I think you are right about this one and I believe we should keep all Ant JDBC driver download targets. Except if Gradle is able to infer that it would be possible in certain circumstances an user could need one of those drivers. This would need to parse entityengine.xml and I highly doubt this can be done w/o some human intervention. On the other hand if similar Gradle tasks are introduced, then of course I'd not see any reasons to not drop them. Same for all Ant targets actually.
Hope I'm clear enough :) Jacques
Second Question ----------------------- it seems many of the load tasks are too specific. So I suggest to only implement loadDemo and the rest are executed manually by users, for example: ./gradlew 'ofbiz --load-data reader=seed, seed-initial, ext' instead of load-extseed.I think load-seed is important as well, so if you can keep the load-seed task, it could be fine. Thanks! Julien.If you would like to add the other load data tasks, please specify which ones. Appreciate your early responses.

This is truly a wonderful atmosphere and I am lucky, honoured, and privileged to work with you all on this project. My patch is almost done, but definitely there is a lot of work to be done which includes the following: - I have one failing test out of 889 that I need to dig through, maybe you guy can help - I want to change / delete / add some tasks - Documentation needs to be updated in multiple areas - Testing, testing, testing, testing, testing, testing, testing, testing, testing So the plan of action is as follows: - I will continue the discussion on this thread for a few questions that I need an answer for. - I will issue a JIRA to hold the patch and everything else Please consider helping, this is something that definitely needs a team, more than one brain! If you are working on something not urgent, please consider dropping it for a while and jump along for help. I will post another email soon with the JIRA details and list of questions I need answer for. Again, thank you, you guys rock, I love OFBiz and this community!

So now I will learn gradle ;) and I'm in favor to realize this change directly on trunk Thks Taher to your engine energy on this subject !

If we keep both systems side by side we gain nothing, actually we lose value because the builds become more complex. For example, we will not be able to intrduce the unit tests, and we will have two build outputs, and we will have two ways of running the framework (java -jar ofbiz.jar and gradlew ofbiz) and we will have other incompatibility issues. With that being said, we will not make the switch before a thorough and full testing. That is why we ask everyone who is willing to please help us out to make this transition smooth by testing and providing feedback and comments.

Two weeks ago the community discussed and agreed to the use of Gradle to help us put together a unit test framework. While trying to get this set up while Ant remained as our build tool became verydifficult.This was because our Ant scripts: - are massive and contain a lot of code - are complex - are very brittle and make it very hard to change things - have no dependency management - need everything to be declared We realised very quickly that the re-factoring issues and limitations we are facing are because of our build tool – Ant. Ant is verbose so it needs everything to be declared. We did a brief assessment of Maven and found it better than Ant but not a good fit for OFBiz because it has strict requirements for the convention-over-configuration rules to work. Instead we decided to take a closer look at Gradle. So why Gradle? As Taher was already looking at Gradle for unit testing, we decided to look at what we would need to do to totally replace Ant with Gradle. We received some great support and feedback from David, who is already using Gradle with Moqui. After some preliminary tests we found that Gradle has some very good features such as: - a much shorter code base (e.g. one single file of around 250 linesofcode replaces all the build.xml files and thousands of lines of code) - Programming is DSL based and links in well with Groovy (e.g. the script is short because despite heavy custom requirements for OFBiz, two small functions took care of the complex directory structure) - It handles all the external jar files by downloading anydependenciesdirectly via internet - Jars can be upgraded by simply changing a string - It has matured a lot and has a high level of support in tools,IDEs, books, documentation - It also has a lot of plugins which means that it works with pretty much all build systems, supports multiple programming languages, and many other features (e.g. OSGi) We understand that it can help us make OFBiz more modular and alsosettingup a framework for managing addons would be a lot easier. So what's been done? Taher has been working very hard on a patch for the trunk that completely replaces Ant with Gradle. (Huge thanks to David for providing someexamplescripts to help us get started!) The patch is now ready to be applied to the trunk and includes the following: - java -jar ofbiz.jar is now replaced with -> gradlew 'ofbiz --whatever-options-here' - In addition to gradlew 'ofbiz' we also have gradlew 'ofbizDebug --whatever'. What does that mean? It means we can run debug on ALL ofbiz commands, not just start - If we decide to change the source directory structure in components say from /src to /src/main, it would literally be a change of 5charactersin the build script - We can immediately move all jar files if we want to a unified location in /lib for example - We can delete most of the jars and declare them as dependencies saving space and resources - We can automate the creation of the .classpath file so when we update libraries no need to do this manually (under development) - We can ignore components that are not define in the xml files for loading (under development) - We can introduce unit tests with about 10 minutes of work We are finding that the flexibility and control we are getting withGradleis truly amazing. We know that Gradle will be a major change to theprojectbut we think that it will significantly improve the project by removing a lot of build complexity and take care of that essential dependency management that we need to comply with. Our next steps will be to apply the patch to the trunk and then continue the re-factoring work. We will need to organise some knowledge transfersothat all our committers understand what the changes are and how theywouldneed to work in the future. The PMC are very, very excited about having Gradle as part of future of OFBiz and we hope that the community will think so too. As always,feedbackwelcome. Thanks Sharan
