JSLT Build

[hemakumarg89]

Perhaps a basic question. But I am bit struck here. pls help. TIA

I am trying to build the JSLT jar in my local using the gradle build.
But ./gradlew clean jar command gives me following error. Not sure why the code is not able to view the JSLTParser created by jjtree. Any help is much appreciated. Thanks.

The JsltParser class is created by javacc. You may want to check if the file is actually there:

That should at least tell you whether the problem is that the file isn't created, or whether it's there but can't be found.

From your output I can see the javacc task is at least invoked.
