TeamCity has a very easy interface to re-order the build queue. Simply drag and drop.
Is there any way to re-order or prioritise build queue on hudson ci servers?
As far as I know, not yet.
There is the issue 833 which ask for this kind of feature since 2007, and there have been recent development in the code base in that direction, based on the QueueSortingHandler.
But I don't know if any plugin has already taken advantage of that feature.

Disclaimer: I am relatively unfamiliar with the flash build processes, so some/all of this may be misinformed nonsense. Please feel free to suggest alternative approaches.
We're currently developing a flex web app and our build situation is far from ideal. At present we're (as in individual developers) just building using FlashBuilder and deploying manually. The programmers are currently screaming bloody murder for two reasons, though:
The lack of CI is like going back to the stone age
We don't much care for FlashBuilder
(Note: We're only using FlashBuilder because it was the easiest way to set up a flex project in conjunction with Away3d and get it building / rendering correctly -- it's a stopgap solution).
As a predominately .NET development shop, we're used to doing continuous integration as well as continuous deployment. Ideally, we'd like to get something comparable to this for our flash projects without tying ourselves to a particular IDE.
Requirements:
The build process must be:
.. runnable via the commandline
.. runnable on both developer and CI build machines (and certainly not requiring an IDE!)
.. preferably as IDE-independent as possible (pragmatism will kick in though; if this causes a lot of friction we'll just pick one).
.. able to run on Windows (we develop using Windows)
We don't mind a touch of duplication or a few manual steps (e.g. tarting up the build scripts if we add a new project via an IDE, or generating one configuration from another if tools exist), but the less duplication / maintenance required the better.
I've read quite a few articles / blog posts and watched some short screencasts, but most of them are very thin on the ground on how the build system sits alongside IDEs. Most articles/screencasts have the same formula: How to create a "Hello World" build using a single file & text editors (no IDE).
I've not seen the topic of multiple libraries/projects etc. being broached, either.
After reading around the issue for a while, I'm considering investigating the following options:
Project Sprouts
Flexmojos
Maven Flex Plugin
buildr as3
Does anyone have any experience of the above solutions (or others I'm unaware of) and, if so, what do you make of them? Any help / pointers appreciated.
I recently started building with Gradle and the GradleFx plugin and I immediately fell in love with its power and ease of use.
Gradle is ANT + Maven + Ivy evolved and is primarily used from the command-line. You can:
write scripts in Groovy (a powerful Ruby-like language that runs in the Java Virtual Machine)
access all existing Maven and Ivy repositories as well as your own repos
use existing ANT tasks
integrate with CI (in Jenkins you just tick a checkbox to activate Gradle support)
although it has originally grown from the Java/Groovy community, it is in fact language agnostic. You add language-specific plugins for added functionality. GradleFx is such a plugin that provides you with additional ActionScript/Flex building tasks.
do easy multi-project builds. e.g. you can compile, unit test, package and deploy both your .NET service layer and your Flex client application with just one command.
use convention over configuration: if you stick to the conventions, your build scripts will be extremely terse
generate all kinds of reports: unit testing, checkstyles, codenarc, ...
generate Eclipse, IDEA or other IDE projects
all the things I haven't discovered yet
And best of all: it's very easy to learn. I had no knowledge of Maven before I started with Gradle and could get a multi-project build with some customizations working quite quickly.
Edit (comparison to Buildr AS3 and Maven)
I can compare this only to one of the projects you mentioned: Buildr AS3. It seems to start from a philosophy that is similar to Gradle's. But I've tried to use it about half a year ago and couldn't even get a simple 'Hello World' app to work. I e-mailed the developer for help: no response.
Compared to GradleFx: I had a small forum discussion with the developer (on a rather philosophical topic, since I didn't really need any help because it just worked right away). He answered within minutes.
As for Maven: (for what it's worth) I've only glanced at some configurations and they seem overly complicated when I compare them to a Gradle script.
There is one thing Maven does that you can't do with GradleFx (yet). It can pull the right Flex SDK from a Maven repo and build against that. With GradleFx you have to have your SDK's available locally.
