Question

初始化Java程序时，我得到以下错误堆栈跟踪：

Exception in thread "main" java.lang.VerifyError: class com.fasterxml.jackson.module.scala.ser.ScalaIteratorSerializer overrides final method withResolved.(Lcom/fasterxml/jackson/databind/BeanProperty;Lcom/fasterxml/jackson/databind/jsontype/TypeSerializer;Lcom/fasterxml/jackson/databind/JsonSerializer;)Lcom/fasterxml/jackson/databind/ser/std/AsArraySerializerBase;

无法理解此错误的原因是什么。它可能与我在Maven项目中使用的库之间的冲突有关吗？

以防万一我提供文件pom.xml：

添加以下依赖项将解决问题。

    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-databind</artifactId>
        <version>2.6.7.1</version>
    </dependency>

    <dependency>
        <groupId>com.fasterxml.jackson.module</groupId>
        <artifactId>jackson-module-scala_2.10</artifactId>
        <version>2.6.7.1</version>
    </dependency>
