如何避免Maven Shade插件包含来自'test-jar'类型的传递依赖项？

问题描述 投票：2回答：1

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，spark-core_2.11:2.4.0，spark-catalyst_2.11:2.4.0用于单元测试。如您所见，这些Spark模块全部是内部使用jackson-databind:2.6.7.1的2.4.0版。请参考下面提供的POM：

现在，当我构建spark-module时，当Maven阴影插件启动时，它包含jackson-databind:2.6.7.1而不是2.8.11（我认为它会来自core-module）。当我在test-jar依赖项中添加以下排除项时，它会正确捆绑2.8.11版本的JAR，但是由于排除了依赖项，这使我的测试失败了：

<exclusions>
    <exclusion>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>*</artifactId>
    </exclusion>
    <exclusion>
        <groupId>com.fasterxml.jackson.module</groupId>
        <artifactId>*</artifactId>
    </exclusion>
    <exclusion>
        <groupId>org.javassist</groupId>
        <artifactId>*</artifactId>
    </exclusion>
</exclusions>

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？

要控制jackson-databind的版本，请在<dependencyManagement>部分中添加一个条目，您可以在其中指定所需的版本。这将覆盖所有传递定义，并且比各种排除方法更容易处理。

因此，在第一步中，您可以尝试将其设置为<version>2.8.11</version>，然后尝试测试是否可行。如果不是，那么您需要找出一个既适用于core-module中的应用程序又适用于您的测试的“中间版本”。
