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.
I am developing an idea plugin, and it is an intellij idea project.
I want to use gradle to manage the dependency.
How to config?
There is now a Gradle plugin for building IntelliJ Platform Plugins. In order to use it, you will need to add the following snippet to your build.gradle file.
plugins {
id "org.jetbrains.intellij" version "0.0.31"
}
apply plugin: 'org.jetbrains.intellij'
For more information, please see this guide to help you get started.
Ok, there are multiple ways to create an IntelliJ project, "templates" if you like, and unfortunately you can only pick one of them (IntelliJ plugin or gradle).
Thankfully, it's easy to configure a project for gradle in IntelliJ.
First, create a new project from the IntelliJ Platform Plugin template. You don't need to choose any Additional Libraries and Frameworks. This will give you a project structure including META-INF/plugin.xml and the Project SDK should be something like IDEA IU-129.451.
From here, simply create a new file named build.gradle at the top level of your project, including for example this line:
apply plugin: 'java'
Now, close the project. You can now use File -> Import Project..., choose the build.gradle file that you just created, and import the project. Accept the defaults for importing and hit OK.
The project is now opened with both gradle and intellij plugin enabled!
Notice that the source root src has disappeared and you will need to right click on src in the Project pane and select Mark Directory As -> Source Root.
To prepare the plugin for deployment, there is still the menu option in the Build menu for that - if you want to automate that part via gradle, good luck and please let us know how it's done ;)
I build in maven multiple projects (let's name them A,B,C). Project A uses .jar of project B which uses .jar of project C.
I am modifying the code of all A/B/C projects, (A is MVC app, B are business services and C is some shared layer).
The thing is, in Eclipse/NetBeans I can see all of them at once and it's comfortable to modify them. In IDEA though, I have to open 3 instances (or n instances) of IntelliJ IDEA.
Am I missing something? Is there better approach when using IntelliJ? This is the biggest downside of IntelliJ for me atm.
I think this has improved with recent versions of IntelliJ. In my current version (12.0.2), you can add any number of separate Maven projects to the same "workspace".
The simplest way I've found to do this is to click the little + icon in the "Maven Projects" window (View > Tool Windows > Maven Projects) and then select the additional pom file you want to import.
Step 1: open "Maven Projects"
Step 2: select the project you want to import:
Prequisite
Having all the related projects in the same root directory
can be helpful.
Steps
1) First you create a new Empty project
2) Then you select the root directory of all your projects.
This will create a empty project, with a .idea directory that will simply remember the module organisation we are about to do in the next step
3) Then, in the next window, you import the different projects as modules
4) In the next window, to import each project, simply double click on the build.gradle, or pom.xml
The project will be imported as a new module.
5) Done, you now have all your projects as modules, opened on the same IntelliJ project
Yes, your intuition was good. You shouldn't use three instances of intellij. You can open one Project and add other 'parts' of application as Modules. Add them via project browser, default hotkey is alt+1
In IntelliJ 14.1.2, I did it like following:
Select File->Project Structure->Modules.
Select + and Import Module and select the directory of your project(or directory where pom exists) and click OK.
Follow through the next flow of screens and after you click Finish, you should see the project alongside your existing one.
None of the solutions worked for me, since I am not working on Maven projects. There is a simpler solution. Go to:
File->Project Structure->Modules.
Instead of adding module, simply click the third option (copy). Browse your local directory and select the project you would like to add. Module name will resolve automatically. That's it.
Update: When you want to reopen to project with multiple sub-projects, in order to avoid re-doing steps as described above, just go to
File->Open Recent->'Your Big Project'.
Since macOS Big Sur and IntelliJ IDEA 2020.3.2 you can use "open projects in tabs on macOS Big Sur" feature. To use it, you have to enable this feature in your system settings:
System Preferences -> General -> Prefer tabs [always] when opening documents
After this step, when you will try to open second project in IntelliJ, choose New Window (yes, New Window, not This Window).
It should result with opening new project in same window, but in the new card:
To expand #Neo answer:
after choosing your directory. select import module from external model and choose your model (maven in this case).
Then check keep project files option from next dialog. It will keep all files in original directory.
Your final project structure would be something like this.
Now you can add your module as dependency to other module's pom.xml and if you change the source code of your dependencies, Intellij takes care of updating your project (there is no need to run mvn build manually for dependencies)
new empty project
File -> New -> Module from Existing Sources
For who uses Gradle can also avail the same:
Go to:
1. View --> Tool Windows --> Gradle
2. Click on the + button and add your build.gradle file
Open preference -> appearance & behaviour -> System settings -> select (open project in new window) then apply.
Then you could open and edit multiple projects.
