+Spring Cloud Build brings along the  `basepom:duplicate-finder-maven-plugin`, that enables flagging duplicate and conflicting classes and resources on the java classpath.
+
+==== Duplicate Finder configuration
+
+Duplicate finder is *enabled by default* and will run in the `verify` phase of your Maven build, but it will only take effect in your project if you add the `duplicate-finder-maven-plugin` to the `build` section of the projecst's `pom.xml`.

 To avoid propagating build setup that is required to build a Spring Cloud project, we're using the maven flatten plugin. It has the advantage of letting you use whatever features you need while publishing "clean" pom to the repository.

-=== Basic Compile and Test

-$ ./mvnw install
-----
-
-NOTE: You can also install Maven (>=3.3.3) yourself and run the `mvn` command
-in place of `./mvnw` in the examples below. If you do that you also
-might need to add `-P spring` if your local Maven settings do not
-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
-the `.mvn` configuration, so if you find you have to do it to make a
-build succeed, please raise a ticket to get the settings added to
-source control.
-
-For hints on how to build the project look in `.travis.yml` if there
-is one. There should be a "script" and maybe "install" command. Also
-look at the "services" section to see if any services need to be
-running locally (e.g. mongo or rabbit).  Ignore the git-related bits
-that you might find in "before_install" since they're related to setting git
-credentials and you already have those.
-
-The projects that require middleware generally include a
-`docker-compose.yml`, so consider using
-https://docs.docker.com/compose/[Docker Compose] to run the middeware servers
-in Docker containers. See the README in the
-https://github.com/spring-cloud-samples/scripts[scripts demo
-repository] for specific instructions about the common cases of mongo,
-rabbit and redis.
-
-NOTE: If all else fails, build with the command from `.travis.yml` (usually
-`./mvnw install`).
-
-=== 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
-pom into your `settings.xml`.
-

-If you prefer not to use m2eclipse you can generate eclipse project metadata using the
-following command:
