Thank you so much, I am able to add java path. I also need to add some
other path as well, so Can I do like this:
*os.Setenv("PATH","/home/sdk/jdk-11.0.16/bin:/home/temp/jtreg/bin:$PATH")cmd,err:=exec.Command("java","-version").CombinedOutput()if
err != nil { fmt.Println(err)}fmt.Println(string(cmd))*
Or Is there any way to add multiple path just we like do with export such
as:
*export PATH=* */home/sdk/jdk-11build/jdk-11.0.16/bin:*
*/home/temp/jtreg/bin:$PATH*
