Sitemaps cannot be generated when DSpace CRIS is running in a Docker setup

[saschaszott]

Problem description

When executing the CLI job /dspace/bin/dspace generate-sitemaps, the sitemaps directory (configurable via sitemap.dir; defaults to ${dspace.dir}/sitemaps) is also created if it does not already exist (see GenerateSitemaps::generateSitemaps).

However, the dspace user inside the Docker container does not have permission to create a directory under /dspace. As a result, a error log message is printed when running the CLI job:

2025-10-16 21:27:34,419 ERROR unknown unknown org.dspace.app.sitemap.GenerateSitemaps @ Unable to create output directory

This issue does not occur in DSpace, but only in DSpace CRIS, due to this line of code:
