The worst consequence of a big number of duplicates is a case when a software vulnerability is copied, the vulnerability may continue to exist in the copied code if the developer is not aware of such copies. Refactoring of duplicated code can improve many software metrics, such as lines of code, complexity. This may lead to shorter compilation times, lower cognitive load, less human error, and fewer forgotten or overlooked pieces of code.
...
Duplicate code lines values are shown in % (Axis Y) and distributed over time (Axis X) on the chart.
...
Calculation
Duplicated Lines (%) = Duplicated Lines / LOC * 100%,
where
Duplicated Lines - a number of duplicates
LOC - number of all code lines
RAG thresholds: Green <= 2%, Amber <=10%, Red >10%.
Data Source
Data for the metric can be collected from Sonar.
