Migrate from org.joda.time.format.DateTimeFormatterBuilder to Java Time

Joda-Time DateTimeFormatterBuilder migrates to java.time DateTimeFormatterBuilder.

It's the same concept, a builder of the formatter.

Although, most of the methods have a different signature and some even have no equivalent in java.time

Those methods have no equivalent:

  • canBuildFormatter
  • canBuildPrinter
  • canBuildParser

Find some examples below:

Before 
    DateTimeFormatterBuilder dtfb = new DateTimeFormatterBuilder();
    DateTimeFormatterBuilder appendSecondOfDay = dtfb.appendSecondOfDay(intArg);
After 
    java.time.format.DateTimeFormatterBuilder dtfb = new java.time.format.DateTimeFormatterBuilder();
    java.time.format.DateTimeFormatterBuilder appendSecondOfDay = dtfb.appendValue(ChronoField.SECOND_OF_DAY, intArg);

    Searches for a append* method called and provides fixes to migrate to a java.time equivalent.
    This recipe is designed to match on broken code. This method originally was called by joda DateTimeFormatterBuilder type,
    however this object type should first be migrated to java.time.format.DateTimeFormatterBuilder using the other migration recipes.
    This recipe will then match on the broken code, and the fixes in this recipe will allow the completion of the migration.
