-contain repository declarations for spring pre-release artifacts.
-
-NOTE: Be aware that you might need to increase the amount of memory
-available to Maven by setting a `MAVEN_OPTS` environment variable with
-a value like `-Xmx512m -XX:MaxPermSize=128m`. We try to cover this in

-=== Documentation
-
-The spring-cloud-build module has a "docs" profile, and if you switch
-that on it will try to build asciidoc sources from
-`src/main/asciidoc`. As part of that process it will look for a
-`README.adoc` and process it by loading all the includes, but not
-parsing or rendering it, just copying it to `${main.basedir}`
-(defaults to `${basedir}`, i.e. the root of the project). If there are
-any changes in the README it will then show up after a Maven build as
-a modified file in the correct place. Just commit it and push the change.
-
-=== Working with the code
-If you don't have an IDE preference we would recommend that you use
-https://www.springsource.com/developer/sts[Spring Tools Suite] or
-https://eclipse.org[Eclipse] when working with the code. We use the
-https://eclipse.org/m2e/[m2eclipse] eclipse plugin for maven support. Other IDEs and tools
-should also work without issue as long as they use Maven 3.3.3 or better.
-
-==== Activate the Spring Maven profile
-Spring Cloud projects require the 'spring' Maven profile to be activated to resolve
-the spring milestone and snapshot repositories. Use your preferred IDE to set this
-profile to be active, or you may experience build errors.
-
-==== Importing into eclipse with m2eclipse
-We recommend the https://eclipse.org/m2e/[m2eclipse] eclipse plugin when working with
-eclipse. If you don't already have m2eclipse installed it is available from the "eclipse
-marketplace".
-
-NOTE: Older versions of m2e do not support Maven 3.3, so once the
-projects are imported into Eclipse you will also need to tell
-m2eclipse to use the right profile for the projects.  If you
-see many different errors related to the POMs in the projects, check
-that you have an up to date installation.  If you can't upgrade m2e,
-add the "spring" profile to your `settings.xml`. Alternatively you can
-copy the repository settings from the "spring" profile of the parent
