How do I ignore duplicate codes in Sonarqube?
Ignore Duplications You can prevent some files from being checked for duplications. To do so, go to Project Settings > General Settings > Analysis Scope > Duplications and set the Duplication Exclusions property. See the Patterns section for more details on the syntax.
How does SonarQube calculate duplicated code?
To help you detect and eliminate duplication, SonarQube uses its own copy/paste detection engine, which can detect duplications:
- Within a source file.
- Across multiple files in a project.
- Across modules of a project.
- Across multiple projects.
What to do about code duplication in Java?
SonarQube indicates that SynchronizedStatementTreeImpl.java, SwitchStatementTreeImpl.java and ParenthesizedTreeImpl.java have the same code block duplicated across them. The simplest solution for the problem at hand is to define a super class, and define the duplicated blocks as code within its methods.
How to avoid code duplication in abstract class?
ClassD extends abstract ClassE which extends abstract ClassF which extends abstract ClassC. where ClassA and ClassD have a set of identical properties, getters, & setters. I want to avoid that code duplication (properties,getters,setters).
When to use generic code to avoid duplication?
As long as T can get expanded into a class that will compile, the generic code will build. I call it generic to indicate that it’s not hardcoded to any one type, but rather that the type is left until the template is instantiated. Here, we have a class member function that has a small code block used very similarly four times.
Is there a way to fix duplicate code?
Over time, the duplication might become varied slightly such that it’s not even clear which version is the correct version. Ideally, the duplicated code can be simply extracted to one function to be called from multiple places. However, sometimes fixing the duplication is not so simple or obvious.