You can use Armory plugin which makes switching between projects comfortable. The default shortcut for Project List is Alt + A.
By default currently opened projects are displayed at the top of this list (with bold style).
Use the button for the add maven projects and go inside the folder of the project. Then, select the pom.xml file and add them in the IntelliJ.
Press "F4" on windows which will open up "Project Structure" and then click "+" icon or "Alt + Insert" to select a new project to be imported; then click OK button...
To Intellij IDEA 2019.2, F4 + click on module, click to + for add any project from your HDD, above this menu yo can edit the IDE with you create the project and more options, very easy
For people not using maven to build and wanting to add a new project (I am using intellij 14.1.3):
Right click the top level folder in the project view, select new ->
Module
Name the module the same name as the project to be added
From the top menu select File->New->Project. Enter the same name as
the new module, same folder locations as well.
Open the Project, and wait for intellij to create the project
structure.
Close this new project, and open the original project the module was
added to in step 2
Depending on your builder, additional steps will be needed to add it to the build process.
For SBT, and in the top level project I modified the Build.scala file to aggregate the new project, and added the project in the SBT projects window. More info on SBT multiproject builds: http://www.scala-sbt.org/0.12.2/docs/Getting-Started/Multi-Project.html
"IntelliJ IDEA 2022.1.1 (Community Edition)" you have to navigate
To Add Exiting Module to same window navigate "File -> New -> Module from Existing Sources" then it will allow you to select pom.xml and then click "Create" button next window then project will be added to your current workspace.
Note :: Who ever switches from Eclipse to Intellij this is the first problem
Assuming they are under the same folder, click File-Open File or Project-<parent folder>.
you can use import module option which will open it just like eclipse in the same navigator.
For IntelliJ Idea 2021.3.3 users, The below solution didn't work for me, although I was selecting my project main folder, I've gotten only the main and test folders imported!
Peoject Structure => Modules => Import module
The solution is:
view => tool Windows => Maven => click the + icon => add the project POM.xml file
I am new to maven and did not understand how I could work with local maven project added through Viktor Nordling's answer and still have a proper dependency in pom.xml file. The answer is simple: intellij first looks at your locally added module and if it doesn't find one it goes to get the project remotely. You can check this by looking at "external libraries" under your project browser when you add or remove maven module.
Hope this helps anyone.
As of release 2019.2, this is as easy as File->Attach Project.

After importing project into IntelliJ, Go to pom.xml of each module -> right click -> Click on Add as Moven Project. It will add the module as Moven project, do this for all the modules in the Project. Refer this
I'm having trouble understanding how to get repositories in the "Indexed Maven Repositories" list of the IntelliJ IDEA.
In one my project I have two repos in this list: one local and one (main) remote (see attached screenshot below). And in other project (created using AppFuse template) I have only one (local) repo in list.
I'm tried to add the repos in pom.xml file and in settings.xml file, but the repos did not appear in this "magic" list.
And this means:
I can't see artifactId and versions of artifacts in dropdownlist (Ctrl+SPACE)
IDEA can't find the necessary artifacts (or his versions). It is looking only in my local repo
Version of IntelliJ IDEA: 11.0
Version of Maven: 2.2.1
This list is updated automatically from the repositories specified in your pom files (or inherited from parent project's pom and settings.xml).
If you open a project that has some additional repositories specified, you'll see them in this list and will be able to update the indices.
You can manage these settings by editing your settings.xml file of the project
Open the Project file list (Ctrl-1)
Find your main parent pom.xml file
Right click on it Choose Maven -> Open 'settings.xml'
As you can see it is a local copy of settings.xml file for your project.
There is you can add/remove active repositories of the project.
Look at the settings->repositories manual for details.
I had a related issue where I changed the repository in my settings.xml but the Indexed Maven Repositories list was still pointing to the old one. In order to get the maven build to look at the new one I had to run mvn idea:idea on the project
I recently set up a j2ee development environment under Ubuntu: Eclipse (Helios) with the maven plugin (m2eclipse).
When I try to create a maven project, it tells me to select an "Archetype".
Then, I select an Archetype with a GroupId : "org.apache.maven.archetypes" and the
ArctifactId : "maven-archetype-quickstart" (I tried also with the followinf artifactIds
"maven-archetype-mojo" "maven-archetype-j2ee-simple", ....).
Then, it creates a standard maven directory structure.
I added the "javax.perssitence" Maven Dependency that load the "persistence-api-1.0.jar".
But I can't find the "src/main/ressources" and "src/test/ressources" to access to the "persistence.xml" file.
Is it a bug? Should I create it manually?
Thank you for your answers ;)
No, it's not a bug, just create them manually and update the project configuration under Eclipse (via right-click on the project and Maven > Update Project Configuration)
