WriteProperties (Gradle API 7.6.3)

Package org.gradle.api.tasks

## Class WriteProperties

- java.lang.Object
- - org.gradle.api.internal.AbstractTask
  - - org.gradle.api.DefaultTask
    - - org.gradle.api.tasks.WriteProperties

- All Implemented Interfaces:
    `java.lang.Comparable<Task>`, `org.gradle.api.internal.DynamicObjectAware`, `org.gradle.api.internal.TaskInternal`, `ExtensionAware`, `Task`, `Configurable<Task>`

      @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
  See Also:
    `Properties.store(OutputStream, String)`

    - #### getProperties

          @Input
          public java.util.Map<java.lang.String,​java.lang.String> getProperties()

      Returns an immutable view of properties to be written to the properties file.
      Since:
        3.3

    - #### setProperties

          public void setProperties​(java.util.Map<java.lang.String,​java.lang.Object> properties)

      Sets all properties to be written to the properties file replacing any existing properties.
      See Also:
        `properties(Map)`, `property(String, Object)`

    - #### property

          public void property​(java.lang.String name,
                               java.lang.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
      Since:
        3.4

    - #### properties

          public void properties​(java.util.Map<java.lang.String,​java.lang.Object> properties)

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

      Parameters:
        `properties` - Properties to be added
      Since:
        3.4
