dts-gen - Java.type()

[uuk007]

I am trying to generate TypeScript definition file (.d.ts) from JavaScript file (*.js)...It has converted most of the files expect js file contains the following statement

return Java.type('com.test.TestExample').START_ELEMENT

When i compile the file, i am getting the following exception:

ReferenceError: Java is not defined
at Function.get ATTRIBUTE [as ATTRIBUTE] (eval at <anonymous> (C:\Users\uuk\AppData\Roaming\npm\node_modules\dts-gen\bin\lib\run.js:71:64), <anonymous>:95:27)

I feel modules related to Java is not getting loaded...

Can you please help me to resolve this?
