# build stage
# Sonarqube related jobs put here for this reason:
# Here we have two jobs. code_quality_check and code_quality_report.
#
# code_quality_check will analyze the code changes between your MR and
# code repo stored in sonarqube server. The analysis result is only shown in
# the comments under this MR and won't be transferred to the server.
#
# code_quality_report will analyze and transfer both of the newly added code
# and the analysis result to the server.
#
# Put in the front to ensure that the newly merged code can be stored in
# sonarqube server ASAP, in order to avoid reporting unrelated code issues
