+[[contributing]]
 == Contributing
 
-:spring-cloud-build-branch: master
-
-Spring Cloud is released under the non-restrictive Apache 2.0 license,
-and follows a very standard Github development process, using Github
-tracker for issues and merging pull requests into master. If you want
-to contribute even something trivial please do not hesitate, but
-follow the guidelines below.
-
-=== Sign the Contributor License Agreement
-Before we accept a non-trivial patch or pull request we will need you to sign the
-https://cla.pivotal.io/sign/spring[Contributor License Agreement].
-Signing the contributor's agreement does not grant anyone commit rights to the main
-repository, but it does mean that we can accept your contributions, and you will get an
-author credit if we do.  Active contributors might be asked to join the core team, and
-given the ability to merge pull requests.
-
-=== Code of Conduct
-This project adheres to the Contributor Covenant https://github.com/spring-cloud/spring-cloud-build/blob/master/docs/src/main/asciidoc/code-of-conduct.adoc[code of
-conduct]. By participating, you  are expected to uphold this code. Please report
-unacceptable behavior to spring-code-of-conduct@pivotal.io.
-
-=== Code Conventions and Housekeeping
-None of these is essential for a pull request, but they will all help.  They can also be
-added after the original pull request but before a merge.
-
-* Use the Spring Framework code format conventions. If you use Eclipse
-  you can import formatter settings using the
-  `eclipse-code-formatter.xml` file from the
-  https://raw.githubusercontent.com/spring-cloud/spring-cloud-build/master/spring-cloud-dependencies-parent/eclipse-code-formatter.xml[Spring
-  Cloud Build] project. If using IntelliJ, you can use the
-  https://plugins.jetbrains.com/plugin/6546[Eclipse Code Formatter
-  Plugin] to import the same file.
-* Make sure all new `.java` files to have a simple Javadoc class comment with at least an
-  `@author` tag identifying you, and preferably at least a paragraph on what the class is
-  for.
-* Add the ASF license header comment to all new `.java` files (copy from existing files
-  in the project)
-* Add yourself as an `@author` to the .java files that you modify substantially (more
-  than cosmetic changes).
-* Add some Javadocs and, if you change the namespace, some XSD doc elements.
-* A few unit tests would help a lot as well -- someone has to do it.
-* If no-one else is using your branch, please rebase it against the current master (or
-  other target branch in the main project).
-* When writing a commit message please follow https://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html[these conventions],
-  if you are fixing an existing issue please add `Fixes gh-XXXX` at the end of the commit
-  message (where XXXX is the issue number).
-
-=== Checkstyle
-
-Spring Cloud Build comes with a set of checkstyle rules. You can find them in the `spring-cloud-build-tools` module. The most notable files under the module are:
-
-.spring-cloud-build-tools/
-----
-└── src
-    ├── checkstyle
-    │   └── checkstyle-suppressions.xml <3>
-    └── main
-        └── resources

-            └── checkstyle.xml <1>
-----
-<1> Default Checkstyle rules
-<2> File header setup
-<3> Default suppression rules
-
-==== Checkstyle configuration
-
-Checkstyle rules are *disabled by default*. To add checkstyle to your project just define the following properties and plugins.
-
-.pom.xml
-----
-<properties>
-<maven-checkstyle-plugin.failsOnError>true</maven-checkstyle-plugin.failsOnError> <1>
-        <maven-checkstyle-plugin.failsOnViolation>true

-----
-<1> Fails the build upon Checkstyle errors
-<2> Fails the build upon Checkstyle violations
-<3> Checkstyle analyzes also the test sources
-<4> Add the Spring Java Format plugin that will reformat your code to pass most of the Checkstyle formatting rules
-<5> Add checkstyle plugin to your build and reporting phases
-
-If you need to suppress some rules (e.g. line length needs to be longer), then it's enough for you to define a file under `${project.root}/src/checkstyle/checkstyle-suppressions.xml` with your suppressions. Example:
-
-.projectRoot/src/checkstyle/checkstyle-suppresions.xml
-----
-<?xml version="1.0"?>
-<!DOCTYPE suppressions PUBLIC
-		"-//Puppy Crawl//DTD Suppressions 1.1//EN"
-		"https://www.puppycrawl.com/dtds/suppressions_1_1.dtd">
-<suppressions>
-	<suppress files=".*ConfigServerApplication\.java" checks="HideUtilityClassConstructor"/>
-	<suppress files=".*ConfigClientWatch\.java" checks="LineLengthCheck"/>
-</suppressions>
-----
-
-It's advisable to copy the `${spring-cloud-build.rootFolder}/.editorconfig` and `${spring-cloud-build.rootFolder}/.springformat` to your project. That way, some default formatting rules will be applied. You can do so by running this script:
-
-```bash
-$ curl https://raw.githubusercontent.com/spring-cloud/spring-cloud-build/master/.editorconfig -o .editorconfig
-$ touch .springformat
-```
-
-=== IDE setup
-
-==== Intellij IDEA
-
-In order to setup Intellij you should import our coding conventions, inspection profiles and set up the checkstyle plugin.
-The following files can be found in the https://github.com/spring-cloud/spring-cloud-build/tree/master/spring-cloud-build-tools[Spring Cloud Build] project.

