What is Central?

Terry Bernstein — Wed, 11 Jan 2012 16:20:53 +0000

“Central”, “Maven Central”, “The Central Repository”. You’ll here these terms a lot when discussing Java open source-based development. At Sonatype, we often take it for granted that everyone knows what we mean when we say “Central”. We know that’s not true, so we’ve put together this short video overview of Central and what it means to the Java community. Enjoy.

How to Create a Simple Project in m2eclipse

Tim O'Brien — Wed, 17 Feb 2010 08:00:04 +0000

One of the most compelling features of m2eclipse is the ability to quickly generate new Maven projects using the New Maven project wizard. This post and the associated video demonstrate the steps to create a simple Maven project using the New Maven project wizard to select the Maven Quickstart archetype.

To create a simple project using the New Maven project wizard:

Select File > New Project. This should display the “New Project” dialog.
In the “New Project” Dialog, expand the Maven folder, and select “Maven Project”.
Click Next. The next screen provides options for customizing the location of your new Maven project. If you are storing the new project in your workspace, you can supply the directory on this page.
Click Next. The next screen lists all of the available Maven Archetypes, select the Maven Quickstart Archetype which should be listed under the group id “org.apache.maven.archetypes”.
Click Next. On the next screen, supply a Group Id, Artifact Id, and Version for your new project.
Click Finish and m2eclipse will use the Maven Quickstart Archetype to generate a new Maven project in your Eclipse workspace.

Note about 0.9.8 Workspace Incompatibility: If you are using m2eclipse 0.10.0 with a workspace that contains projects created under m2eclipse 0.9.8, you must remove the workspaceState.ser file. The workspaceState.ser file is located within the workspace directory in $workspacedir/.metadata/.plugins/org.maven.ide.eclipse/workspaceState.ser. If you remove this file, m2eclipse 0.10.0 will regenerate it as needed.

How to Install m2eclipse Core Components

Tim O'Brien — Tue, 16 Feb 2010 09:00:40 +0000

To install m2eclipse, use the following Eclipse update site to install the core of the m2eclipse plugin. This Core update site contains a single component: “Maven Integration for Eclipse (Required)”. When you install this component you will be installing all of the core Wizards, the POM Editor, Maven Repository integration, and Maven integration. This post provides a set of detailed instructions for installing m2eclipse 0.10.0.

m2eclipse Core Update Site: http://m2eclipse.sonatype.org/sites/m2e

IMPORTANT NOTE: You cannot upgrade from m2eclipse 0.9.8 or m2eclipse 0.9.9 to m2eclipse 0.10.0. If you are running m2eclipse 0.9.8 or 0.9.9 you must either uninstall m2eclipse from your Eclipse installation or start with a fresh installation of Eclipse.

To install this plugin in the Eclipse IDE:

Select Help > Install New Software. This should display the “Install” dialog.
Paste the Update Site URL into the field named “Work with:” and press Enter. Pressing Enter should cause Eclipse to update list of available plugins and components.
Choose the component listed under m2eclipse: “Maven Integration for Eclipse (Required)”.
Click Next. Eclipse will then check to see if there are any issues which would prevent a successful installation.
Click Next and agree to the terms of the Eclipse Public License v1.0.
Click Finish to begin the installation process. Eclipse will then download and install the necessary components.
Once the installation process is finished, Eclipse will ask you if you want to restart the IDE. Sonatype strongly recommends that you restart your IDE after installing m2eclipse.
