Static Analysis
Static analysis or also known as Static Code Analysis is a process to analyze the source code of a software without running the software itself. Static Analysis are generally used by developers as part of the development and component testing process.
Benefits...
Detecting the possible bugs on your code (crash, memory leak, stack overflow, buffer overflow, etc),
Find any vulnerabilities in the corner of your applications (clumsy developer miss),
Finding possible wrong logic and any bad practice on your project,
Finding areas of the code that may need more testing or deeper review,
Benefits… (cont)
Finding duplicate code which is could be moved into another methods to reduce code complexity,
Identifying design issues such as Cyclomatic Complexity and helping reduce the code complexity improve maintainability,
Identifying potential software quality issues before the code moves to production.

Setting up SQ Server. (Mac)
$ brew install sonar
Setting up SQ Server. (Linux)# download SonarQube
$ wget http://dist.sonar.codehaus.org/sonarqube-5.X.zip
# Unzip and move file into /opt/
$ unzip sonarqube-5.X.zip$ mv sonarqube-5.X /opt/sonar
Setting up Databases (MySQL)$ mysql -u root -p
CREATE DATABASE sonar CHARACTER SET utf8 COLLATE utf8_general_ci;CREATE USER 'sonar' IDENTIFIED BY 'sonar';GRANT ALL ON sonar.* TO 'sonar'@'%' IDENTIFIED BY 'sonar';GRANT ALL ON sonar.* TO 'sonar'@'localhost' IDENTIFIED BY 'sonar';FLUSH PRIVILEGES;
Connect SQ to Databases
Open /opt/sonar/conf/sonar.properties
sonar.jdbc.username=sonarsonar.jdbc.password=sonar
sonar.jdbc.url=jdbc:mysql://localhost:3306/sonar?useUnicode=true&characterEncoding=utf8&rewriteBatchedStatements=true&useConfigs=maxPerformance
Setting up web server.
Open /opt/sonar/conf/sonar.properties
sonar.web.host=127.0.0.1sonar.web.context=/sonarsonar.web.port=9000
Starting sonar...
$ sonar start
Or
$ sudo sonar start
Analyzing
Maven Projects

Maven
Setting up Maven.
Edit the settings.xml file, located in $MAVEN_HOME/conf or ~/.m2
<settings> <pluginGroups><pluginGroup>org.sonarsource.scanner.maven</pluginGroup></pluginGroups> <profiles> <profile> <id>sonar</id> <activation> <activeByDefault>true</activeByDefault> </activation> <properties> <!-- Optional URL to server. Default value is http://localhost:9000 --> <sonar.host.url>http://myserver:9000</sonar.host.url> </properties> </profile> </profiles></settings>
Analyzing Maven Projects
$ mvn clean verify sonar:sonar
## In some cases:
$ mvn clean install$ mvn sonar:sonar
Gradle
Setting up Gradle Projects
Add this line into build.gradleplugins { id "org.sonarqube" version "1.2" }
apply plugin: "org.sonarqube"
sonarqube {
properties {
property "sonar.host.url", "http://myserver:9000"
property "sonar.sourceEncoding", "UTF-8"
property "sonar.language", "java"
property "sonar.profile", "Android Lint"
property "sonar.projectKey","PROJECT-KEY"
property "sonar.projectName","PROJECT_NAME"
property "sonar.projectVersion","VERSION"
property "sonar.java.source", "1.7"
property "sonar.sources", "./"
}
}
Analyzing Gradle Project
$ ./gradlew clean check sonarqube
