NoSuchMethodError: 'okhttp3.RequestBody okhttp3.RequestBody.create(java.lang.String, okhttp3.MediaType)' about web3j

I don't have the square dependency and it works. Which web3j version are you using? Could you paste the imports?

Encountered the same problem！

Hey @saugion, it's in the desc of the issue, isn't it? 🤔

        <!-- Web3j - blockchain -->
        <dependency>
            <groupId>org.web3j</groupId>
            <artifactId>core</artifactId>
            <version>4.9.7</version>
        </dependency>

I'm sorry @bofomike you're right, i didn't notice it. Could you try to use the last version, https://mvnrepository.com/artifact/org.web3j/core/4.10.3?

I did and it's not working neither.

the square dependency should not be needed as already included in the web3j library. I have the feeling that one of the other libraries declared in the pom have another dependency with a different version, and this causes the issue. Could you provide a reproducible example, a sample project that I can clone? Thanks

Hey, I've updated spring version from 2.6.2 to 3.0.0 and it's all good 👍
That was tricky because it's an old micro-service I'm updating, but it's good in a long run anyway.
No need for okhttp3 dependency at all now 👌
I'm closing this.
Thanks!
