[Mac] Not valid JDK isntalled --- high JDK version causes release failure

These days I searched and posted on the Internet to find out how to solve the problem of not valid JDK isntalled, but there was no result. This uses ant for release, and the JDK version cannot exceed 1.7. I installed the latest jdk1.8 on the Mac, so this error is always reported during the release. How to solve this problem: 1. Download a JDK of version 1.7; (OR) 2. Use the JDK of version 1.6 that comes with the Mac machine. The best way is not to download it, next I will discuss the solution without downloading it:
Step 1: Run "terminal" and enter sudo nano ~ /. Bash_profile // obtain the permission to modify the. bash_profile file and add the following path. Export java_home =/system/library/Java/javavirtualmachines/1.6.0.jdk/contents/home // Add and save the file
Step 2: Return to the terminal and enter sudo nano ~ //. Bashrc // Add the following code

Export java_6_home =/system/library/Java/javavirtualmachines/1.6.0.jdk/contents/home

Export java_8_home =/library/Java/javavirtualmachines/jdk1.8.0.jdk/contents/home

// Add and save the file

Step 3: Return to the terminal and enter source ~ /. Bash_profile

Enter source ~ /. Bashrc

These two steps are the modified content.

Step 4: Go to the project directory on the terminal and enter

Cocos run-p Web-M release

Congratulations! Release !!!
