Crontab timed run jar not executed

Crontab regularly runs jar without executing-Linux general technology-Linux technology and application information. The following is a detailed description. I wrote a test. jar application and used java-jar test. jar in the command line to run normally. However, I used a shell script to run it regularly through crond without executing test. jar.
The script is written as follows:
#! /Bin/bash
Cd/usr/local
./Etc/profile
Java-jar test. jar

Crontab is defined as follows:
0 11 ***/usr/local/test. sh

Both test. jar and test. sh grant the 777 permission.
But by, no execution or error is reported.
Urgent! Hope you can give me some advice! Online, etc!