I'm quite familiar with using maven as the main build tool and the flexmojos plugin from Sonatype. My experience has been a bit of a roller coaster with flexmojos. Maven is completely solid, it works all the time without issue, the only issue is the flexmojos plugin which has fluctuated a lot between versions. If you choose to go this route make sure to grab the source for flexmojos so you can see what your configuration options are actually doing to the command line parameters etc. For Flex 3.x flexmojos 3.x up to around 3.9 is good and works fine with regard to the goal for generating the .project eclipse files, believe there's also a mojo (a maven plugin) for generating intelliJ IDEA project files as well as others. If you're using Flex 4 you can compile with the latest flexmojos 4.0RC2 but it appears to me that the goal for generating flex/flashbuilder project properties is now gone (I'm not sure if this is because it's been replaced by another plugin altogether or what the deal is). However building with maven and flexmojos does fulfill all of your goals above (we also use it for building our service layer, so in a single mvn clean install we get a jar packed in a war packed in an ear with everything configured and a swf, that part is really nice). Also you can do continuous integration using bamboo (or simply write your own script that is triggered from a cron job or in windows as a batch file executed with a scheduled task if you don't have a *nix server around). Let me know if you'd like any more details or if I missed something major.

I have been using Hudson, now Jenkins, with Ant for Flex automated builds and FlexUnit testing. Jenkins has some really useful plugins for integration with eclipse (and hence, FDT or FlashBuilder), Jira, SVN, Git etc., and it's free. Also, you can integrate the Ant build into Maven scripts, so I've found this to be a good and flexible solution for all purposes I've come across so far.
The Flex SDK comes with Ant tasks, and writing even elaborate Ant build scripts is quite easy - in fact, I'd been using Ant locally before, and I could reuse my existing scripts with only a few added extra compiler options for FlexUnit tasks.
However, it took a while to set up the system correctly for unit testing, because I'm running a headless server on Linux, and that implicates a rather complicated environment for ActionScript tests, because they run only in Flash Player. This, of course, is true for all CI scenarios using FlexUnit, regardless of which server you use.
Here's what I've learned:
FlexUnit needs a standalone debugger version of Flash Player installed, but Adobe only distributes binaries for the standard version on Linux. Therefore, compiling from source was necessary, and since my server system is stripped down to the bare necessities, it took some effort to install all the correct dependencies and get them to work.
The Flash Player needs hardware to run correctly: It uses graphics, therefore it needs a graphics card, and sounds, therefore it needs a sound card. On my headless server, this meant I had to install a VNC host to get it to run at all, and I had to eliminate any tests using sounds (those will now only run on local machines). If anyone ever comes across a working sound card emulation for openSuSE that I could use with the VNC client - you'll be my hero forever!
If you've set asynchronous timeouts in your unit tests, and/or you need to use setTimeout() to send delayed procedure calls, make sure the intervals aren't too short - I've had problems with tests that ran fine on any local machine, but broke the build on the CI server, because the Flash Player is considerably slower on the VNC client than on an actual graphics card.
I've also found this last issue to be a healthy lesson: Criteria for unit tests should not be based on assumptions about the system's performance, or at least be tolerant enough to succeed even on a slow machine.
I've just moved a large project out of a legacy version control system, and into Mercurial. I'm now faced with the task (opportunity!) of overhauling my old build system to work with this new source control system.
Are there any good build systems that:
Can build projects in a variety of languages and compilers
Integrate well with Mercurial (For example, knowing to pull certain revisions or tagged versions of sub repositories for dependency management (as opposed to continuous integration.))
Extendable (we have several auditing steps that we need to perform before and after our build)
Are easy to use
that are already out there? As much fun as building and maintaining yet another build system might be, I'd rather reuse a mature, stable product and get back to developing my own code. :) If no tool exists with Mercurial in mind, what else might meet the requirements? What else might be out there that I'm forgetting?
Usually your build tool/system and your continuous integration system are separate, and the later is the one that knows about your DVCS system. In my setup the build tool is sbt (formerly ant) and the CI system is Jenkins (which I highly recommend).
