我正在研究一个具有模块间依赖性的多模块Maven项目。例如：项目的一个模块，例如spark-module依赖于同一项目的另一个模块（例如core-module）。

core-module依赖于jackson-datatype-jsr310:2.8.11，在spark-module中，我从Apache Spark项目添加了测试罐-spark-sql_2.11:2.4.0，{{1} }，spark-core_2.11:2.4.0用于单元测试。如您所见，这些Spark模块都是2.4.0版，它们内部使用spark-catalyst_2.11:2.4.0。请参考下面提供的POM：

jackson-databind:2.6.7.1

test-jar

也许我在处理依赖项的方式上做错了。所以，请您帮我了解在这里应该做什么？
