如何避免 maven 陰影插件包含來自“test-jar”類型的傳遞依賴？

Question

我正在開發一個具有模塊間依賴關系的多模塊 Maven 項目。 例如：項目的一個模塊，比如spark-module依賴於來自同一項目的另一個模塊（比如core-module ）。

core-module依賴於jackson-datatype-jsr310:2.8.11並且在spark-module中，我添加了來自 Apache Spark 項目的測試罐 - spark-sql_2.11:2.4.0 ， spark-core_2.11:2.4.0 , spark-catalyst_2.11:2.4.0用於單元測試目的。 如您所見，這些 Spark 模塊都是 2.4.0 版本，內部使用jackson-databind:2.6.7.1 。 請參考下面提供的 POM：

現在，當我構建spark-module時，當 maven 陰影插件啟動時，它包含jackson-databind:2.6.7.1而不是 2.8.11 （我認為它來自core-module ）。 當我將以下排除項添加到test-jar依賴項時，它會正確捆綁 2.8.11 版本 JAR 但這會使我的測試失敗，因為排除了依賴項：

<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>

也許我在處理依賴項的方式上做錯了。 那么你能幫我理解這里應該做什么嗎？

Answer 1

要控制jackson-databind的版本，請在<dependencyManagement>部分添加一個條目，在該部分中指定所需的版本。 這將覆蓋所有傳遞定義，並且比各種排除更容易處理。

因此，在第一步中，您可以嘗試將其設置為<version>2.8.11</version>並嘗試您的測試是否有效。 如果沒有，那么您需要找出一個“中間版本”，它既適用於core-module中的應用程序，也適用於您的測試。
