Note: Older versions of the maven dependency plugin had a manual-purge-local-repository goal, which is now (version 2.8) implied by the use of manualInclude.

The full documentation is in the maven-dependency-plugin spec. If you are running with a non-standard cache location, or on multiple platforms, these are more reliable than deleting files "by hand". The documentation implies that this does not remove transitive dependencies by default. The JARs must be placed in the local repository in the correct place in order for it to be correctly picked up by Apache Maven. This relative path shall be relative to project root. Occasionally, you will have 3rd party JARs that you need to put in your local repository for use in your builds, since they don't exist in any public repository like Maven Central.
#Maven install jar local repository example code#
If parent POM file is not located in any other place, then you can use code tag.
For example, from the command line: mvn dependency:purge-local-repository -DmanualInclude="groupId:artifactId. By default, Maven looks for the parent POM first at project’s root, then the local repository, and lastly in the remote repository. If you want to explicitly remove a single artifact from the cache, use purge-local-repository with the manualInclude parameter.
Also transitive dependencies will be purged (locally) as well, by default. Assume i have downloaded gson-2.2.4. This should be used as part of a project phase because it applies to the dependencies for the containing project. Eg:Lets get google gson library as an example, This is already available in maven repository but here we are going to manually install it to our local m2 repo.
Optionally, you may re-resolve them from the remote repositories at the same time. To install a JAR in the local repository use the following command: mvn install:install-file -DfileThe goal purge-local-repository, on the standard Maven dependency plugin, will remove the locally installed dependencies of this project from your cache. Although deleting files manually works, there is an official way of removing dependencies of your project from your local (cache) repository and optionally re-resolving them from remote repositories.
