If you're trying to run Jaspersoft Studio on Ubuntu, you need to use runubuntu.sh script instead. Some versions of Jaspersoft Studio doesn't work properly on Linux platform - try using a different version of Jaspersoft Studio. I'm currently using 6.3.0.

I found a solution to this problem.

1- Select the PROPERTIES of .METDATA folder

2- Select PREVIOUS VERSIONS

select the most current previous versions and select RESTORE.

This worked for me. Just be aware that you should have a recent backup of any .JRXML files before attemtping the RESTORE of PREVIOUS VERSIONS
