实际上，snakeyaml 2.0没有为org.yaml.snakeyaml.constructor.SafeConstructor类提供empty-arg构造函数。
在snakeyaml 1.33中存在这样的构造函数，但已被弃用。
在snakeyaml2.0中尝试替换

import org.yaml.snakeyaml.{LoaderOptions, Yaml}
import org.yaml.snakeyaml.constructor.SafeConstructor

val safeConstructor = new SafeConstructor
val yaml = new Yaml(safeConstructor)

与

val loaderOptions = new LoaderOptions
// loaderOptions.setCodePointLimit(...)
// ...
val safeConstructor = new SafeConstructor(loaderOptions)
val yaml = new Yaml(safeConstructor)
