Wikidata-Toolkit: NoSuchMethodError when following FetchOnlineDataExample

I am using exactly the code from FetchOnlineDataExample.java (from here) and nothing else:

public static void main(String[] args) {
    WikibaseDataFetcher wbdf = new WikibaseDataFetcher(
        BasicApiConnection.getWikidataApiConnection(),
        Datamodel.SITE_WIKIDATA);
    try {
        EntityDocument q42 = wbdf.getEntityDocument("Q42");
        System.out.println(q42);
    } catch (MediaWikiApiErrorException | IOException e) {
        e.printStackTrace();
    }
}

And get this error:

Exception in thread "main" java.lang.NoSuchMethodError: 'okhttp3.RequestBody okhttp3.RequestBody.create(java.lang.String, okhttp3.MediaType)'
	at org.wikidata.wdtk.wikibaseapi.ApiConnection.sendRequest(ApiConnection.java:396)

	at org.wikidata.wdtk.wikibaseapi.WikibaseDataFetcher.getEntityDocument(WikibaseDataFetcher.java:138)

I have this in my pom.xml:

<!-- https://mvnrepository.com/artifact/org.wikidata.wdtk/wdtk-wikibaseapi -->
<dependency>
   <groupId>org.wikidata.wdtk</groupId>
   <artifactId>wdtk-wikibaseapi</artifactId>

@wetneb Aren’t we missing okhttp 4.x dependency in wikibaseapi module? It could spare downstream projects of the need to declare the dependency in their own POM.

Also adding com.squareup.okhttp3:okhttp:4.2.2 seems to work! I hadn’t tried to add both okhttp-urlconnection and okhttp next to wdtk-wikibaseapi. Thanks!

@Lhaaits I will have to test this on my own app

@wetneb Mockwebserver alternative is a lot of work. Merging #694 makes it harder, because junit5 upgrade would have to be reapplied after it. I had to give my attention to two other opensource projects, so I am only getting around to this now.

My solution for now is to have a public class FixedBasicApiConnection extends BasicApiConnection that overrides sendRequest() and passes the parameters in swapped order to RequestBody.create(), then it works. If this is actually a general bug and not something local for me, I’d be happy to make a PR that swaps the parameters in ApiConnection.

The pom.xml file in this repository is for the development version of WDTK, it is normal that versions of WDTK released in the past use other versions of this dependency. So the issue probably comes from somewhere else…
