always: Maven will check for a newer version on every build.
#MVN CLEAN INSTALL DSKIPTESTS COMMAND UPDATE#
Maven provides you a way to can change this update policy in your repository definition: foo-repository. this library has been generated on 6 at 11:00:00) in your local repository, and if you run the Maven build again the same day, Maven will not check the repositories for a newer version. However, this check is made only once per day. That's why Maven will try to find a newer version in the remote repositories, even if a version of this library is found on the local repository. Now, if you need a library, Maven will know that this version is not stable and is subject to changes. Then, it will copy it into the local repository, to make it available for the next builds.įor example, a foo-1.0.jar library is considered as a stable version, and if Maven finds it in the local repository, it will use this one for the current build. If a stable version is not found there, it will search the remote repositories (defined in settings.xml or pom.xml) to retrieve this dependency. When you build an application, Maven will search for dependencies in the local repository.
