Java exception while trying to start Grails

That's it - I just downloaded the latest versions of Grails (2.1.0) and JDK (1.7.0_07) on my computer with a 64-bit version of Win7 and configured my machine as follows:

1.) Added environment variables for Java and Grails
2.) Update PATH depending on the situation 3.) Make sure that everything is installed correctly by doing java -versionandgrails -version

The command java -versionworks and shows the following:

java version "1.7.0_07"
Java(TM) SE Runtime Environment (build 1.7.0_07-b10)
Java HotSpot(TM) 64-Bit Server VM (build 23.3-b01, mixed mode)

but the command grails -versiongives the following error:

Exception: java.lang.RuntimeException thrown from the UncaughtExceptionHandler in thread "main"

I tried debugging, completely removing all Java, and then reinstalling, but the same error. I verified that I installed the 64-bit version of Java.

Finally, the problem was resolved by removing ~ / .m2.

BTW, "set DEBUG = 1" before running "grails" at the command line will show the environment and options for starting Java.exe.

I had a similar problem, but on Ubuntu 12.04. I solved this by deleting the $ GROOVY_HOME environment variable. If you also have the $ GROOVY_HOME variable, try deleting it.

Try deleting the file .grails_historylocated in your directory %Home%. This worked for me on Windows 8.1
