在添加jasper-report依赖项的maven项目中构建问题

Question

在我基于Spring的Camel maven项目中，为Jasper报告添加了以下依赖项，我在项目构建时遇到了问题。

Jasper Dependency：

<dependency>
        <groupId>net.sf.jasperreports</groupId>
        <artifactId>jasperreports</artifactId>
        <version>6.0.4</version>
   </dependency> 

以下是异常的堆栈跟踪：

我认为jasper报告的支持jackson依赖项与之前的依赖项存在冲突。

以下是jasper报告的pom.xml的依赖关系层次结构。

但是，如果我删除了jasper报告的依赖关系，那么它工作正常。

我无法完全解决这个问题。

您的问题出错了，更改了答案

您的方法所在的类是jackson.core 2.4.3的一部分。如果明确包含它，它应该可以解决您的问题。

添加以下依赖项：

<dependency> 
    <groupId>com.fasterxml.jackson.core</groupId> 
    <artifactId>jackson-core</artifactId> 
    <version>2.4.3</version> 
</dependency>
<dependency> 
    <groupId>com.fasterxml.jackson.core</groupId> 
    <artifactId>jackson-annotations</artifactId> 
    <version>2.4.3</version> 
</dependency>
