Installation Guide
• Download the JAR files from the official SL4J page

JAR file to your project.
• If you are using Spring Framework, then add the
dependency to the POM file of your project:
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
<version>1.0.4</version>

PMD
• PMD scans Java source code and looks for potential
problems
• Possible bugs - empty try/catch/finally/switch statements
• Dead code - unused local variables, parameters and private
methods
• Suboptimal code - wasteful String/StringBuffer usage
• Overcomplicated expressions - unnecessary if statements,
for loops that could be while loops
• Duplicate code - copied/pasted code means copied/pasted
bugs
