Seems you are using java 9 or higher

To remove this warning add the following java parameter into groovy bat/shell

--illegal-access=permit

Or define environment variable

JAVA_OPTS=--illegal-access=permit

More info about this and other java parameters:

https://docs.oracle.com/javase/9/tools/java.htm#JSWOR624

BTW, one of the options - switch to java8

What exactly have you done? – daggett Nov 18 '19 at 08:35
i had first run the JAVA_OPTS=--illegal-access=permit ,then run my script. – hardik gosai Nov 18 '19 at 12:02
What operating system do you have? – daggett Nov 18 '19 at 12:23
i have lnux os. – hardik gosai Nov 19 '19 at 08:05
It depends on shell, but try `export JAVA_OPTS="--illegal-access=permit"` – daggett Nov 19 '19 at 08:17
no changes bro , still same output. – hardik gosai Nov 19 '19 at 08:32
How you are starting groovy? Try to find in groovy binaries following script and add this option directly to java start line just before $JAVA_OPTS. https://github.com/groovy/groovy-core/blob/master/src/bin/startGroovy#L264 – daggett Nov 19 '19 at 08:51
