YetAlpha opened a new issue, #15768:
URL: https://github.com/apache/dolphinscheduler/issues/15768

   ### Search before asking
   
   - [X] I had searched in the [issues](https://github.com/apache/dolphinscheduler/issues?q=is%3Aissue) and found no similar issues.
   
   
   ### What happened
   
   When I want to use variables in the java node, the configuration does not take effect. Checking the running log did not replace ${var} with a specific value.
   
   The shell1 node passes the set_val variable value, and shell2 and java1 use the set_var variable; during actual operation, shell2 can read the set_var variable correctly, but java1 cannot.

   ### What you expected to happen
   
   I want java1's mainArgs to be replaced with the real value of set_var
   
   ### How to reproduce
   
   It can be reproduced as described above
   
   ### Anything else
   
   I found by looking at the source code that shellTask set properties when constructing IShellInterceptorBuilder, but JavaTask did not. Finally, when producing runShell, the propertyMap is empty.
