I clone code from the project repository and import it into IDEA for build, but it reports an error as follows:

` Could not determine the dependencies of task ':sponge :compileJava'.

Could not resolve all task dependencies for configuration ':sponge :compileClasspath'.
Could not resolve project :GriefDefenderAPI.
