Error compiling reports on one particular machine

[pigsie]

One of our projects uses Jasper reports and uses the Jasper reports ant task to compile the reports. On one machine in particular we get the attached error:

However I am hesitant to change any code as this correctly builds on every other machine. This is using JR  3.1.3. This would perhaps indicate that it is a problem with the environment, so I just wanted some suggestions on possible causes for this error or how to go about getting to the bottom of this.

 

Many thanks

Which report compiler are you using?  See the FAQs on report compilation.

I believe it is using the JDT compiler - I am compiling the project using the ant task from inside Eclipse. I had a read through the FAQ and a book but am still no closer to solving this. As it works on other machines ... I'm guessing it has something to do with my environment..?

Also see this other FAQ on compiling Java 5 expressions.

Note that even if you are compiling reports by launching Ant in Eclipse, you still need to explicitly include a JDT jar on the classpath in order to use the JDT compiler.
