MapStruct v1.4.0.Beta3 Release Notes

Release Date: 2020-07-19 // almost 4 years ago

  • ✨ Enhancements

    • 👌 Improve the error message when using @Qualifier in 2 step mapping methods (#2135)
    • Strip leading underscore when in local variable names (#2142)
    • 👍 Allow @Default to overrule potentially existing parameterless default constructor. (#2150) - With this we actually changed the rules for selection a constructor. Now the following is done:
      • Constructor annotated with @Default (from any package) has highest precedence
      • If there is a single public constructor then it would be used to construct the object
      • If a parameterless constructor exists then it would be used to construct the object, and the other constructors will be ignored
    • 👌 Improve ambiguous method error description (#2156)

    🐛 Bug fixes

    • NullPointerException when using only Mapping#target in mapping inheritance (#2139)
    • Selection JAXB object factory has been compromised between 1.3.1.Final and 1.4.0Beta2 (#2145)
    • 0️⃣ Internal error in the mapping processor: java.lang.ArrayIndexOutOfBoundsException: 0 (#2149) - This was caused by using @BeanMapping(ignoreByDefault = true) in combination with @Mapping(target = "."). This is now not allowed