-
-Go to `File` -> `Settings` -> `Editor` -> `Code style`. There click on the icon next to the `Scheme` section. There, click on the `Import Scheme` value and pick the `Intellij IDEA code style XML` option. Import the `spring-cloud-build-tools/src/main/resources/intellij/Intellij_Spring_Boot_Java_Conventions.xml` file.
-
-.Inspection profiles
-
-image::https://raw.githubusercontent.com/spring-cloud/spring-cloud-build/{spring-cloud-build-branch}/docs/src/main/asciidoc/images/intellij-inspections.png[Code style]
-
-Go to `File` -> `Settings` -> `Editor` -> `Inspections`. There click on the icon next to the `Profile` section. There, click on the `Import Profile` and import the `spring-cloud-build-tools/src/main/resources/intellij/Intellij_Project_Defaults.xml` file.
-
-.Checkstyle
-
-To have Intellij work with Checkstyle, you have to install the `Checkstyle` plugin. It's advisable to also install the `Assertions2Assertj` to automatically convert the JUnit assertions
-
-image::https://raw.githubusercontent.com/spring-cloud/spring-cloud-build/{spring-cloud-build-branch}/docs/src/main/asciidoc/images/intellij-checkstyle.png[Checkstyle]
-
-Go to `File` -> `Settings` -> `Other settings` -> `Checkstyle`. There click on the `+` icon in the `Configuration file` section. There, you'll have to define where the checkstyle rules should be picked from. In the image above, we've picked the rules from the cloned Spring Cloud Build repository. 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/master/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.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.
-
-=== Duplicate Finder
-
-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
-

-|Name | Default | Description
-
-|eureka.client.eureka-connection-idle-timeout-seconds | `+++30+++` | Indicates how much time (in seconds) that the HTTP connections to eureka server can stay idle before it can be closed. In the AWS environment, it is recommended that the values is 30 seconds or less, since the firewall cleans up the connection information after a few mins leaving the connection hanging in limbo.
-|eureka.client.eureka-server-connect-timeout-seconds | `+++5+++` | Indicates how long to wait (in seconds) before a connection to eureka server needs to timeout. Note that the connections in the client are pooled by {@link HttpClient} and this setting affects the actual connection creation and also the wait time to get the connection from the pool.
-|eureka.client.eureka-server-d-n-s-name |  | Gets the DNS name to be queried to get the list of eureka servers.This information is not required if the contract returns the service urls by implementing serviceUrls. The DNS mechanism is used when useDnsForFetchingServiceUrls is set to true and the eureka client expects the DNS to configured a certain way so that it can fetch changing eureka servers dynamically. The changes are effective at runtime.
-|eureka.client.eureka-server-port |  | Gets the port to be used to construct the service url to contact eureka server when the list of eureka servers come from the DNS.This information is not required if the contract returns the service urls eurekaServerServiceUrls(String). The DNS mechanism is used when useDnsForFetchingServiceUrls is set to true and the eureka client expects the DNS to configured a certain way so that it can fetch changing eureka servers dynamically. The changes are effective at runtime.
-|eureka.client.eureka-server-read-timeout-seconds | `+++8+++` | Indicates how long to wait (in seconds) before a read from eureka server needs to timeout.
-|eureka.client.eureka-server-total-connections | `+++200+++` | Gets the total number of connections that is allowed from eureka client to all eureka servers.
-|eureka.client.eureka-server-total-connections-per-host | `+++50+++` | Gets the total number of connections that is allowed from eureka client to a eureka server host.
-|eureka.client.eureka-server-u-r-l-context |  | Gets the URL context to be used to construct the service url to contact eureka server when the list of eureka servers come from the DNS. This information is not required if the contract returns the service urls from eurekaServerServiceUrls. The DNS mechanism is used when useDnsForFetchingServiceUrls is set to true and the eureka client expects the DNS to configured a certain way so that it can fetch changing eureka servers dynamically. The changes are effective at runtime.
-|eureka.client.eureka-service-url-poll-interval-seconds | `+++0+++` | Indicates how often(in seconds) to poll for changes to eureka server information. Eureka servers could be added or removed and this setting controls how soon the eureka clients should know about it.
-|eureka.client.prefer-same-zone-eureka | `+++true+++` | Indicates whether or not this instance should try to use the eureka server in the same zone for latency and/or other reason. Ideally eureka clients are configured to talk to servers in the same zone The changes are effective at runtime at the next registry fetch cycle as specified by registryFetchIntervalSeconds
-|eureka.client.register-with-eureka | `+++true+++` | Indicates whether or not this instance should register its information with eureka server for discovery by others. In some cases, you do not want your instances to be discovered whereas you just want do discover other instances.
-|eureka.server.peer-eureka-nodes-update-interval-ms | `+++0+++` | 
-|eureka.server.peer-eureka-status-refresh-time-interval-ms | `+++0+++` | 
-|ribbon.eureka.enabled | `+++true+++` | Enables the use of Eureka with Ribbon.
-|spring.cloud.loadbalancer.eureka.approximate-zone-from-hostname | `+++false+++` | Used to determine whether we should try to get the `zone` value from host name.
