Pull Request Overview

This PR updates the enable-autogen target to automatically generate all serviceapi resources instead of relying on a hardcoded list.

• Replaces the hardcoded resource list with a dynamic loop that scans the internal/serviceapi directory
• Adjusts the sed substitution order in the add-lines target and runs goimports after modifications

Comments suppressed due to low confidence (2)

Makefile:216

• The sed substitution order was changed from inserting the added text after the marker to before it. Please confirm that this reversal is intentional, as it could affect the order in which resources are defined.

sed 's/${find}/${add}${find}/' "${filename}" > "file.tmp"

Makefile:203

• Verify that the newline escape sequence (\n) in the 'add' argument behaves as expected across environments. If it does not produce the intended result, consider adjusting the syntax or approach.

$(foreach resource,$(resources),make add-lines filename=${filename} find="project.Resource," add="$(resource).Resource,\n";)
