| Riddell | Koon: yeah I want to package, sesame | 16:08 |
|---|---|---|
| Riddell | I have it building ok on my machine, but in a chroot it insists on downloading files (which won't work for a buildd of course) | 16:09 |
| Riddell | http://paste.ubuntu.com:80/117702/ | 16:09 |
| Koon | hm. | 16:09 |
| Riddell | so something seems to be different about my own system that it doesn't need to download stuff | 16:10 |
| Riddell | but I've no idea what | 16:10 |
| Koon | For simple things that happen to use maven, there is the possibility to use maven-ant-helper that basically wraps the buid into a simple ant build.xml | 16:10 |
| Koon | but Sesame looks large | 16:10 |
| Koon | (looking at that reactor build order) | 16:11 |
| Riddell | it's a beast | 16:11 |
| Koon | For medium-sized thing we expect to have support for Maven packaging at the start of jaunty+1 | 16:11 |
| Koon | (synced from twerver work in debian) | 16:11 |
| Koon | twerner, I mean | 16:11 |
| Riddell | but it works, I just don't know how | 16:12 |
| Koon | however very large things would probably still fail, since we would provide a unique version of each artifact when the very large thing usually will ask for several versions of the same artifact and fail if you cheat it | 16:12 |
| Koon | I fear Sesame falls into the last category | 16:13 |
| Riddell | Koon: want to see if it builds for you? http://www.kubuntu.org/~jriddell/tmp/sesame/ | 16:13 |
| Koon | i'm pretty sure it builds. The problem is working around the online download of deps | 16:13 |
| Riddell | but it doesn't do the download on my laptop | 16:13 |
| Riddell | only in a chroot | 16:13 |
| Riddell | is the download cached somewhere? | 16:14 |
| Koon | yes. ~/.m2 | 16:14 |
| Koon | the method we use is to provide to the build something that looks like the repository maven would have ended up downloading | 16:15 |
| Koon | but that in reality would link to the system-installed JAR artifacts | 16:15 |
| Riddell | bah fooey | 16:15 |
| Koon | There wrer two implementations of those, the one we speced i nUbuntu and the one Debian-java finally started | 16:16 |
| Koon | We discussed that last week with twerner and decided that we should use Debian model since it's better for us to sync it from them | 16:16 |
| Koon | rather than go our own slightly-different route. Furthermore their design was done by someone that kinda knows maven. While our design was done by me ;) | 16:17 |
| Riddell | what an insane build system | 16:17 |
| Koon | so we expect to be able to build a helloworld maven project at the start of the Jaunty+1 cycle | 16:18 |
| Koon | but something like Sesame or geronimo is still a very long way | 16:18 |
| Koon | You /could/ rewrite the Sesame build system completely so that it does not use Maven, but that's a hell of a work. | 16:18 |
| Koon | so doko summarized our current advice very well :) | 16:19 |
| Koon | Riddell: yes, that's a quite insane build system. Makes (some) sense if you only build binaries once. Which is kinda the idea behind Java. | 16:21 |
| Koon | But from a distro pov it's simply a walking nightmare | 16:21 |
| Riddell | and people wonder why java has a bad reputation in the free software world | 16:21 |
| Riddell | Koon: and there's no way to just include the files it would cache? | 16:23 |
| Riddell | i.e. fake the cache | 16:24 |
| Koon | Riddell: well, you could tar up the repository it caches, include it as part of the sources, and run mvn in offline mode to make sure it does no freshness check | 16:24 |
| Koon | but that would be including binaries as part of the source | 16:24 |
| Koon | which is no-no for most repositories, if not all. | 16:25 |
| Riddell | most of the files are there .pom XML files | 16:26 |
| Koon | there are quite a few JAR files normally. | 16:26 |
| Riddell | there's a bunch of .jar files but they ought to be packagable I'd have thought | 16:26 |
| Koon | you'll also miss "maven plugins" | 16:27 |
| Koon | yes, it's basically a packaging effort and some tools to help in the process | 16:27 |
| Koon | but since we provide a single version of each artifact, slightly different from the one Maven requests, it /may/fail | 16:28 |
| Riddell | ok, time to give up I think | 16:29 |
| Koon | since JARs usually break API without warning | 16:29 |
| Riddell | thanks for the information Koon | 16:29 |
| Koon | Riddell: if that's an option, I'd recommend it. | 16:29 |
| Koon | Riddell: you're welcome. I always like to rant about it. | 16:30 |
| Riddell | Koon: is there an easy way to override where maven looks for that .m2 cache? I guess I could package it for multiverse | 16:49 |
| Koon | you have to provide a settings.xml file... hmm just a sec | 16:49 |
| Koon | mvn --settings debian/prepare-settings.xml --offline | 16:51 |
| Koon | with something like http://pastebin.ubuntu.com/117731/ in the .xml feil | 16:51 |
| Koon | file, even | 16:52 |
| Koon | Riddell: got to go. Good luck :) | 16:53 |
| Riddell | thanks | 16:54 |
