Maven repository

As stewards of Central for nearly 20 years and inventors of both software supply chain management and Nexus Repository, Sonatype knows that the integrity of your build is critical. Cache, maven repository, publish, and distribute components with your teams.

This section explains the default configuration included in Nexus Repository Manager Pro and Nexus Repository Manager OSS, instructions for creating further Maven repositories as well as searching and browsing the repositories. The configuration examples take advantage of the repository manager merging many repositories and exposing them via a repository group. Apache Maven created the most widely used repository format in the Java development ecosystem with the release of Apache Maven 2. The format is used by many publicly available repositories. It is configured as a proxy repository by default in Apache Maven and widely used in other tools. In addition to the generic repository management features documented in Repository Management , specifics of the Maven repository format can be configured for each repository in the Maven 2 section:.

Maven repository

Local and remote repositories are structured the same way so that scripts can run on either side, or they can be synced for offline use. The layout of the repositories is completely transparent to the Maven user, however. In general, you should not need to do anything with the local repository on a regular basis, except clean it out if you are short on disk space or erase it completely if you are willing to download everything again. For the remote repositories, they are used for both downloading and uploading if you have the permission to do so. Downloading in Maven is triggered by a project declaring a dependency that is not present in the local repository or for a SNAPSHOT , when the remote repository contains one that is newer. By default, Maven will download from the central repository. To override this, you need to specify a mirror as shown in Using Mirrors for Repositories. You can set this in your settings. However, it is common for a project to customise the repository in its pom. If dependencies are not being found, check that you have not overridden the remote repository. For more information on dependencies, see Dependency Mechanism. There are several official Central repositories geographically distributed.

A hosted Maven repository can be used to deploy your own as well as third-party components.

Then, install the packages whenever you need to use them as a dependency. You need a token to publish a package. For more information, review the guidance on tokens. Do not use authentication methods other than the methods documented here. Undocumented authentication methods might be removed in the future. Add the following section to your settings.

Maven is a build automation tool used primarily for Java projects. Maven can also be used to build and manage projects written in C , Ruby , Scala , and other languages. Maven addresses two aspects of building software: how software is built and its dependencies. Unlike earlier tools like Apache Ant , it uses conventions for the build procedure. Only exceptions need to be specified. An XML file describes the software project being built, its dependencies on other external modules and components, the build order, directories, and required plug-ins. It comes with pre-defined targets for performing certain well-defined tasks such as compilation of code and its packaging.

Maven repository

Apache Maven is a software project management and comprehension tool. Based on the concept of a project object model POM , Maven can manage a project's build, reporting and documentation from a central piece of information. If you think that Maven could help your project, you can find out more information in the "About Maven" section of the navigation. This includes an in-depth description of what Maven is and a list of some of its main features. This site is separated into the following sections, depending on how you'd like to use Maven:. Each guide is divided into a number of trails to get you started on a particular topic, and includes a reference area and a "cookbook" of common examples. You can access the guides at any time from the left navigation. If you are looking for a quick reference, you can use the documentation index. To get started, search the documentation, issue management system , the wiki or the mailing list archives to see if the problem has been solved or reported before. If the problem has not been reported before, the recommended way to get help is to subscribe to the Maven Users Mailing list.

By default, Maven will download from the central repository. To deploy build outputs to a repository with the publish task, user credentials can be declared in the build. Published 9 days ago. In case there are not enough permissions to read the most recently-published package than Forbidden is returning. A repository group is the recommended way to expose all your Maven repositories from the repository manager to your users, without needing any further client side configuration. Layout Policy. Published 8 days ago. If you are temporarily disconnected from the internet and you need to build your projects offline, you can use the offline switch on the CLI:. Add Maven repositories to the Members list in the desired order. By default, new Maven repositories are as assigned a Content-Disposition header of Inline. A typical, useful example is the maven-public group that is configured by default. Advanced Options.

Some examples are resolving Javadoc links and link checking the site. Grouping Maven Repositories. You can make changes to your settings. The integration test runs for Apache Maven itself require this setting. For guidance on publishing to Maven, see Gradle's documentation. The format is used by many publicly available repositories. Specify where to find the user settings -s,--settings instead of the default location. For more information on creating and deploying sites, see Creating a Site. Attachment Indicates repository content should be provided as an attachment that a user downloads. Version Maven forwarding is restricted to only the project level and group level endpoints. Alternatively, look at -B,--batch-mode or lower level logging changes. Request support. Version 1.
