--------------------------------
Resolution: Not A Problem
> Dependency resolution difference between Maven 3 and 4
> ------------------------------------------------------
>
> Key: MNG-8581
> URL: https://issues.apache.org/jira/browse/MNG-8581
> Project: Maven
> Issue Type: Bug
> Components: Dependencies
> Affects Versions: 3.9.9, 4.0.0-rc-2
> Reporter: Maurice Zeijen
> Priority: Major
>
> h2. Problem
> I discovered a dependency resolution difference between Maven 3.9.9 and Maven
> 4.0.0-rc-2.
> When adding the dependency _io.fabric8:kubernetes-httpclient-okhttp:6.13.4_
> Maven 3 and 4 will resolve different versions of the transitive
> _com.squareup.okio:okio_ dependency.
> Resolved versions of Okio:
> Maven 3: *_1.15.0_*
> Maven 4: *_1.17.6_*
> h2. Effect
> Due to this unexpected version resolution difference my application failed
> due to an MethodNotFoundException with Maven 4 that doesn't occur with Maven
> 3.{*}{*}
> h2. Investigation
> I did a small investigation where these versions are coming from. When
> depending on _io.fabric8:kubernetes-httpclient-okhttp:6.13.4_ you get the
> following dependency path to the Okio dependency:
> * _io.fabric8:kubernetes-httpclient-okhttp:6.13.4_
> ** _com.squareup.okhttp3:okhttp:3.12.12_
> *** _com.squareup.okio:okio_
> The Okio version is defined in two places within this three and there parents.
> * The {_}io.fabric8:{_}{_}kubernetes-httpclient-okhttp{_} has the
> io.fabric8:kubernetes-client-project parent, which defines that the okio
> version should be *1.17.6*
> * The _com.squareup.okhttp3:okhttp_ has the _com.squareup.okhttp3:parent_
> project parent, which defines that the okio version should be *1.15.0*
> h2. *Reproduction*
