DuplicateStringLiteralInspection

java/java-impl/resources/inspectionDescriptions/DuplicateStringLiteralInspection.html

2025.3-rc-2684 B
Original Source

Reports string literals that are replicated unchanged throughout the project. Two quick-fixes are provided. One to introduce a constant for a duplicated string and use it throughout the project, and one to show the location of all the duplicates of a particular string literal.

Example:

class C1 { String CONST1 = "duplicate string"; }
  class C2 { String CONST2 = "duplicate string"; }

Configure the inspection:

  • Use the Min string length field to set the minimal string length required to detect duplicates.
  • Use the Ignore @PropertyKey expressions option to ignore strings passed as arguments to methods annotated with org.jetbrains.annotations.PropertyKey.
