2. Configuration environment variable
   JAVA_HOME:
   

CLASSPATH:

The PATH:

3. Installation eclipse
   me up and down the eclipse at the following Web site
   to add a link description
   
   so he came to me the most ignorant forced to stage ......
   I open the installer, then jumped out of the page
   

Then I also follow bigwigs say two or three times of heavy eclipse and JDK, version of the problem for fear of also installed over JDK8u241, but eventually the same result. I do not know what caused the problem. Hope you can give some help (┬_┬).
