Hi Andrew, guess I'll start with the fork and contact you folks on slack. Chris Am 16.04.20, 19:43 schrieb "Andrew Musselman" : Chris, thank you for your help.. Yeah if you fork what's in master you can see what state it's in; we are in the #mahout channel in tge-asf slack and this is also a fine way to keep track of discussion.

Re: Hi ... need some help?
Hi Trevor, ok ... first of all ... the Mahout PMC is defining a "community maintained" library which is not maintained by the mahout PMC?!?! I thought at Apache everything is about Community over code. So is a company driving the non-community stuff? But back to your build issues: I had a look and I too encountered these comments and remarks and sometimes patterns I recognized and could imagine why they were created. Yes quite a bit of the build could be cleaned up and simplified a lot. So how about I create a fork and try to do a cleanup of the build. Usually I also leave comments about what I do as I hope I'll not be the only one maintaining a build and documenting things helps people feel more confident. However in some cases I will have questions ... so would someone be available on Slack for quick questions? Usually switching to another build system does solve some problems ... mostly the reason to switch is that it solved the main problem that you are having with the old. However you usually notice too late that you get yourself a lot of new problems. I remember doing some contract work for an insurance company and they were totally down Maven-road but then had to build something with SBT ... in the end I compiled the thing on my laptop, copied it to a USB stick and told the people what was on the stick and that I'll be having a coffee and will be back in 30 minutes. When I came back the sick wasn't at the same place and the build problem was "solved" ;-) So I think it's quite good to stick to maven ... that is very mature, you can do almost everything you want with it and it integrates perfectly into the Apache infrastructure. But that's just my opinion. So if you want me to help, I'll be happy to be of assistance.

Hey Christopher, I would agree with what Stevo outlined but add some more context and a couple related JIRA issues. For 0.14.0 We did a big refactor and finally moved the MapReduce based Mahout all into what we called "community/" that is community maintained, which is to say, we're not maintaining it anymore (sunset began I think in 2015).

Re: Hi ... need some help?
Hi Stevo, so let me summarize what I understood: - There are some modules in mahout that are built with Scala, some with java and some with both (At least that's what I see when checking out the project) - The current build uses Scala 2.11 to build the Scala code. - The resulting libraries are only compatible with Scala 2.11 Now you want to also publish versions compatible with Scala 2.12? If that's the case I think Maven could easily add multiple executions where each compile compiles to different output directories: - Java --> target/classes - Scala 2.11 --> target/classes-2.11 - Scala 2.12 --> target/classes-2.12 Then the packaging would also need a second execution ... each of the executions bundling the classes and the corresponding scala output. Ideally I would probably use maven classifiers to distinguish the artifacts. org.apache.mahout mahout-spark 14.1-SNAPSHOT 2.11 Then it should all work in a normal maven build. In the distributions you could also filter the versions according to their classifiers. So if this is the case, I could help you with this.

Mahout maintainers and contributors, should consider alternative approach, one of them being switching to sbt - it's scala native, supports scala cross publishing, supports publishing Maven compatible release metadata and binaries.

Disclaimer: I'm not active Mahout maintainer for quite a while, have some historical perspective, take it with a grain of salt, could be I'm missing the whole point you were approached for by a wide margin of error. At a point Mahout, some of its modules, have turned into a scala library, and there was need to cross publish those modules, across different scala versions.

Switching to sbt could have solved the problem. Switch was deemed to be too big task, even though ages have been spent on trying to apply Maven (profiles) + bash scripts and what not to solve the problem. Trying to apply same approach over and over again and expecting different results is not smart, no expert can help there. Mahout maintainers and contributors, should consider alternative approach, one of them being switching to sbt - it's scala native, supports scala cross publishing, supports publishing Maven compatible release metadata and binaries. Kind regards, Stevo Slavic.

Hi ... need some help?
Hi folks, my name is Chris and I’m involved in quite a lot of Apache projects. Justin approached me this morning, asking me if I could perhaps help you. He told me you were having trouble with doing Maven releases. As Maven releases are my specialty, could you please summarize the issues you are having? Chris
