Sylwester Lachiewicz commented on MNG-6495:
-------------------------------------------

Looks like we need to update doc here: [ModelBuildingRequest:298|https://gitbox.apache.org/repos/asf?p=maven.git;a=blob;f=maven-model-builder/src/main/java/org/apache/maven/model/building/ModelBuildingRequest.java;h=bc6e71bee21c2c97538a89bad931dc34ad1574cc;hb=HEAD#l298] ?

> Got this exception stacktrace while writing some of my own code today:

> Exception in thread "main" java.lang.NullPointerException: request.modelResolver cannot be null (parent POM com.google.guava:guava-parent:26.0-jre and POM com.google.guava:guava:[unknown-version])
> 	at org.apache.commons.lang3.Validate.notNull(Validate.java:225)

> No big deal except that the JavaDoc at [ModelBuildingRequest|http://maven.apache.org/ref/3.5.4/maven-model-builder/apidocs/org/apache/maven/model/building/ModelBuildingRequest.html] says "The model resolver to use, may be null."
> Not sure whether to update the docs or the code here.
