我看到两种可能性:

1. 您没有jira连接器jar作为库.该错误表明xml解析器无法识别jira:config元素，该元素位于jira连接器xsd中，而js连接器jar中.
2. 您没有在XML顶部声明jira命名空间.

您可以通过以下任意一种方式包括连接器:

You can include the connector in any of these ways:

1. 在Studio中安装(我从不厌倦这种方法)，您的调色板中应该有JIRA连接器，并且能够将其放入流程中并进行配置.

2. 此处，然后在您的配置中包括JIRA连接器名称空间:

1. Install it in Studio (I've never tired this approach) and you should have JIRA connector in your pallette and be able to drop it in a flow and configure it.

2. Here you will find the latest release for JIRA connector. Add the jar file as a library in studio as shown here then include JIRA connector namespace in your configuration:

<mule xmlns="http://www.mulesoft.org/schema/mule/core" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"      xmlns:jira="http://www.mulesoft.org/schema/mule/jira"
  xsi:schemaLocation="
    http://www.mulesoft.org/schema/mule/core http://www.mulesoft.org/schema/mule/core/current/mule.xsd
    http://www.mulesoft.org/schema/mule/jira http://www.mulesoft.org/schema/mule/jira/current/mule-jira.xsd">

及以下内容按照您的问题来编写流程.

and below write your flow like in your question.
