Description

Consider the below script, SnakeYaml.groovy

 

@Grab(group = 'org.yaml', module = 'snakeyaml', version = '1.28')

import org.yaml.snakeyaml.DumperOptions
import org.yaml.snakeyaml.Yaml

def object = [
 array: [1, 2]
]
DumperOptions dumperOptions = new DumperOptions(defaultFlowStyle: DumperOptions.FlowStyle.BLOCK,
 indent: 2, width: 200, indentWithIndicator: true, indicatorIndent: 2)
println(new Yaml(dumperOptions).dump(object))

 

 

When running the below script as groovy SnakeYaml.groovy in groovy 3.x, the below exception is thrown:

Caught: groovy.lang.MissingPropertyException: No such property: indentWithIndicator for class: org.yaml.snakeyaml.DumperOptions
groovy.lang.MissingPropertyException: No such property: indentWithIndicator for class: org.yaml.snakeyaml.DumperOptions
	at SnakeYaml.run(SnakeYaml.groovy:9)

	at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)

 

The same script runs fine in groovy 2.5.x and returns the below output as expected:

array:
 - 1
 - 2
