However, you can point to the Spring Cloud Build's GitHub repository (e.g. for the `checkstyle.xml` : `https://raw.githubusercontent.com/spring-cloud/spring-cloud-build/main/spring-cloud-build-tools/src/main/resources/checkstyle.xml`). We need to provide the following variables:
 
-- `checkstyle.header.file` - please point it to the Spring Cloud Build's, `spring-cloud-build-tools/src/main/resources/checkstyle-header.txt` file either in your cloned repo or via the `https://raw.githubusercontent.com/spring-cloud/spring-cloud-build/master/spring-cloud-build-tools/src/main/resources/checkstyle-header.txt` URL.
-- `checkstyle.suppressions.file` - default suppressions. Please point it to the Spring Cloud Build's, `spring-cloud-build-tools/src/checkstyle/checkstyle-suppressions.xml` file either in your cloned repo or via the `https://raw.githubusercontent.com/spring-cloud/spring-cloud-build/master/spring-cloud-build-tools/src/checkstyle/checkstyle-suppressions.xml` URL.
+- `checkstyle.header.file` - please point it to the Spring Cloud Build's, `spring-cloud-build-tools/src/main/resources/checkstyle-header.txt` file either in your cloned repo or via the `https://raw.githubusercontent.com/spring-cloud/spring-cloud-build/main/spring-cloud-build-tools/src/main/resources/checkstyle-header.txt` URL.
+- `checkstyle.suppressions.file` - default suppressions. Please point it to the Spring Cloud Build's, `spring-cloud-build-tools/src/checkstyle/checkstyle-suppressions.xml` file either in your cloned repo or via the `https://raw.githubusercontent.com/spring-cloud/spring-cloud-build/main/spring-cloud-build-tools/src/checkstyle/checkstyle-suppressions.xml` URL.
 - `checkstyle.additional.suppressions.file` - this variable corresponds to suppressions in your local project. E.g. you're working on `spring-cloud-contract`. Then point to the `project-root/src/checkstyle/checkstyle-suppressions.xml` folder. Example for `spring-cloud-contract` would be: `/home/username/spring-cloud-contract/src/checkstyle/checkstyle-suppressions.xml`.
 
 IMPORTANT: Remember to set the `Scan Scope` to `All sources` since we apply checkstyle rules for production and test sources.

+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 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`.

-The idea of this script is to update gh-pages branch with the generated docs. Without any options
-the script will work in the following manner:
-
-- if there's no gh-pages / target for docs module then the script ends
-- for master branch the generated docs are copied to the root of gh-pages branch
-- for any other branch (if that branch is whitelisted) a subfolder with branch name is created
-    and docs are copied there
-- if the version switch is passed (-v) then a tag with (v) prefix will be retrieved and a folder
-    with that version number will be created in the gh-pages branch. WARNING! No whitelist verification will take place
-- if the destination switch is passed (-d) then the script will check if the provided dir is a git repo and then will
-    switch to gh-pages of that repo and copy the generated docs to [docs/<project-name>/<version>]
-- if the destination switch is passed (-d) then the script will check if the provided dir is a git repo and then will
-    switch to gh-pages of that repo and copy the generated docs to [docs/<project-name>/<version>]
-- if the release train switch is passed (-r) then the script will check if the provided dir is a git repo and then will
-    switch to gh-pages of that repo and copy the generated docs to [docs/<version>]
-
-USAGE:
-
-You can use the following options:
-
--v|--version        - the script will apply the whole procedure for a particular library version
--r|--releasetrain   - instead of nesting the docs under the project_name/version folder the docs will end up in version
--d|--destination    - the root of destination folder where the docs should be copied. You have to use the full path.
-                        E.g. point to spring-cloud-static folder. Can't be used with (-c)
--b|--build          - will run the standard build process after checking out the branch
--c|--clone          - will automatically clone the spring-cloud-static repo instead of providing the destination.
-                        Obviously can't be used with (-d)

-The idea of this script is to keep the Spring guides up to date by taking the
-contents of guides from the project's repository and pushing them to Spring guides
-repository.
-
-This script iterates over the contents of the [guides] folder. Each its subfolder
-corresponds to a repository under the Spring Guides repository (i.e. the https://github.com/spring-guides organization).
-
-Upon the iteration a corresponding guide repository gets cloned and updated with the latest content from the project repository. A commit and push then takes place.
-
-USAGE:
-
-You can use the following options:
-
--h|--help           - display this message

-
-This sample hook safeguards topic branches that have been
-published from being rewound.
-
-The workflow assumed here is:
-
- * Once a topic branch forks from "master", "master" is never
-   merged into it again (either directly or indirectly).
-
- * Once a topic branch is fully cooked and merged into "master",
-   it is deleted.  If you need to build on top of it to correct
-   earlier mistakes, a new topic branch is created by forking at
-   the tip of the "master".  This is not strictly necessary, but
-   it makes it easier to keep your history simple.
-
- * Whenever you need to test or publish your changes to topic
-   branches, merge them into "next" branch.
-
-The script, being an example, hardcodes the publish branch name
-to be "next", but it is trivial to make it configurable via
-$GIT_DIR/config mechanism.
-
-With this workflow, you would want to know:
-
-(1) ... if a topic branch has ever been merged to "next".  Young
-    topic branches can have stupid mistakes you would rather
-    clean up before publishing, and things that have not been
-    merged into other branches can be easily rebased without
-    affecting other people.  But once it is published, you would
-    not want to rewind it.
-
-(2) ... if a topic branch has been fully merged to "master".
-    Then you can delete it.  More importantly, you should not
-    build on top of it -- other people may already want to
-    change things related to the topic as patches against your
-    "master", so if you need further changes, it is better to
-    fork the topic (perhaps with the same name) afresh from the
-    tip of "master".
-
-Let's look at this example:
-
-		   o---o---o---o---o---o---o---o---o---o "next"
-		  /       /           /           /
-		 /   a---a---b A     /           /
-		/   /               /           /
-	       /   /   c---c---c---c B         /
-	      /   /   /             \         /
-	     /   /   /   b---b C     \       /
-	    /   /   /   /             \     /
-    ---o---o---o---o---o---o---o---o---o---o---o "master"
-
-
-A, B and C are topic branches.
-
- * A has one fix since it was merged up to "next".
-
- * B has finished.  It has been fully merged up to "master" and "next",
-   and is ready to be deleted.
-
- * C has not merged to "next" at all.
-
-We would want to allow C to be rebased, refuse A, and encourage
-B to be deleted.
-
-To compute (1):
-
-	git rev-list ^master ^topic next
-	git rev-list ^master        next
-
-	if these match, topic has not merged in next at all.
-
-To compute (2):
-
-	git rev-list master..topic
-
-	if this is empty, it is fully merged to "master".

