I want to create a local repository for maven. For that, I have to download all required artifacts. Is there any direct download link available for all artifacts to be downloaded once?
The local repository will be automatically be created during your first call of Maven in relationship with a project. The default location for the local repository is $HOME/.m2/repository.
You don't need to download dependencies etc. cause Maven will do that automatically.

I would like to install the spring-boot-starter-parent jar and upload it to my private nexus 3 repo. Then I hope to configure my project pom file to retrieve the dependency from there. How can i download spring-boot-starter-parent jar?
My intention is to set up this nexus repo so that future projects will pull depencies from this nexus repo (where this environment is not connected to the internet)
No need to upload in your nexus. You can configure proxy-repository:
A repository that proxies everything you download from Maven Central. Next time you download the same dependency, it will be cached in your Nexus.
Look at this for details
Need to do following configuration:
– create a private (hosted) repository for our snapshots
– create a private (hosted) repository for our releases
– create a proxy repository pointing to Maven Central
– create a group repository to provide all of these repos under a single URL
Another procedure:
If you want to upload list of jar then write gradle task to upload nexus repository. here you get details.
Will the .m2 folder be created automatically by Maven, or do you need to create it manually?
What does the .m2/repository, contain and from where does it come?
First, it will be created by Maven when you execute a build, such as:
mvn clean install
Note, you could find this out just be executing mvn your self ;)
Second, the contents of .m2 are:
A settings.xml file that contains global settings for all maven executions.
A folder called repository that holds all of the local copies of various maven artifacts, either caches of artifacts pulled down from remote repositories, such as Maven Central, or artifacts built by your local maven builds. The artifacts are organized in there in folder structures that mirror the groupId's of the artifacts.
It will be created automatically. The repository folder (also called local repository) will download its content from repositories specified in your user's settings.xml, the global settings.xml and possibly in your poms.
Most artifacts will be downloaded from repo1.maven.org.
I am reading up Maven - The complete reference and came across this
Maven assumes that the parent POM is available from the local repository, or available in the parent directory (../pom.xml) of the current project. If neither location is valid this default behavior may be overridden via the relativePath element.
What exactly is meant by local and remote repository for a Maven installation and a project?
A local repository is a local directory structure that caches artifacts downloaded from remote repositories, or those that are manually installed (eg from the command line option).
A remote repository is a web service (defined by a URL) that contains versioned artifacts. This might be as simple as an Apache server, or a full-blown Maven repository, such as Artifactory, that allows uploading, permissions based on a user directory, etc.
http://maven.apache.org/guides/introduction/introduction-to-repositories.html
By default, Maven will source dependencies from, and install dependencies to, your local .m2 repository. This is a precedence rule, and your .m2 acts like a cache where Maven can source dependencies before downloading them remotely. You can bypass this behaviour like so: mvn -U ... (see mvn --help).
Your local .m2 can be found under C:\Users\{user}\.m2 on Windows, or /home/{user}/.m2 on Linux. If you do a mvn install, your project will be locally installed under the said .m2 repository.
A remote repository is a Maven repository, just like your local .m2 repository, hosted for you to source dependencies from, e.g. Maven Central.
Local repository is a repo. Into your local system, when you compile or install project all required dependencies downloaded into your local repo.
When you're working with your project, then Maven first tries to get dependencies from local. If it's not available, then Maven will try to download the dependency from a central repository.
central repo. is a online repo, which is provided by maven itself.
I have create a maven local depository using "Artifactory". I want to add project dependencies to this local repository(all dependencies in my local .m2 folder), can I do that with Artifactory?. If can, how can I do it?
The dependencies will be added to Artifactory on the first run of your maven project (they will be fetched from one of the remote repositories Artifactory come preconfigured with).
i created a maven repository using nexus and upload the jars files.Same way how to upload the maven plugins to repository.i directly add the maven-complier-plugin,it is not working.it will gives some exception like org.apahce,parenet ,plexus ,codehaus required and org.apache.maven.lifecycle errors are geting..
i will not be maven central repository,only using commpany repository includes every in my repository jars and maven plug
plz help me i am first create the repository.
Did you specify a mirror in your settings.xml file? If you want to force all users to use your repo and not repo1.maven.org, you'll need to enforce that. Also, you probably want your nexus to proxy central so that any artifact you don't host will still be available once you setup the mirror to block all outside repos.
