@Incubating @CacheableTask public class WriteProperties extends DefaultTask
Writes a Properties in a way that the results can be expected to be reproducible.

There are a number of differences compared to how properties are stored:

  • no timestamp comment is generated at the beginning of the file
  • the lines in the resulting files are separated by a pre-set separator (defaults to '\n') instead of the system default line separator
  • the properties are sorted alphabetically

Like with Properties, Unicode characters are escaped when using the default Latin-1 (ISO-8559-1) encoding.

Since:
3.3

    • property

      @Incubating public void property(String name, Object value)
      Adds a property to be written to the properties file.

      A property's value will be coerced to a String with String#valueOf(Object) or a Callable returning a value to be coerced into a String.

      Values are not allowed to be null.

      Parameters:
      name - Name of the property
      value - Value of the property

      @Incubating public void properties(Map<String,Object> properties)
      Adds multiple properties to be written to the properties file.

      This is a convenience method for calling property(String, Object) multiple times.

      Parameters:
      properties - Properties to be added
