Taher Alkhateeb commented on OFBIZ-7534:
----------------------------------------
Thank you for the wonderful feedback Ashish!
So, a few feedback points:
- Ant is an imperative tool (do things in sequence) whereas Gradle is declarative. Because of this difference, the Gradle output is very different from ant when doing ./gradlew whatever --info. So we have multiple solutions for this, for example, we can loop over all components and compile them one by one separately in a different configuration classpath and then combine them together at the end. It's a bit of a pain to get the code right but nothing major. Another solution is to write custom logger.info or println statements to show what is going on during the compilation process. Yet another option is to break the compilation process into the subprojects. I will think some more of the best solution and I'll put it in the list of future things to do to improve the output of Gradle
- Ctrl-C does not work with Gradle because it is a powerful engine that can do multiple tasks in parallel by spawning threads and processes. So a simple Ctrl-C does not work because it only kills gradle, not the other sub-processes. So I am going to work on a new task called terminateOfbiz which searches for running instances of OFBiz and kill them.
- Hmmmm, very good point on the database. Should I let Gradle check if a database exists, and if not then terminate with a clear message? It would be easy to check if a derby database exists, but what about the others? should I establish a JDBC connection?
Great feedback, very useful information, thank you!
