The asf-staging branch is only used for storing the generated static website for previewing proposed changes to the website.
The preview site is at https://jena.staged.apache.org
The javadoc is stored on a separate branch javadoc but is also included into the staging site.
When submitting patches, apply them to the main branch instead of the asf-site branch. Any PR based on a branch off of main will automatically be built and staged here.
