Giovanni van der Schelde commented on MNG-7707:
-----------------------------------------------
After some debugging the directory seems to be created in the
[{{ConsumerPomArtifactTransformer#injectTransformedArtifacts()}}|https://github.com/apache/maven/blob/master/maven-core/src/main/java/org/apache/maven/internal/transformation/ConsumerPomArtifactTransformer.java#L64].
The {{project.getBuild().getDirectory()}} is filled with the value
{{${project.basedir}/target}}.
[~cstamas], was it your intention to create a temporary consumer pom ([line
70|https://github.com/apache/maven/blob/master/maven-core/src/main/java/org/apache/maven/internal/transformation/ConsumerPomArtifactTransformer.java#L70]),
or should it not even inject the transformed artifacts as there is no project
to build?
> ${project.basedir} folder creation when running plugin
> ------------------------------------------------------
>
> Key: MNG-7707
> URL: https://issues.apache.org/jira/browse/MNG-7707
> Project: Maven
> Issue Type: Bug
> Affects Versions: 4.0.0-alpha-4, 4.0.0-alpha-5
> Reporter: Giovanni van der Schelde
> Priority: Minor
>
> When running {{mvn archetype:generate}} in a directory without providing a
> valid {{{}pom.xml{}}}, a directory named {{{}$\{project.basedir{}}}} is
> created in the folder you execute the command from.
> I could be wrong but the reason which leads me to believe it to be in
> maven-core is that when I put a breakpoint at the start of the {{exectute()}}
> method in the [generate
> mojo|https://github.com/apache/maven-archetype/blob/master/maven-archetype-plugin/src/main/java/org/apache/maven/archetype/mojos/CreateProjectFromArchetypeMojo.java#L177]
> the folder is already created.
