependency>
But it doesn't work: the dependency is not found. As far as I understand this proves that the dependency exists in the right place:
http://maven.jenkins-ci.org/content/repositories/releases/org/jvnet/com4j/com4j/20120426-2/
So here are the questions:
1) Where I went wrong?
2) If I add repository to pom the default repository still be checked?
3) The link provided is really a link to Maven repo which proves I can download an artifact from it?
change <url> to include protocol
<url>http://maven.jenkins-ci.org/content/repositories/releases</url>
How do I enable access to the Apache commons snapshots from my maven settings configuration file.
add to your pom.xml:
<repositories>
<repository>
<id>repository.apache.org.snapshots</id>
<name>Apache snapshots repo</name>
<url>https://repository.apache.org/content/groups/snapshots/</url>
<snapshots>
<enabled>true</enabled>
</snapshots>
</repository>
</repositories>
In your question, you ask about "settings" but it's a bad idea to declare this repo. in your settings.xml.
Take a look at the repositories section of the Maven settings reference.
