Swift Changes

The Swift parser now forwards syntax errors as usual processing errors. Before it just logged any errors and tried to move on, resulting in an incomplete AST with error nodes. As part of this change, the grammar has been slightly improved around macro declarations, generic parameters and parameter packs.
This means that PMD might fail now on Swift files with processing errors, when it previously ran without obvious problems. The Swift module in PMD now behaves like other modules in regard to error handling.

Updated PMD Designer

This PMD release ships a new version of the pmd-designer. For the changes, see PMD Designer Changelog (7.19.3).

🌟️ New and Changed Rules

New Rules

  • The new Java rule WrongTestAnnotation detects when test annotations from the wrong testing framework (JUnit 4, JUnit Jupiter, or TestNG) are used in your code, preventing tests from being silently skipped due to framework mismatches. This helps avoid the silent failure where tests compile but don’t execute because the test runner doesn’t recognize the annotation.
  • The new Java rule AssertEqualsArgumentOrder detects assertions where the expected and actual arguments were swapped. This helps find assertions that are producing a confusing error message when they fail.
  • The new Kotlin rule LocalVariableShadowsParameter detects local variable declarations that use the same name as a parameter of the enclosing function. This shadows the parameter and may lead to confusion about which value is used.
  • The new Apex rule InvocableClassNoArgConstructor detects classes that use @InvocableVariable properties, but that don’t provide a no-arg constructor. Without such a constructor, runtime exception occur when Salesforce Flow tries to instantiate such classes.
