Elliotte Rusty Harold created MNG-6495:
------------------------------------------
Summary: ModelResolver cannot be null
Key: MNG-6495
URL: https://issues.apache.org/jira/browse/MNG-6495
Project: Maven
Issue Type: Bug
Components: Bootstrap & Build
Affects Versions: 3.5.4
Reporter: Elliotte Rusty Harold
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)

org.apache.maven.model.building.DefaultModelBuilder.readParentExternally(DefaultModelBuilder.java:1046)

org.apache.maven.model.building.DefaultModelBuilder.readParent(DefaultModelBuilder.java:830)
at
org.apache.maven.model.building.DefaultModelBuilder.build(DefaultModelBuilder.java:332)
at
com.google.cloud.tools.opensource.dependencies.MetadataExplorer.main(MetadataExplorer.java:50)
No big deal except that the JavaDoc at
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.