The CI system speaks Mercurial, but it doesn't have to speak much of it. Mercurial lets you create URLs that track a specific named branch or tag, and so long as your CI system can clone/pull you're set. Once the CI system has updated to the version you want to build then it triggers you build system, which needs only look at the working directory.
Our group uses Visual Sourcesafe as a file repository for all of our "content" (HTML, CSS, Javascript, JSP). None of it requires building or compilation but we would like to automate the copying of it to a Unix dev server upon check-in.
I have used Cruisecontrol.NET in the past for CI at other companies but it was for .NET. What would be the easiest way to achieve our current requirements? Would using CruiseControl.NET be overkill or even a good idea? Thanks in advance.

This sounds like overkill for a CI tool.
Visual SourceSafe and other version control systems should have hooks allowing you to automate a simple file copy operation.
From http://msdn.microsoft.com/en-us/library/aa302175.aspx
Use events, such as OnBeforeCheckout
or OnAfterCheckIn to automate your
process.
Whether this makes sense for you depends on a couple of factors. If you are talking about a large, geographically team with only change based deployment then yes, those are valid concerns. If you only have a few local developers and you deploy the world on each copy operation, then no, I don't think you'd need a CI tool.
This is not to say other reasons may influence you to use a CI tool, testing for instance. Your problem might also be solved by running a polling script on the Unix box to sync the source control with the dev server. I guess the main point is, if you are deploying all non-compiled software, why do you have a separate source control and dev server? You're deployment can be done by a source control tool. If it is only for backup, there are plenty of existing solutions for that problem.
Sean,
Our AnthillPro customers do this kind of thing pretty frequently (and we even do it internally when new content is committed for our website). It's a really good idea, totally appropriate for a CI tool, and you can get quality feedback if you wire in some automated functional / regression tests.

You could try using Hudson http://hudson-ci.org/
It is easy to configure, is completely GUI (unless you want to go into the details), and has a plugin for Visual Sourcecafe http://wiki.hudson-ci.org/display/HUDSON/Visual+SourceSafe+Plugin
While CI would probably be overkill for what you are trying to do, since Hudson is all GUI and easy to use, you would not spend a lot of time just trying to configure it.
Hudson also has plugins for copying stuff over to other systems, and so it would be easy to deploy your content to another system.
If you are worried about the process, get in touch with a hosted CI provider, such as MikeCI, a quick message on their support board will get you the answer. I don't see why triggering a "build" can't be replaced with copy and paste!
I observed that there are 3 plugins that are aiming to provide hudson integration in IntelliJ IDEA.
What is the better one and why?
Hudson Build Monitor seems like the only reliable option where IDEA plugins are concerned. The other available plugins seem to be buggy and perhaps a little over-engineered.
At a basic level HBM works great though I'd prefer it were more project-specific as opposed to monitoring a view or the entire list of Hudson jobs.
I'd like to see a more abstracted build monitor option. Perhaps a Maven plugin that is configured with a CI server facade and references to all the builds for a specific pom file. Then a generic integration within IDEA to poll that facade on a timer to display the status within your project view. This same abstraction could be integrated into the Maven reporting subsystem to document the build history of a specific release through the development cycle.
As usual, plenty of IDEAS and not enough TIME :-)
I'm using the Hudson promoted build plugin to try an automatic deploy if all of the maven projects are good.
My setup is similar to the following
Hudson job creates a version control tag and then triggers downstream builds of projects A and B. A triggers a downstream project Z.
I currently have the promoted builds plugin listening for success of A,B,Z. But no promotion ever happens.
I currently don't have the project triggering all 3 since there is no point in building Z before A.
Any ideas?
I think you need to configure fingerprinting so that Jenkins can keep track of which downstream build tested which upstream build.
You could try the Build Pipeline Plugin, or take some inspiration from Kohsuke's recent blog post "Doing choreography/workflow with Jenkins CLI" (login with CloudBees/Google/GitHub account required) which should give you more freedom in orchestrating your jobs.
