Apache Commons LangDuplication
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
- 11% duplication:
- 21,820 cleaned lines of cleaned code (without empty lines, comments, and frequently duplicated constructs such as imports)
- 2,483 duplicated lines
- 86 duplicates