+
+Spring Cloud Build is a common utility project for Spring Cloud
+to use for plugin and dependency management.
+
+== Building and Deploying
+
+To install locally:
+
+----
+
+$ mvn install -s .settings.xml
+----
+
+and to deploy snapshots to repo.spring.io:
+
+----
+$ mvn deploy -DaltSnapshotDeploymentRepository=repo.spring.io::default::https://repo.spring.io/libs-snapshot-local
+----
+
+for a RELEASE build use
+
+----
+$ mvn deploy -DaltReleaseDeploymentRepository=repo.spring.io::default::https://repo.spring.io/libs-release-local
+----
+
+and for jcenter use
+
+----
+$ mvn deploy -DaltReleaseDeploymentRepository=bintray::default::https://api.bintray.com/maven/spring/jars/org.springframework.cloud:build
+----
+
+and for Maven Central use
+
+----
+$ mvn deploy -P central -DaltReleaseDeploymentRepository=sonatype-nexus-staging::default::https://oss.sonatype.org/service/local/staging/deploy/maven2
+----
+
+(the "central" profile is available for all projects in Spring Cloud and it sets up the gpg jar signing, and the repository has to be specified separately for this project because it is a parent of the starter parent which users in turn have as their own parent).
+
+== Contributing
+
+include::https://raw.githubusercontent.com/spring-cloud/spring-cloud-build/main/docs/modules/ROOT/partials/contributing.adoc[]
+
+== Flattening the POMs
+
+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.
+
+In order to add it, add the `org.codehaus.mojo:flatten-maven-plugin` to your `pom.xml`.
+
+[source,xml]
+----
+<build>
+	<plugins>
+		<plugin>
+			<groupId>org.codehaus.mojo</groupId>
+			<artifactId>flatten-maven-plugin</artifactId>
+		</plugin>
+	</plugins>
+</build>
+----
+
+== Reusing the documentation
+
+Spring Cloud Build publishes its `spring-cloud-build-docs` module that contains
+helpful scripts (e.g. README generation ruby script) and css, xslt and images
+for the Spring Cloud documentation. If you want to follow the same convention
+approach of generating documentation just add these plugins to your `docs` module
+
+[source,xml]

+----
+<1> This plugin downloads sets up all the git information of the project
+<2> This plugin downloads the resources of the `spring-cloud-build-docs` module
+<3> This plugin unpacks the resources of the `spring-cloud-build-docs` module
+<4> This plugin generates an `adoc` file with all the configuration properties from the classpath
+<5> This plugin is required to parse the Asciidoctor documentation
+<6> This plugin is required to copy resources into proper final destinations and to generate main README.adoc and to assert that no files use unresolved links
+<7> This plugin ensures that the generated zip docs will get published
+
+IMPORTANT: The order of plugin declaration is important!
+
+In order for the build to generate the `adoc` file with all your configuration properties, your `docs` module should contain all the dependencies on the classpath, that you would want to scan for configuration properties. The file will be output to `${docsModule}/src/main/asciidoc/_configprops.adoc` file (configurable via the `configprops.path` property).
+
+If you want to modify which of the configuration properties are put in the table, you can tweak the `configprops.inclusionPattern` pattern to include only a subset of the properties (e.g. `<configprops.inclusionPattern>spring.sleuth.*</configprops.inclusionPattern>`).
+
+Spring Cloud Build Docs comes with a set of attributes for asciidoctor that you can reuse.
+
+[source,xml]
+----
+include::https://raw.githubusercontent.com/spring-cloud/spring-cloud-build/main/docs/pom.xml[tags=docs,indent=0]
+----
+
+== Updating the guides
+
+We assume that your project contains guides under the `guides` folder.
+
+```
+.
+└── guides
+	├── gs-guide1
+	├── gs-guide2
+	└── gs-guide3
+```
+
+This means that the project contains 3 guides that would
+correspond to the following guides in Spring Guides org.
+
+- https://github.com/spring-guides/gs-guide1
+- https://github.com/spring-guides/gs-guide2
+- https://github.com/spring-guides/gs-guide3
+
+If you deploy your project with the `-Pguides` profile like this
+
+```
+$ ./mvnw clean deploy -Pguides
+```
+
+what will happen is that for GA project versions, we will clone `gs-guide1`, `gs-guide2` and `gs-guide3` and update their contents with the ones being under your `guides` project.
+
+You can skip this by either not adding the `guides` profile, or passing the `-DskipGuides` system property when the profile is turned on.
+
+You can configure the project version passed to guides via the `guides-project.version` (defaults to `${project.version}`). The phase at which guides get updated can be configured by `guides-update.phase` (defaults to `deploy`).
