Installation
On this page
For the most part, SonarQube for IDE can be installed directly from your IDE's Marketplace. Offline installations are also possible and previous versions are available if needed.
Instructions
Installation is usually completed via the IDE, directly from the JetBrains Marketplace. In IntelliJ, go to Settings > Plugins; search for SonarQube for IDE in the Marketplace tab. Select Install. When complete, you must select Restart IDE and confirm the Restart to activate the new plugin.
If SonarQube for IDE does not appear in the Marketplace when searching from within the IDE, it means that your IDE is not supported.
First taste of SonarQube for IDE
Now that you have SonarQube for IDE installed, open or create a new project containing source files in a programming language SonarQube for IDE can analyze out of the box. See the Rules page for languages that work with your IDE.
Then check out the Investigating issues page for details about how to recognize issues found in your code.
JetBrains flavor: IntelliJ IDEA
Language: Java
import java.util.ArrayList;
import java.util.List;
public class Main {
public static void main(String[] args) {
List<String> texts = new ArrayList<String>();
if (texts != null) {
texts.add("Hello World!");
}
}
}This code sample should raise two issues:
- Remove this expression which always evaluates to “true”
- It has three secondary locations explaining the flows
- Replace the type specification in this constructor call with the diamond operator (“<>”)
- It has a quick fix
JetBrains flavor: CLion
Language: C++
#include <string>
typedef int Integer;
size_t get_size(std::string& s) {
return s.size();
}This code sample should raise two issues:
- “using” is preferred to “typedef” for type aliasing
- It has a quick-fix
- Make the type of this parameter a reference-to-const
CLion offers multiple ways of setting up a C++ project using different build tools and allows the use of different compilers. Note that you may need to install dependencies on your machine beforehand.
JetBrains flavor: Rider
Language: C#
public class Math {
int Pow(int num, int exponent)
{
return num * Pow(num, exponent - 1);
}
}This code sample should raise one issue:
- The method is in an indefinite loop
JetBrains flavor: WebStorm
Language: TypeScript
const a = NaN;
if (a === NaN) {
console.log("a is not a number");
}This code sample should raise one issue:
- The code inside the condition is dead code
Rider
There are specific requirements for Rider which are documented inside the SonarQube for IDE in Rider collapsible on the Scan my project page.
