When I develop application in IDEA, where should I place logback.xml for it to have an effect on the application?
It seems when you run/debug IDEA doesn't make any jars and doesn't invoke Maven to build something. Does it execute main() directly from compiled *.class file? If so, where can I put logback.xml so that it would have effect?
logback.xml should be available in the root directory of your CLASSPATH. When you run your application, the full CLASSPATH is printed at the very beginning. When I put logback.xml in /src/main/resources (Maven project) it works without any problem. Also putting it in /src/test/resources with logback-test.xml name has presence.
Simply run:
getClass().getClassLoader().getResource("/logback.xml");
And see whether it returns something or null.
If you are not working with Maven project, open Project structure (Ctrl + Alt + Shift + S) and add in Modules section select folder containing logback.xml and mark it as Sources (blue icon).
For me: I simply needed to re-build the project (not just re-run or re-compile the project). Changing the src\main\resources\logback.xml did not affect logback because the class loader is picking up the logback.xml that is in the target/ folder, not the /src folder. This makes sense since target is the run environment. Therefore, a build is required to transfer the new xml file over to target.

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
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 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 .
I have a module for which I want a jar to be created. So, here is what I do:
Adding a jar artifact, using the "From module with dependencies ..." option
In "Jar files from libraries" I select "copy to the output directory and link via manifest"
Leave all the defaults.
After that I can build the jar and all the dependencies would be placed near it in the same directory. So far so good.
Now I wish all the dependencies to be placed in a separate directory near the final jar. So, I repeat the same steps, but this time I create a new directory under the node in the artifact Output Layout tab (using the "Create Directory" button). Next I drag all the dependencies onto the new folder and apply the changes.
On the surface, everything is cool - the dependencies are indeed placed in the dedicated directory, but the MANIFEST.MF file is never updated! It should reference the dependencies via the new directory. As of now, the produced jar cannot be run - its dependencies are not visible.
This is unlike Eclipse, which does make sure the manifest file is correct when exporting a project as jar.
How can I workaround this problem, given that:
I want all the dependencies in a dedicated folder.
I want to use IntelliJ IDEA
I do not want to edit the manifest file manually.
I am using the latest download of the IntelliJ IDEA for windows - 11.1.2, build 117.418
Thanks.
At the moment you have to update the classpath manually in the artifact configuration dialog so that it includes the subdirectory:
I've created an issue for this limitation, please star/vote.
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.
