 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.header.file` - please point it to the Spring Cloud Build's, `spring-cloud-build-tools/src/main/resources/checkstyle/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.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`.

 [[spring-cloud-feign-overriding-defaults]]
 === Overriding Feign Defaults

 A central concept in Spring Cloud's Feign support is that of the named client. Each feign client is part of an ensemble of components that work together to contact a remote server on demand, and the ensemble has a name that you give it as an application developer using the `@FeignClient` annotation. Spring Cloud creates a new ensemble as an
 `ApplicationContext` on demand for each named client using `FeignClientsConfiguration`. This contains (amongst other things) an `feign.Decoder`, a `feign.Encoder`, and a `feign.Contract`.
-It is possible to override the name of that ensemble by using the `contextId`
-attribute of the `@FeignClient` annotation.

 Spring Cloud lets you take full control of the feign client by declaring additional configuration (on top of the `FeignClientsConfiguration`) using `@FeignClient`. Example:

-
-Spring Cloud OpenFeign provides an equivalent `@SpringQueryMap` annotation, which

-
-[source,java,indent=0]
----
-// Params.java
-public class Params {
-    private String param1;

-
-=== HATEOAS support
-
-Spring provides some APIs to create REST representations that follow the https://en.wikipedia.org/wiki/HATEOAS[HATEOAS] principle, https://spring.io/projects/spring-hateoas[Spring Hateoas] and https://spring.io/projects/spring-data-rest[Spring Data REST].
-
-If your project use the `org.springframework.boot:spring-boot-starter-hateoas` starter
-or the `org.springframework.boot:spring-boot-starter-data-rest` starter, Feign HATEOAS support is enabled by default.
-
-When HATEOAS support is enabled, Feign clients are allowed to serialize
-and deserialize HATEOAS representation models: https://docs.spring.io/spring-hateoas/docs/1.0.0.M1/apidocs/org/springframework/hateoas/EntityModel.html[EntityModel], https://docs.spring.io/spring-hateoas/docs/1.0.0.M1/apidocs/org/springframework/hateoas/CollectionModel.html[CollectionModel] and https://docs.spring.io/spring-hateoas/docs/1.0.0.M1/apidocs/org/springframework/hateoas/PagedModel.html[PagedModel].

----
-@FeignClient("demo")
-public interface DemoTemplate {
-
-    @GetMapping(path = "/stores")
-    CollectionModel<Store> getStores();
-}
----
-
-=== Spring @MatrixVariable Support
-
-Spring Cloud OpenFeign provides support for the Spring `@MatrixVariable` annotation.
-
-If a map is passed as the method argument, the `@MatrixVariable` path segment is created by joining key-value pairs from the map with a `=`.
-
-If a different object is passed, either the `name` provided in the `@MatrixVariable` annotation (if defined) or the annotated variable name is
-joined with the provided method argument using `=`.
-
-IMPORTANT:: Even though, on the server side, Spring does not require the users to name the path segment placeholder same as the matrix variable name, since it would be too ambiguous on the client side, Sprig Cloud OpenFeign requires that you add a path segment placeholder with a name matching either the `name` provided in the `@MatrixVariable` annotation (if defined) or the annotated variable name.
-
-For example:
-
-[source,java,indent=0]
----
-@GetMapping("/objects/links/{matrixVars}")
-Map<String, List<String>> getObjects(@MatrixVariable Map<String, List<String>> matrixVars);
----
-Note that both variable name and the path segment placeholder are called `matrixVars`.
-
-[source,java,indent=0]
----
-@FeignClient("demo")
-public interface DemoTemplate {
-
-    @GetMapping(path = "/stores")
-    CollectionModel<Store> getStores();
-}
----
-
-=== Feign `CollectionFormat` support
-We support `feign.CollectionFormat` by providing the `@CollectionFormat` annotation. You can annotate a Feign client method with it by passing the desired `feign.CollectionFormat` as annotation value.
-
-In the following example, the `CSV` format is used instead of the default `EXPLODED` to process the method.
-
-[source,java,indent=0]
----
-@FeignClient(name = "demo")
-	protected interface PageableFeignClient {
-
-		@CollectionFormat(feign.CollectionFormat.CSV)
-		@GetMapping(path = "/page")
-		ResponseEntity performRequest(Pageable page);
-
-	}
----
-
-TIP: Set the `CSV` format while sending `Pageable` as a query parameter in order for it to be encoded correctly.
-
-=== Reactive Support
-As the https://github.com/OpenFeign/feign[OpenFeign project] does not currently support reactive clients, such as https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/web/reactive/function/client/WebClient.html[Spring WebClient], neither does Spring Cloud OpenFeign. We will add support for it here as soon as it becomes available in the core project.
-
-Until that is done, we recommend using https://github.com/Playtika/feign-reactive[feign-reactive] for Spring WebClient support.
-
-==== Early Initialization Errors
-
-Depending on how you are using your Feign clients you may see initialization errors when starting your application.
-To work around this problem you can use an `ObjectProvider` when autowiring your client.
-
-[source,java,indent=0]
----
-@Autowired
-ObjectProvider<TestFeginClient> testFeginClient;
