### Search before asking - [x] I had searched in the [issues](https://github.com/apache/dolphinscheduler/issues?q=is%3Aissue) and found no similar feature requirement. ### Description Currently, java tasks do not support replacing custom variables or built-in variables. I think it's necessary to support this. - For example, as shown in the following figure, when I'm scheduling java tasks, I can obtain the available memory of the current machine through the upstream shell task and then pass it as a jvm parameter to the downstream java task. - For example, the input parameters of a Java job can also come from results computed by an upstream task. <img width="630" height="611" alt="Image" src="https://github.com/user-attachments/assets/c026b41d-48f9-4993-8e15-e2632b274171"; /> <img width="640" height="659" alt="Image" src="https://github.com/user-attachments/assets/c8452cff-a1e4-4be2-881f-40d7c1904119"; /> ### Are you willing to submit a PR? - [x] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
