next :
_/build-dars
and compare the project ids using api:

 daml damlc inspect-dar --json ./services/canton-participant/scripts/dars/eleox-0.0.1.dar | jq '.main_package_id'
"6ace966b605bb0965797d0ed4afc8972015f4d885d1fe8314fefbe0280405ce1"
 daml damlc inspect-dar --json ./services/canton-participant/scripts/dars/eleox-0.0.1.dar | jq '.main_package_id'
