Issues are displayed, one for each warning or error. Each issue includes the line number, severity, and a brief description of the issue. It also includes the rule name, which you can use to look up a more detailed description of the issue. See “Aura Component Validation Rules” for the rules applied by Lightning code validations, as well as possible resolutions and options for further reading.

Your mission is to review each issue, examine the code in question, and to revise it to eliminate all of the genuine problems.

While no automated tool is perfect, we expect that most errors and warnings generated by Lightning code validations will point to genuine issues in your code, which you should plan to fix as soon as you can.
