In my springboot project, pom.xml has a dependency:

		<!-- https://mvnrepository.com/artifact/org.yaml/snakeyaml -->
		<dependency>
			<groupId>org.yaml</groupId>
			<artifactId>snakeyaml</artifactId>
			<version>1.31</version>
		</dependency>

However, it told me that Dependency 'org.yaml:snakeyaml:1.31' not found". if change to version 1.30 is okay.
But I need the version higher than 1.30 to load others dependency.
