Lenny Primak commented on MNG-7745:
-----------------------------------
Easy. Run the following maven command *outside* of any maven project. The
result will be the same:
{code:java}
mvn dependency:copy -Dartifact=org.postgresql:postgresql:LATEST:jar
-Dproject.basedir=. -DoutputDirectory=xxx -DoverWrite=false {code}
> NPE when .mvn doesn't exist
> ---------------------------
>
> Key: MNG-7745
> URL: https://issues.apache.org/jira/browse/MNG-7745
> Project: Maven
> Issue Type: Bug
> Components: Core
> Affects Versions: 4.0.0-alpha-4, 4.0.0-alpha-5
> Environment: Any
> Reporter: Lenny Primak
> Assignee: Guillaume Nodet
> Priority: Minor
>
> When maven is executed without a .mvn directory, an NPE appears every time.
> This doesn't seem to affect anything but does pollute the logs:
> {code:java}
> Failed to notify spy org.apache.maven.ReactorReader$ReactorReaderSpy: Cannot
> invoke "java.io.File.toPath()" because the return value of
> "org.apache.maven.project.MavenProject.getFile()" is null {code}
