Apache camel 无法使用'；jsonpath'；在Apache Karaf中使用Apache Camel

我无法在Apache Karaf中激活以下路由

from("file:/home/data/test?delete=true")
        //See https://github.com/jayway/JsonPath
        .split().jsonpath("$.[*]") //get all the array elements
            .setHeader("targetport").jsonpath("$.targetport") //Set the value of target port in header
                .transform().jsonpath("$.payload") //Content Filter EIP
                    //.toF("netty4:tcp://%s:%s?sync=false&workerCount=1&encoding=UTF-8&&encoders=#bypass-message-encoder", , );
                    .toD("netty4:tcp://1.1.1.1:${in.header[targetport]}?sync=false&workerCount=1&encoding=UTF-8&&encoders=#bypass-message-encoder");

错误：

我也尝试过ApacheCamel 2.16.1。同样的错误

我对类似错误的搜索结果如下，但似乎没有任何一个有帮助

您是否安装了所需的功能？在Karaf中查看时，您是否看到已安装的功能和捆绑包？是的，我检查了两次。你们是如何在卡拉夫经营骆驼的（如你们是如何使它自举的）？

Apache Karaf: 4.0.3

Commands Issued:

 - feature:repo-add camel 2.15.2
