Activiti error:using JavaScript in .bpmn20.xml

Question

我试过在Activiti进程中那样使用JS：

<process id="test_model" isExecutable="true">
        <startEvent id="414-013"></startEvent>
        <scriptTask id="javascriptScript" name="jsTask" scriptFormat="JavaScript" activiti:autoStoreVariables="false">
            <script><![CDATA[
                var my = "Bla bla bla";
                console.log(my);
            ]]></script>
        </scriptTask>
        <endEvent id="0DC2EF"></endEvent>
    </process>

这个 xml 上传完美，但是当我尝试启动进程时，我有错误：

Reference Error:"console" is not defined at line 3

我也尝试在 js 中创建新表单：

var form = new FormData();

我又犯了同样的错误。

我做错了什么？这是什么错误？

感谢您的帮助

By default JavaScript is included in every JDK and as such doesn’t need any additional jars.

默认 JavaScript 引擎是 Rhino (JDK6, JDK7) or Nashorn (JDK8+) depending on JDK version. These engines do not support browser APIs and therefore don't provide browser specific objects like console. The main purposue of the bundled engines is scripting java, see Java Scripting Programmer's Guide

对于输出使用 print 函数

 var my = "Bla bla bla";
 print(my);
