Backup Maven dependencies to repository - maven

I am frequently using maven artifacts as dependencies from external repositories which go (permanently) offline surprisingly often. I'd like to save all dependencies a given project has and save them in a local repository - just like using maven deploy -DaltDeploymentRepository=... for a single project. This repository should then be usable like any other maven repo when put on an HTTP server.
I tried using mvn dependency:copy-dependencies -Dmdep.useRepositoryLayout=true, but it does not create files like maven-metadata.xml or copy .pom files.
I do not want to use any repository managers like Artifactory, I just have a static file server.
Thanks in advance.

How to download selective dependencies using Maven from JFrog Artifactory?

I have a simple Maven project and its pom.xml has some dependencies to some local jar files inside the project structure. Now I want to upload those local jar files in JFrog Artifactory and change the pom in such a way so as to use selective dependencies from Artifactory and rest of the Pom files remains the same like it was(which includes some spring boot, Junit, surefire dependencies etc etc). How can I alter the pom file so that I can selectively download those jars from Artifactory rather than from my local machine.
I uploaded the local jars in a folder in Artifactory but unable to configure my pom/maven to download those during clean install. I tried as per the documentation in Jfrog to modify the settings.xml and include the server tag and aslo added distribution management in pom.xl to refer to the Jfrog Artifactory. But this is for all the dependencies no? I want selective dependencies to be downloaded from Artifactory.

Download files from nexus repository

How to download files from nexus server ? (Is it for only Maven plugins repository or We can store any dependencies of my project)
You can use maven plugin :
mvn org.apache.maven.plugins:maven-dependency-plugin:2.6:get -DreadmoteRepositories=http://nexus.mydomain.com/nexus/content/repositories/snapshots -Dartifact=com.mydomain.myproject:myproject:1.0.0-SNAPSHOT:jar -Ddest=myfile.jar
OR, you can use REST API if you want : https://maven.java.net/nexus-core-documentation-plugin/core/docs/rest.artifact.maven.redirect.html
nexus per artifact has multiple files (metadata, pom.xml, source, javadoc, jar, etc..), you can download them and use separately in your own project, but that doesn't sounds like very good idea when you have maven todo this for you in managed way

How to install a Maven/Gradle project along with all its dependencies to a local repository?

I have a Gradle project that depends on several open-source projects up on Maven Central. I'd like to install the project – along with all its direct and transitive dependencies – to my local maven repository, so that I could later zip it all up and put it on offline machines.
How do I do it with Gradle/Maven?
mvn dependency:get plugin will fetch the artifact with all dependencies to the local repository.
I had also developed a plugin to install remote artifacts to a local machine.
If you want to later ZIP up your project w/ dependencies and move them to a different machine, you could try Maven's appassembler plugin. It collects all dependencies and creates a launcher, all in the target folder, ready for deployment.
But note, this, by default, creates a flat directory structure with all dependencies, it doesn't preserve the Maven format. It also has the option to create a repository.

Maven private internal repository

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).

maven artifacts for local repository

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.
