All
Need to get maven to copy central dependencies to local filesystem repository mirror. Can't work out how to do this in maven (3.3.1).
We have:
[1] maven central, which for the UK is: "http://uk.maven.org/maven2"
[2] local remote filesystem repository mirror: "c:/mylocalRepository"
[3] local repo "c:/users/myuser/.m2/repository"
Version of maven is 3.3.1 (doing a migration from 2.0.10).
We need to run our system without connecting to central (behind firewalls) and also without using a repository manager (Nexus, Archiva or the like) - it's something we would like to change but cannot change our infrastructure immediately. Please don't reply just saying do this.
Therefore we need our dependencies in a local file system that maven will then be use as a mirror of central.
I can't find a way to configure maven to build this - I'm getting dependencies - jar + pom and then using
To install jars:
mvn org.apache.maven.plugins:maven-deploy-plugin:2.8.2:deploy-file
-Durl="file:///{repositoryPath}"
-DrepositoryId="InternalRepo"
-Dfile="{jarFile}"
-DpomFile="{pomFile}"
-DrepositoryLayout=default
-DgroupId={groupId}
-DartifactId={artifactId}
-Dversion={version}
-Dpackaging=jar
-s "C:/apache-maven-3.3.1/conf/settings_centralRepo.xml"
To install Poms:
mvn org.apache.maven.plugins:maven-deploy-plugin:2.8.2:deploy-file
-Durl="file:///{repositoryPath}"
-DrepositoryId="InternalRepo"
-Dfile="{pomFile}"
-DpomFile="{pomFile}"
-DrepositoryLayout=default
-DgroupId={groupId}
-DartifactId={artifactId}
-Dversion={version}
-Dpackaging=pom
-s "C:/apache-maven-3.3.1/conf/settings_centralRepo.xml"
Ideally would like a configuration that we could put in the parent pom that would trigger all dependencies to be copied over. However the documentation implies this is for build artifacts rather than dependencies. There's usually a way in maven, but it can be hard to find.
Any help much appreciated - I've currently jury-rigged a script to do this and it tedious and labour intensive.
The maven configuration mentioned in the Usage section of the Natural Docs Maven Plugin site:
<groupId>org.codehaus.mojo.naturaldocs</groupId>
<artifactId>naturaldocs-maven-plugin</artifactId>
<version>1.0-SNAPSHOT</version>
However; I can't seem to find any version in any Maven repository including Maven Central or the Snapshot repo.
I was able to find what seems like the initial version attached to this Mojo plugin submission but it only includes source, and while it's nice to look at I don't wish to compile it for use myself.
Grab the source archive that you referenced and unzip it in a convenient spot.
From that folder, run:
mvn clean install
Assuming that runs without issue, run:
mvn install:install-file -Dpackaging=jar -Dfile=target\naturaldocs-maven-plugin-1.0-SNAPSHOT.jar -DgroupId=org.codehaus.mojo.naturaldocs -DartifactId=naturaldocs-maven-plugin -Dversion=1.0-SNAPSHOT
Assuming that runs fine, check the local deploy works as expected by including the pom reference in your project.
<dependency>
<groupId>org.codehaus.mojo.naturaldocs</groupId>
<artifactId>naturaldocs-maven-plugin</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
If your project build without issue, then deploy it to your local Maven repo by running:
mvn deploy:deploy-file -Dpackaging=jar-Drepository=extNonFree -Durl=scpexe://maven.your-company.com/your-serverpath/maven/proximity/ext-non-free/storage -Dfile=target\naturaldocs-maven-plugin-1.0-SNAPSHOT.jar -DgroupId=org.codehaus.mojo.naturaldocs -DartifactId=naturaldocs-maven-plugin -Dversion=1.0-SNAPSHOT
Or have one of your local Maven admins deploy the pom and jar manually.
I hope that helps.
I have started to work on maven project recently.
The piece of code I am writing needs JAR files that are not a part of the project.
When I add the JARS TO THE build path and use a mvn clean install, the build is failing with errors saying that the classes that were supposed to be in the jar were not found.
Is there anything that i am missing?
Is there a different way to add the JAR's in maven projects?
If the JARs are already hoisted in some public Maven repositories, add them to the <dependency> section in the pom.xml . You may have to configure the address of these public Maven repositories in the <repositories> section in the pom.xml in order to cause Maven can connect them.
