Gradle task failed

I keep getting this error every time i try to install or reinstall mcreator. By the time the program opens up after installation and starts downloading the components it needs, a window would pop up saying "Gradle task failed" and that it was unable to detect the reason for the error. 

I pasted the error log below. If anyone can help me that would greatly appreciated.
