During a code review, you discover quality issues in a Java application.
You need to recommend a solution to detect quality issues including unused variables and empty catch blocks.
What should you recommend?
A. In a Maven build task, select Run PMD.
B. In an Xcode build task, select Use xcpretty from Advanced.
C. In a Gulp build task, specify a custom condition expression.
D. In a Grunt build task, select Enabled from Control Options.
Correct Answer: A
PMD is a source code analyzer. It finds common programming flaws like unused variables, empty catch blocks, unnecessary object creation, and so forth.
There is an Apache Maven PMD Plugin which allows you to automatically run the PMD code analysis tool on your project’s source code and generate a site report with its results.
Incorrect Answers:
B: xcpretty is a fast and flexible formatter for xcodebuild.
