cvc-complex-type.3.2.2 attribute 'uuid' is not allowed to appear in element 'jasperreport'

In iReport Designer, in the options window you can change compatibility mode to the version you prefer. For me if I put compatibility to jasperreport 3.5.1, when I save the report again, the uuid are all removed.

I found an answer:

I opened the JRXML file with notepad++ and did a "Search and Replace" of uuid="\w*-\w*-\w*-\w*-\w*", and selected REGULAR EXPRESSION, with empty string then all the occurrences of this wrong tag were removed.

Worked for me.

Open report in the notpad++ and just only remove uuid and it's number.. After You will compile proper and generate report.... I have same problem and I solveby this way..
