Cannot use MockWebServer with Junit 5? class file for org.junit.rules.ExternalResource not found

[jasonlo87]

Following all the internet wisdom and guides I'm unable to get MockWebServer to play nice w/ Junit 5.

What is the recipe for getting this to work correctly without and error like this?
final var mockUrl = this.mockWebServer.url("/").toString();
^
class file for org.junit.rules.ExternalResource not found

}

OkHttp 5 alpha has a junit 5 module.

This is what fixed it for me:

        <dependency>
            <groupId>com.squareup.okhttp3</groupId>
            <artifactId>mockwebserver3-junit5</artifactId>
            <version>5.0.0-alpha.11</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>com.squareup.okhttp3</groupId>
            <artifactId>okhttp</artifactId>
            <version>5.0.0-alpha.11</version>
            <scope>test</scope>
        </dependency>

Be sure you don't have any JUnit 4 dependencies lying around.

Huh ok this worked; thought I had tried that combo but something must've gotten lost in the sauce.

Using these dependencies my test now runs without error, thanks!
