Choosing this option causes m2eclipse to skip index generation for a repository.This can come in handy if you have a series of repositories which you do not want to include in artifact searches.Every repository that m2eclipse uses is indexed by the Nexus Indexer.

You can manipulate the index that is associated with a Maven repository by right-clicking on a repository in the Maven Repositories view and selecting one of the following actions: This will rebuild an index for a local repository by iterating through the contents of a repository and recreating a Nexus index from scratch.

This can be a useful tool if there is another process outside of Eclipse that is going to be modifying a local Maven repository.

The Maven Repostitories view allows you to browse and manipulate your local Maven repository index.

m2eclipse maintains an index for the contents of your local repository, you can use this interface to browse artifacts that have been loaded into your local repository as shown in Figure 6.14, “Browsing Your Local Maven Repository”.

Switch it on if you rather edit the POM XML source directly instead of the POM form.

M2eclipse provides a label decorator that shows you the Maven version number on a project node in the project explorer. This tells Eclipse to resolve dependencies between workspace projects directly instead of going through the local Maven repository.

This folder contains the Central Maven repository under the repository identifier of "central".

It will also contain mirrors that have been configured in your Maven Settings ( If you have been using Maven, you are familiar with the Central Maven repository.

To do so, open the Maven Repositories view by going to under the Maven folder.

This folder contains any global Maven repositories that are referenced by all Maven projects.

The Maven Repositories view is also intelligent enough to keep track of any repositories that have been added to your project via your Maven Settings, an active Maven Profile, or that have been added directly to a project's POM.
