I have a code in Java. It contains only *.java files in the nested directories and nothing else. I want to create a java project using it. How do I do that in IntelliJ Idea 12?
Import Project, select the directory with the existing sources (or its parent that you want to be the project root), follow the wizard steps.
More details can be found in online help.

I prefer having one IDEA project per task I'm working on. If it's a Gradle project, I can run gradlew idea to generate the project files then rename them to be indicative of the task I'm working on (so that when re-opening from IDEA a project, it's obvious what the task is and IDEA is able to list several tasks for the same Gradle project). This works well enough if it's a Gradle project, but if it's not, I'm left with using the IDEA GUI to open the project by pointing to the working directory. Is there a command-line way to generate the IDEA project files so I can rename them prior to using the GUI? Being able to do this would also obviate the need for using gradlew idea for this purpose.
Using the GUI, create the project by pointing it to the build.gradle file or project root directory. Once the project is created:
click the File menu
click the Project Structure menu item
change the Project name text value
I simply want to export my java intellij project from one pc to another, no need for git because I only want to test something on the other pc because it has more memory.
Surprisingly no information on this is available, there is information on how to export a project to a jar file, but I cannot import from this jar file. On their website : https://www.jetbrains.com/help/idea/2016.3/import-existing-sources-project-name-and-location.html they don't give any clear instructions on how to do this simple operation? how is this done?
Till version 2016.3.4 IntelliJ doesn't provide such facility.
Best way to do so would be to copy the whole directory containing your project or module. Doing this would retain all your project related settings.
With the latest version of IntelliJ IDEA, all you need to do is unzip the project in the new computer and then select Open in the IntelliJ IDEA new project wizard. Do not use the option to import the project from the zip file, as that doesn't work.
Take all directories of your project and copy them into the other computer. Launch IntelliJ and open the folder of your main directory project, that is all it needs to work (*.iml files do all stuff for you). If you don't know what directory is the main, you can close the project in your other IDE and see what paths it is catching. For example in my case:
I'm working with intellij idea but I can't see the java source files in the project tree. I see the packages, I can open it, but the class files are not displayed. Any idea? This has worked until a few days ago...
Under the intelliJ IDEA 14.0.3 community edition, upon launch I don't see my project folders. I found by going into
View > Tool Windows > Project
seems to show the folder structure.. Same as ALT + 1
Below the menubar , on the left there is a dropdown which in your case may be showing "packages" now (because you can see the packages). From the same dropdown, select "Project Files" below "SCOPES"
You need to check out the project correctly if you are checking out from SVN repo or you must not have selected correct project folder.
You can also configure your project from File->Project Structure check your Source folder is excluded or not.
Also Alt+1 will give you project structure of files in tree format
Check in "Project Structure" (ctrl+alt+shift+S) if you didn't set your source as "Excluded" (in Modules, sources).
If you are develop a maven project, you could run mvn idea:idea and then open the project in your Intellij, the source files and the project tree would become the shape you like.
I have created a new Intellij project. But I can't use the third party jars in my project. I have the jars in a directory structure as follows:
repository/commons-logging/commons-logging-1.0.4.jar
repository/commons-lang/commons-lang-2.1.jar
etc.
I want to add them just by pointing to the repository directory, but couldn't find any ways to add them.
But when I am using classes or API from that jars, the editor can't resolve the classes.
I have tried from Project Structure but can't configure it.
Go to File-> Project Structure-> Libraries and click green "+" to add the directory folder that has the JARs to CLASSPATH. Everything in that folder will be added to CLASSPATH.
Update:
It's 2018. It's a better idea to use a dependency manager like Maven and externalize your dependencies. Don't add JAR files to your project in a /lib folder anymore.
If, as I just encountered, you happen to have a jar file listed in the Project Structures->Libraries that is not in your classpath, the correct answer can be found by following the link given by #CrazyCoder above: Look here http://www.jetbrains.com/idea/webhelp/configuring-module-dependencies-and-libraries.html
This says that to add the jar file as a module dependency within the Project Structure dialog:
Open Project Structure
Select Modules, then click on the module for which you want the dependency
Choose the Dependencies tab
Click the '+' at the bottom of the page and choose the appropriate way to connect to the library file. If the jar file is already listed in Libraries, then select 'Library'.
On the Mac version I was getting the error when trying to run JSON-Clojure.json.clj, which is the script to export a database table to JSON. To get it to work I had to download the latest Clojure JAR from http://clojure.org/ and then right-click on PHPStorm app in the Finder and "Show Package Contents". Then go to Contents in there. Then open the lib folder, and see a bunch of .jar files. Copy the clojure-1.8.0.jar file from the unzipped archive I downloaded from clojure.org into the aforementioned lib folder inside the PHPStorm.app/Contents/lib. Restart the app. Now it freaking works.
EDIT: You also have to put the JSR-223 script engine into PHPStorm.app/Contents/lib. It can be built from https://github.com/ato/clojure-jsr223 or downloaded from https://www.dropbox.com/s/jg7s0c41t5ceu7o/clojure-jsr223-1.5.1.jar?dl=0 .
In our project we are using jaxb2-maven-plugin to generate Java source code from XML Schema, which causes that our Maven module requires additional source code directory (in our case target/generated/main/java). Up to date I've been using Eclipse and maven-eclipse-plugin to import all the projects into Eclipse workspace. The plugin is (somehow) able to add the directory with generated source code automatically to Eclipse' .classpath file.
Recently I try to switch to (play with?) IntelliJ IDEA 9 (so I am a newbie in this environment) and I've noticed that additional source directory is not added during IDEA's importing process...
Is there any way I can configure IDEA/Maven to make importing directory with generated source code automatically?
The convention with Maven is to generate code in target/generated-sources/<tool>, for example target/generated-sources/jaxb2
Follow this convention and IDEA will add the folder as source folder (see IDEA-53198).
Generated code, using jaxb2-maven-plugin, was missing for me in Intellij 2017.1 whereas Eclipse Neon created it.
Fixed it from context menu of module by selecting 'Maven -> Generate Sources and Update Folders'.
Try with maven-jaxb2-plugin. If it does not work then it's IDEA problem.
In Maven you can add new source roots per configuration. Maven plugins can do this programmatically. This is for sure the case with maven-jaxb2-plugin. Then, if IDEA does not recognize it, then it's a problem on that side.
You can use the Maven Build Helper Plugin. It is located at http://www.mojohaus.org/build-helper-maven-plugin/
It allows to configure additional source roots. And the maven integration of IntelliJ will add the new source root. We are using this feature in quite a few builds and it works just fine. Tested with vers. 13 of IntelliJ IDEA.
