# Abstract class encapsulating common logic for finding jobs (builds) that are related to the Secure products
# SAST, DAST, Dependency Scanning, Container Scanning and License Management, Coverage Fuzzing

# Arguments:

#     pipeline:              required, only jobs for the specified pipeline will be found
#     job_types:             required, array of job types that should be returned, defaults to all job types
