组件 camel-jsonpath 添加到 pom 文件后出现错误 [英] Component camel-jsonpath gives error after adding to pom file

问题描述

在一个干净的 Camel 项目中，我添加了以下依赖项:

In a clean Camel project I add the following dependency:

<dependency>
  <groupId>org.apache.camel</groupId>
  <artifactId>camel-jsonpath</artifactId>
  <version>2.16.1</version>       
</dependency>

当我运行项目时，出现以下错误.如果我删除该依赖项，它将起作用.我在两个不同的项目上试过这个，同样的事情发生了.为了使 jsonpath 工作，还必须将其他任何内容添加到 pom 中吗?好像在抱怨ASM?

When I run the project I get the below error. If I remove that dependency it works. I have tried this on two different projects and the same happens. Anything else that has to be added to the pom for jsonpath to work? It seems to complain for ASM?

添加后:

<dependency>
    <groupId>org.ow2.asm</groupId>
    <artifactId>asm-commons</artifactId>
    <version>5.0.3</version>
    <scope>runtime</scope>
</dependency> 

它有效，但怀疑这是正确的方法.camel-component 应该获取所有依赖的 jars.

It worked but doubt this is the correct way. The camel-component should get all the dependent jars.

推荐答案

我在 Camel nabble 论坛上发布了这个，看来你需要添加 asm 依赖才能让它工作.

I posted this on the Camel nabble forum and indeed it seems you need to add the asm dependency to get it to work.

http://camel.465427.n5.nabble.com/Error-with-Camel-component-camel-jsonpath-td5777201.html

<dependency>
    <groupId>org.ow2.asm</groupId>
    <artifactId>asm-commons</artifactId>
    <version>5.0.3</version>
    <scope>runtime</scope>
</dependency>
