What is a working directory in Intellij IDEA - intellij-idea

I created a Maven project and imported it in Intellij IDEA.
In a run configuration, there is a field "working directory", which points to the root of Maven project.
If I change this folder, it doesn't seem to affect anything. So what is it?

This is the directory that is set as the Java user.dir system property. If you have any code that creates relative files or directories, it will be relative to this directory. So for a well designed application (i.e. resolves resources from the classpath and is configurable for output directories) this will not be a factor. There is also some importance to this value in maven projects, especially multi-module maven projects. This directory specifies the directory IDEA will read the POM from.
If you are unflamilar with what the Java user.dir is, there is some discussion available here and in the class level Javadoc for the File class.

In addition to answer given by #Javaru if you want to update or view your working directory in IntelliJ IDEA go to:
Run | Edit Configurations | Configuration Tab | Working Directory

From the IntellJ help Run/Debug Configuration: Maven
Working directory Specify the path to the Maven project file pom.xml.

Gradle dist folder on IntelliJ classpath

We have a project which we build with gradle. We use IntelliJ as our development environment.
We have some resources we want to keep outside the JAR and so we have put them in the src/dist-folder. This works fine when running the application from the command line, but not so good when we want to debug from IntelliJ.
We could put a runtime-dependency to src/dist, but then we end up with files inside our lib-folder in the generated ZIP file and that's not what we would like to have.
Bottom line: how can we keep some resources outside the JAR (in src/dist) and also on the classpath of IntelliJ (as generated by Gradle; I don't want to have to add things manually to the IntelliJ classpath). The directory structure in the resulting zip should be something like:
root
|
|- config/*
|- css/*
|- lib/*
It seems that this question describes a similar problem, but the solution in addition #4 still mentions that no solution was found to correctly get the resources on the classpath of IntelliJ:
Gradle build file with conf folder with properties not in jar but on classpath
The solution I've used in a similar situation is to:
Use the Idea plugin in gradle rather than relying on the IntelliJ support.
Once that is working you can tweak the source path that IntelliJ uses in the gradle file itself

maven build - IntelliJ

I am trying to create a jar in IntelliJ through maven clean-compile-package. Build is sucessful but I am not getting class and packages in tha jar. Please help! I got below warning in logs:
[WARNING] JAR will be empty - no content was marked for inclusion!
maven project have default standard directory layout its documented here
if you not followed them or moved folders around, maybe changed output folder or similar action was taken, maven can't correctly decide how to include your class files.

How to refresh lib folder when update pom.xml?

I create a simple sample Spring MVC project, where IntelliJ 14 by default generate a pom with
<properties>
<spring.version>4.1.4.RELEASE</spring.version>
</properties>
I change it to
<properties>
<spring.version>3.2.0.RELEASE</spring.version>
</properties>
and choose Maven -> Reimport, I can see the dependencies are downloaded to my local .m2 folder
However, when I expend lib folder, all dependencies stays with previous version:
How can I get the latest dependencies showing in \lib folder? I tried to synchronize current project, but it doesn't help this matter
UPDATE
here is my maven setting
UPDATE 2
I forget some detail, which is I create a Spring MVC project in the beginning(so I think it may not be a maven project at the moment), then I right click pom.xml and set current project to maven project.
So I think the jar files listed in \lib folder may be downloaeded via intellij for Spring MVC application, however when I set current project to maven project, it does not remove or update the jar file under the \lib folder.
You should do:
1. Choose menu File \ Project Settings..., In section Build, Execution, Deployment \ Build Tools \ Maven \ Importing, check Import Maven projects automatically. It means IntelliJ IDEA will Synchronize Maven project model and IDEA project model each time when pom.xml is changed.
2. Try closing project, restart IntelliJ IDEA, then reopen the project.
3. Check your internet connection.
IntelliJ isn't shouldn't be looking there for your Maven project dependencies. It is should be using the libraries and resources in your .m2 directory instead.
Mind you, I've left those comments struck out on purpose; depending on your configuration, you may accidentally be doing that.
This is a picture of what the Dozer project looks like. It's a Maven project which I cloned a ways back to see how it worked.
You're going to have to check your Project Structure (Ctrl + Alt + Shift + S) to ensure that the libraries that are coming through are prefixed with "Maven:".
If they are, then the files in your lib folder aren't being used by your project.
In all actuality, those are your global libraries (which you can also find under Project Structure > Global Libraries). Any project has access to them.
If that's causing a conflict, consider deleting those JARs from your global libraries. If you need them for another project, consider adding it to the project's local libraries instead.

Apache Ivy Best Practices

Hi I'm reading up on Ivy for the first time and had a few quick questions:
Need confirmation: the IvyDE plugin is used to configure just the ivyconf.xml file for all workspace projects, correct?
Where does this ivyconf.xml live? I'm running Windows 7 and can't find this hidden .ivy directory anywhere!
Where do you usually place a project's ivy.xml and other xml config files?
Thanks for any nudges in the right direction!
IvyDE allow you to resolve dependencies per project. You could use separate ivyconf.xml in different projects.
You could place ivyconf.xml (or ivysettings.xml) where you want. You could use one per project (as I do) or one for all projects (as I did before).
Usually I put ivy.xml beside Ant's build.xml in the root of my project. But ivysettings.xml I put in project/etc/ivysettings/ directory.
My team uses a separate build project in Eclipse that stores the ivysettings.xml file. The IvyDE plugin provides the Ivy dependency container that the Java projects can use. IvyDE can optionally allow inter-project dependency resolution, but this is off by default.
I'd suggest changing the order of classpath entries in the Ivy Classpath configuration to lexical, otherwise it shows dependencies in the order of the ivy.xml file.
Each project should have their own ivy.xml file - we also follow the same pattern as Alexey uses of using the project's top-level directory.
I've never used an ivyconf.xml file - a quick google suggests this is an alternative (older, deprecated?) name for the ivysettings.xml file.
You will need to write your own ivysettings.xml file to tell IvyDE where your repositories are and which resolvers to use. Leave a comment if you're interested in an example ivysettings.xml file.
Which repositories are you using? Maven Central? Setting up your own repository with Nexus, Artifactory or just using the file system?

intelliJ 9 cannot find class I specify in web.xml

I am trying to get logdigger to work in my java app that uses google app engine. I have tried putting my jar files in the src/ directory, lib/ directory, and no matter what I do, it can't find the class. The only thing that it finds is the com.google.appengine stuff. I have tried messing with my dependencies and it's not working. Has anyone done this before and gotten it to work? I am not sure how to modify the classpath through intelliJ (however in the project settings I have the jars linked as a dependency under the modules section).
You probably need to look at the artifacts for your project. IntelliJ separates runtime assembly of WARs into the artifacts section. Look and see that your WAR file is assembled properly. I'm guessing that you don't put the contents of the /lib directory into the WEB-INF/lib of your WAR. The compiled output ought to go into WEB-INF/classes. All other output belongs in the root of the deployment.
