Now you can add this jar as a dependency as normal: ĭont forget to add and commit your local repo folder to git. When using the repository from a sub-module, you will need to substitute the $ property in the element. You may have to create the element if you dont have one. Now edit your pom.xml and add this repository to your element. Your project will contain some Maven metadata and your JAR file. Maven can deploy the artifact for you using the mvn deploy:deploy-file goal: mvn deploy:deploy-file -Durl=file:///path/to/yourproject/repo/ -Dfile=mylib-1.0.jar -DgroupId=com.example -DartifactId=mylib -Dpackaging=jar -Dversion=1.0 Your project root should look something like this to start with: yourprojectĪdd a standard Maven repository directory called repo for the group com.example and version 1.0: yourproject version: 1.0 (or whatever version your lib is, if you have it versioned)Ĭreate a local Maven repository directory.These parameters may not matter to you, but Maven requires this information for all dependencies. First you must define a groupId, artifactId and version for the library. Let’s say your app depends on the library mylib.jar which is not in any public Maven repository. Pick groupId, artifactId and version parameters

This guide shows you how to add these unmanaged libraries in your application project and tell Maven how to find them. Some Java applications have dependencies that aren’t available in a public or private Maven repository (the latter of which can be accessed using a custom settings.xml file). Create a local Maven repository directory.Pick groupId, artifactId and version parameters.It works only for dependencies used directly by the project itself. These dependencies are not downloaded by the dependency:go-offline goal.

Namely, if you empty the entire repository folder, it means you will be discarding also the required dependencies of the default maven plugins ( plus eventual dynamic dependencies inside the plugins). This state of affairs brought some issues to itself.
#Maven install dependencies locally download#
To have a clean state for maven, the content of ~/.m2/repository was emptied so that after switching to new repository it will download fresh the artifacts it needs. My use case involved switching between maven repository dynamically.

This is done with the help of a flag passed to mvn command: -o, -offlineĭocumentation for the command line flags can be found here: Īs an example for the install goal, you would do: mvn -o install More to the story
We need to instruct maven that we don’t need to use the network and we need to work offline. Now they are all stored in your local repository InstallĪs mentioned, even if you have all the dependencies in the local repository, maven will still go to the network and check if everything is up-to-date.
Once you run this, you’ll see how to required dependencies are downloaded. You need to execute this goal on your project (i.e.: navigate to project folder and then ‚mvn dependency:go-offline‘) To download all the dependencies up-front maven offers „dependency:go-offline“ goal. In my case, I needed to download all the needed dependencies in the local repository up-front and later on to execute the install goal on the maven project. Since you still need the dependencies, this implies a two step process: Download required dependencies & Actually execute the required goal. You need to tell maven to stop trying to synchronize or download the required dependencies. However, in some cases you need to work offline. If the dependency is already downloaded, it only connects to the remote repository for synchronization purposes. It allows you to quickly specify a dependency in the pom.xml file and forget about it.
