> RemoteCatalogArchetypeDataSource.getArchetypeCatalog calls [RemoteCatalogArchetypeDataSource.getMirror|https://github.com/apache/maven-archetype/blob/maven-archetype-3.1.2/archetype-common/src/main/java/org/apache/maven/archetype/source/RemoteCatalogArchetypeDataSource.java#L86].
> RemoteCatalogArchetypeDataSource.getMirror calls legacySupport.getSession, then [invokes getRequest on the returned value|https://github.com/apache/maven-archetype/blob/maven-archetype-3.1.2/archetype-common/src/main/java/org/apache/maven/archetype/source/RemoteCatalogArchetypeDataSource.java#L299] with no null check.
> When the legacySupport session is null, this results in a NullPointerException.
> The fix is to add a null check before calling session.getRequest.
