WebClient not resolving

Question

In order to utilise the new WebClient API, I've included spring-webflux in my Intellij project.

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-web'
    compile 'org.springframework.boot:spring-boot-starter-webflux'
//    compile group: 'org.springframework', name: 'spring-webflux', version: '5.2.7.RELEASE'

    testImplementation('org.springframework.boot:spring-boot-starter-test') {
        exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
    }
}

However, WebClient remains unresolved:

C:\Users\tobia\Documents\spring-app\service\Service.java:25: error: cannot find symbol
        System.out.println(WebClient.Builder());
                           ^
  symbol:   variable WebClient
  location: class Service

The dependency itself seems to have resolved, as webflux is now in my "external libraries" list:

Does anybody have any idea why WebClient remains unresolved?

I've tried all 4 of these dependency declerations, and none work:

    compile 'org.springframework.boot:spring-boot-starter-webflux'
    compile group: 'org.springframework', name: 'spring-webflux', version: '5.2.7.RELEASE'
    implementation 'org.springframework.boot:spring-boot-starter-webflux'
    implementation group: 'org.springframework', name: 'spring-webflux', version: '5.2.7.RELEASE'

Try the second one it works for me [link](https://mvnrepository.com/artifact/org.springframework/spring-webflux/5.2.7.RELEASE). — chriptus13, Jun 19 '20 at 23:46

Your build.gradle is missing this dependency:

compile group: 'org.springframework', name: 'spring-webflux', version: '5.2.7.RELEASE'

Proof of working:

Make sure to reimport the dependencies.

The sample code for WebClient should look like this:

        WebClient client3 = WebClient
                .builder()
                .baseUrl("http://localhost:8080")
                .defaultCookie("cookieKey", "cookieValue")
                .defaultHeader(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_JSON_VALUE)
                .defaultUriVariables(Collections.singletonMap("url", "http://localhost:8080"))
                .build();

Notice that it's WebClient.builder() and not WebClient.Builder(), it looks like you have a typo in the method name, replace Builder() with builder() and it should work.

WebClient.Builder is an Interface, therefore this code is not valid:

System.out.println(WebClient.Builder());

It's a syntax issue with you code that has nothing to do with Gradle, dependencies or IntelliJ IDEA.

This doesn't work, I tried it (which is why it was commented out) – Tobi Akinyemi Jun 20 '20 at 00:13
Please see the updated answer showing that it works fine. – CrazyCoder Jun 20 '20 at 00:56
I had to invalidate my caches, for some reason. – Tobi Akinyemi Jun 20 '20 at 01:02

It wasn't. I didnt change any code, and after the refresh, it started resolving. Also I spelt it right. `WebClient` was the issue - not `Builder`. However, you are right in saying the `builder()` method is lowercase, while the class is uppercase – Tobi Akinyemi Jun 20 '20 at 01:02
Can you clarify equivalent pom.xml setting ? I don't use gradle – vikramvi Sep 01 '22 at 08:28

I had the same issue too, and I am using this dependency:

implementation 'org.springframework.boot:spring-boot-starter-webflux'

I also had to invalidate IntelliJ caches at File > Invalidate Caches
