Caused by: java.lang.NoSuchFieldError: okhttp3/RequestBody.Companion

[jacksierkstra]

Expected Behavior

Being able to construct a DaprClient by using new DaprClientBuilder().build().

Actual Behavior

Instead of being able to construct a new instance, the application crashes with the following stacktrace:

Steps to Reproduce the Problem

I created a very small Spring Boot application that creates a DaprClient upon starting up as a bean.

The application has the following (relevant) dependencies:

  <properties>
        <java.version>11</java.version>
        <dapr.version>1.1.0-SNAPSHOT</dapr.version>
    </properties>
<dependencies>
      <dependency>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-starter-web</artifactId>
      </dependency>
      <dependency>
          <groupId>io.dapr</groupId>
          <artifactId>dapr-sdk</artifactId>
          <version>${dapr.version}</version>
      </dependency>
      <dependency>
          <groupId>io.dapr</groupId>
          <artifactId>dapr-sdk-springboot</artifactId>
          <version>${dapr.version}</version>
      </dependency>
  </dependencies>

And I added the following configuration:

@Configuration
public class ApplicationConfiguration {

    @Bean
    public DaprClient daprClient() {
        return new DaprClientBuilder().build();
    }
}

When I start my application, it crashes. Tried with both dapr version 1.0.0 and 1.1.0-SNAPSHOT.

Release Note

RELEASE NOTE: FIX Bug in construction of HTTP client.

[artursouza]

@jacksierkstra This is a common issue when the OkHTTP version conflicts from the Dapr SDK and any of your other dependencies. You can fix this by changing the springboot version to one that uses a compatible OkHTTP version or force a compatible okHTTP version in your project by adding the following dependency:

    <dependency>
      <groupId>com.squareup.okhttp3</groupId>
      <artifactId>okhttp</artifactId>
      <version>4.9.0</version>
    </dependency>

Ok, thank you.
