Space in the path will not work. Simply remove any spaces in the path.

In my case it is working with:

set JAVA_HOME=C:\Progra~1\Java\jdk1.8.0_261

Answer 2

Your JAVA_HOME should not include bin. Change it from

"C:\Program Files\Java\jdk1.8.0_45\bin"

to

"C:\Program Files\Java\jdk1.8.0_45"

And you can add it to your path (in Windows) like

set "PATH=%PATH%;%JAVA_HOME%\bin"

Issue was with space in JAVA_HOME path . I change the path as below and it started working.

"C:\Program Files\Java\jdk1.8.0_45\bin"

to -

"C:\PROGRA~1\Java\jdk1.8.0_45\bin"