Otherwise , you have to use the install command to include these JARs into the your local repository and then add their <dependency> section in the pom.xml
The command to install the JARs into your local repository:
mvn install:install-file -DgroupId=com.abc -DartifactId=XXXXX
-Dversion=1.0 -Dpackaging=jar -Dfile=/path/to/jars
It sounds like you don't understand how Maven works. You don't add jars to the build path, you declare them in the pom, and let Maven download to the local drive, and it adds it to the build path for you. I would recommend you read this 5 minute intro, and understand how the dependency management works.
In grape there is a nice way to download any artifact to repo directly, just calling something like
grape install org.apache.derby derby 10.5.3.0
As far as I understand, maven install:install goal requires pom.xml file, and maven install:install-file requires local file which you are pointing to and which you actually want to place in local repo.
Is there is any way to install any artifact to maven repo directly, without creating maven project and declaring dependency in pom.xml?
UPD: I guess the search is over. We should use dependency:get goal.
I'm new to maven project.
I'm changing an ant project to maven project.
To install the 3rd party jar's in maven local repository, I used install command.
Its trying to download the resource jar.pom.
I don't have download access in my organization so the build failed for installtion.
After request i got the resouce jar and clean jar in my desktop(also i can get other necessary jar).
How to make maven to use these jar for the process and how to install the jar in local repository without internet acess.
I downloaded the jar and placed in local repository but it couldn't point the path and use those jars.
please let me know what steps i have follow to run maven install and other commands to build the project without internet access.
where should i placed the jar which i have downloaded by external way.
Please guide me for building and deploying the project.
Thanks in advance.

I've posted same question in these link
You need an internet connection. Maven isn't initially self-sufficient. It needs to download a bunch of plugins along with their dependencies and the dependencies of your own project. And this really depends on what sort of settings you have for your projects. One set up will require one set of dependencies, another - a whole different one. You can't download artifacts from the Maven Central manually and then install them locally one by one. Simply put, that sounds stupid.
I understand that you're coming from the Ant world where Ant has everything it needs on the local file system. However, Maven relies on the fact that it will have a central repository (either Maven Central, or your own repository - Nexus, Artifactory, etc.) from which to download the plugins and dependencies it needs. There is no point in you migrating to Maven, unless you'll be allowed access to the Central Maven Repository.
Yes, indeed, you can run Maven offline and you can have Maven produce a local repository for you to use when you are in offline mode. However, what you're trying to do is against Maven's principles.
If your company won't allow access to Maven Central, just stick to Ant. Your effort will be a waste of your company's and, ultimately, your own time.
In fact the maven strenght is mainly in the internet accessible repositories and automatic dependency management. But it's possible to use this tool to build your project if you have all dependencies required for your project in your local repository. Then you may use -o option for offline mode and maven will not try to download updated artefact versions.
To get the artifacts into you local repository you have several options:
1) connect to the internet once and mvn build the project (this will download all required dependencies)
2) install dependencies as jar to the local repository manualy (using appropriate mvn command)
I think the questioner is looking for -o or --offline option for mvn. This is a command line option and can be provided while executing.
I think you can setup your repo correctly and execute the mvn goals once when you are connected to internet and use the -o option for later executions .
Hope this helps.

You can configure maven to run in offline mode. Add this entry to your settings.xml
<offline>true</offline>
See here for further information:
http://maven.apache.org/settings.html
Before you can use offline mode, you have to install all necessary third party jars to your local maven repository.
mvn install:install-file
-Dfile=filename.jar
-DgroupId=com.stackoverflow
-DartifactId=artifact
-Dversion=1.0.0
-Dpackaging=jar
-DcreateChecksum=true
-DgeneratePom=true
It's much easier to get those jars in your local repository using an internet connection and online mode.
It's possible to install these resource jars in your local maven repo using install-file. This will make the available to the build. You'll have to do this for each individually, but once that's done you won't have to do anything special.
To be clear, maven puts everything in your local repository, both the jar you're building with this project and the various library jars. Because your system cannot be connected to the internet to maven can populate the local repo with your libraries, you'll have to use this manual approach.
Edit: You should be able to run install-file anywhere. When you do, you'll need to provide the groupId, artifactId, version, and packaging using the command line options. If you already have a POM file for the library, you can provide that instead via -DpomFile=your-pom.xml.
