I get exactly the same error as you when creating a Grails 3.3.5 project in NetBeans 8.2 on Windows 10. This is because of a longstanding bug in NetBeans: Bug 258407 - Error when creating a Grails 3.1.x project, which also impacts more recent releases of Grails.

Although that bug has Status: VERIFIED FIXED, unfortunately the fix was not applied to release 8.2 itself ("...this bug is fixed in development builds not 8.2"). You have two possible workarounds:

• Install a DEV build of NetBeans 8.x which contains the fix.
• Install the beta release of NetBeans 9.0 which contains the fix.

Option 1: Using a DEV release of NetBeans

• Download the most recent nightly Dev build of NetBeans 8.2.
• Activate Groovy and locate Grails 3.3.5 in the same way as you did on NetBeans 8.2.
• You can then successfully create your Grails application using the Groovy > Grails Application project wizard, and run it:

Option 2: Using a beta release of NetBeans 9.

• Download and unzip NetBeans 9 beta from the Apache NetBeans 9.0 Beta web site.
• Start NetBeans 9 beta and install the Groovy/Grails plugin:

• Locate Grails 3.3.5 in the same way as you did on NetBeans 8.2 (Tools > Options > Miscellaneous > Groovy > Grails Home).
• You can then successfully create your Grails application using the Groovy > Grails Application project wizard, and run it:
