I have a (standard non-maven, non-gradle, non-whatsoever) project in IntelliJ IDEA that consists of several modules.
One of those modules results in a jar that is used by one of the other modules.
I have two artifacts. The first one creates a war file. This one depends on the jar file built from the second artifact.
How can I order the build process of the two artifacts so that the second one creates the jar file and copies it to the lib folder of the first, before the first one builds, without the need to recreate both artifacts?
As soon as I select "Build/Build Artifacts/All Artifacts" it always tries to build the first one first.
EDIT: Maybe a better question: What is the recommended way to manually build several artifacts in order of their dependencies?
How can I [configure IDEA] ... so that [it] ... creates the jar file and copies it to the lib folder of the first...
You can't really configure IDEA to do this directly. While you can configure Artifacts in the Project Structure dialog, there are no provisions for copying artifacts. IntelliJ IDEA is an IDE, not a build tool. While it can do a lot regarding complying and building, it has its limits.
One possible hackish way would be to go to the Artifact definition in the project structure. There, there are "Pre-processing" and "post-processing" tabs, They have the option to run an Ant target. So you could create a simple Ant target to do the copying. But in the end, I think the best answer to your question:
Maybe a better question: What is the recommended way to manually build several artifacts in order of their dependencies?
is to use a build tool such as Ant, Maven, or Gradle for building the project.

I have a project in IntelliJ IDEA, inside that a couple of modules and one of my modules has two build configurations. One of them needs to copy a <projectroot>/tools folder to its out/production/<BuildConfigurationName> folder. Can IDEA somehow automate this?
The accepted answer above is incorrect. IDEA can do this (without ant/gradle) via the artifacts system (accessed via Build menu or project settings). Any one artifact job copies multiple files/folders/build outputs to a chosen location (optionally jarred) and can be set to automatically run on make.
Artifacts can even be chained, i.e. output from one as input to another.
Can IDEA somehow automate this?
Not directly, no. Ultimately IDEA is an IDE and not a build tool. While it can do a lot during a build, it does not have the ability to copy non-source files to an alternate directory, let alone a dynamically named directory.
If you marked the tools directory as a source directory (and none of its contained file types were set in the "Ignore files and folder" setting at the bottom of the "File Types" settings dialog), IDEA would then copy the tools directory to the out directory. But renaming requires a more sophisticated build tool.
Ultimately, the "ideal" or "best practices" solution would be to build your project using a build tool like Maven, Gradle or Ant for which this type of thing would be a snap.
If that is not an option, or for some reason you really want IDEA to do the build, the best thing you could do is to write a simple Ant script to the copy for you. (Or possibly Gradle, I do not have much experience with Gradle yet. Maven could do it, but it'd be a bit cumbersome compared to Ant.) In any Run/Debug configurations, you can define the ant script target to run before or after the IDEA "make" in the Before Launch section. (You can set that as a default for any newly created configurations by configuring it in Defaults on the left). If you run your build manually, you can assign a shortcut to the ant build and then run it and the make in sequence. Alternatively, you could record a Macro (Edit > Macros) to run both in sequence and then (optionally) assign the macro a keyboard shortcut.
OK, lemme set the stage. I have a parent pom, project_maven, that contains 3 modules in its POM, project_common, project_explode, and project_client. project_client has dependencies on both project_common and project_explode. project_client also contains an /ext directory, which contains third-party executables, scripts, etc.
In our current Ant build of the project, there is a target, build-client-tarball, that copies the /ext directory to the build directory, copies the project_common.jar and project_explode.jar files into specific locations in the build dir, and tarballs the whole thing.
I'd like to duplicate this behavior in maven without having to resort to calling the ant tasks. From what I can tell, it looks like the assembly plugin might be the way to go, but I'm having trouble figuring out how to get it to work. Seems like I would need a custom assembly descriptor? Anybody have any boilerplate or examples I can work from?
You need to use the Maven Assembly plugin. It's worth the effort to investigate it. It will do exactly what you need.
You can use it to include dependencies and sources. Have a look at this link. There're a bunch of sample assembly descriptors there. You need to define a format tar in order for it to produce a tar for you. In addition, you also need to define <dependencySets/> in order to include the modules you mentioned.
I have a situation that I'm sure must be fairly common. I have some Maven-built applications that deploy to different types of application server - like Tomcat, JBoss, etc.
The build processes 'tunes' the deployable artifact to the specific target type of application server (for example, different included dependencies, context roots, other config). This tuning is controlled with build profiles (-Ptomcat, -Pjboss etc)
So, for a given version of my application, I need to run builds that produce different deployables. I run mvn -Ptomcat clean package for example and I get an artifact in my /target directory that is the tomcat-tuned version.
The best approach I've been able to come up with so far is to specify finalnames for the artifacts that include the profile information, but for that approach, I'm not sure how to configure Maven to copy the final artifact off to some specific location so that the next build for a different type doesn't overwrite it.
Is this a good approach? If so, how can I achieve that final copy?
Or is there a better way?
You'll need to use Maven Assembly Plugin.
I have a project that uses the built-in IntelliJ build system. What's the quickest/best way to migrate the project to Maven?
What's the quickest/best way to migrate the project to Maven?
Manually. Here is what I would do (I would personally use the command line):
create a parallel (potentially multi-modules) project structure using archetype(s)
declare dependencies for the jars you're using (not all of them, you'll get some transitively)
move sources and resources to the new structure
test the build
import the project back into your IDE
IDEA understands Maven very well. Unfortunately it does not create Maven configuration for you.
You'll have to write pom.xml yourself. The complexity of this depend on the structure of you project and frameworks/libraries that you use.
For me the easiest way is to create a new project based on artifact and then copy existing source files into it. You can do this in IDEA:
File -> New project -> Create project from Scratch
Choose Maven module, Next
Check Create from Artifact: a list of available artifact will show. Choose one based on libraries/frameworks you use. You can also add one if it's not on the list (search the web).
When project setup is done, start copying sources.
Bear with me, I'm migrating from Ant to Maven2: I think I've hit one of those little things that was easy in Ant, but not so in Maven...
How do I handle the difference between a local deployment vs. creating an archive/bundle for distribution to another machine?
Let's assume my project's output is an EAR plus some additional config files. A developer that is actively working on the project will need to deploy and re-deploy frequently to his local app-server (say JBoss), while an Integration Engineer that is building for QA/production will need only to create the final archive assembly (tar/gz).
In Ant we had two targets for this: "dev-deploy" and "bundle". Both do a complete build, but differ in the final step: "dev-deploy" copies the EAR and config files to the respective local folders, while "bundle" just puts the EAR & config files in a tar.gz assembly.
How do you do this in Maven?
I've seen that the assembly plugin can create either archives (tar, gz, etc.) or exploded directories (from the same assembly descriptor). I can invoke either assembly:assembly or assembly:directory, but for the latter, how do I copy the final output to the local JBoss deployment folders? From a related post it seems that ad-hoc copying of files is not really what Maven is about, so an antrun copy is probably the most appropriate?
Finally, since the type of assembly may differ depending on who invokes it, it doesn't seem wise to bind assembly to the build lifecycle, not so? But this means that a developer will always need to invoke 'mvn package' followed by 'mvn assembly:directory' to rebuild and test a change. Conversely, an Integration Engineer will always need to run 'mvn package' followed by 'mvn assembly:assembly' to create the distributable archive. I was hoping for a one-command solution for each, or should I just script it?

Not sure what you mean by respective local folders about "dev-deploy" but this sounds like what mvn pacakge is doing and "bundle" indeed sounds like a maven assembly.

I guess that we are talking about the Integration Engineer's tasks here. As you didn't explain what the "bundle" contains exactly, what the target application server is (my understanding is that you are using JBoss for QA/production too but, again, this is a guess), if this bundle has to be deployed automatically, it's hard to imagine all solutions and/or alternatives to antrun. But indeed, to copy/move/unzip/whatever the assembly, the maven antrun plugin is a candidate.
Finally, since the type of assembly may differ depending on who invokes it, it doesn't seem wise to bind assembly to the build lifecycle, not so?

I was hoping for a one-command solution for each, or should I just script it?
My understanding was that the Integration Engineer was building the bundle. Why would a developer need the bundle? This is confusing... Anyway, I don't really need the details to think of an answer. You could actually declare the maven assembly plugin into specific build profiles, one for development and one for integration, and bind either the single or the directory-single mojos to the project's build lifecycle in each profile. This would allow to use only one command and avoid any scripting (really, don't go this way).
