Spring BootDuplication
Intro
- For duplication, we look at places in code where there are six or more lines of code that are exactly the same.
- Before duplication is calculated, the code is cleaned to remove empty lines, comments, and frequently duplicated constructs such as imports.
- You should aim at having as little as possible (<5%) of duplicated code as high-level of duplication can lead to maintenance difficulties, poor factoring, and logical contradictions.
Duplication Overall
- 4% duplication:
- 82,049 cleaned lines of cleaned code (without empty lines, comments, and frequently duplicated constructs such as imports)
- 3,493 duplicated lines
- 179 duplicates
