Intellij idea cannot resolve anything in maven

Question

I just imported a project with pom.xml, but the IDE didn't resolve anything in maven dependencies.

Anything defined in pom.xml dependencies when import in code raise an error cannot resolve symbol xxxxx

But mvn install will work, I try import the dependencies in Project Settings/Libraries in .jar files, then it works, but could the ide resolve libraries defined in pom.xml? i don't want to do that everytime.

Additionnal info:

IDEA version: 12.0.3, OS : windows 7, reimport does not work, maven version : 3.0.4, maven dependencies does not exists under Exernal Libraries.

There are no exceptions in idea.log...

IDEA version? Any related exceptions in [idea.log](http://intellij-support.jetbrains.com/entries/23352446)? Maven version? What OS do you use? Does Reimport button work in the `Maven Projects` tool window? Do you see the dependencies under the `External Libraries` node in the `Project View`? — CrazyCoder, Mar 31 '13 at 07:43

Try [IDEA 12.1](http://confluence.jetbrains.com/display/IDEADEV/IDEA+12.1+EAP), enable **Maven 3** in `Settings` | `Maven` | `Importing`, network configuration [may also affect it](http://intellij-support.jetbrains.com/entries/23403071). — CrazyCoder, Mar 31 '13 at 08:19
thanks for your answer, it works now, but there is still a problem: the dependencies which scope=system will not be deployed when run in tomcat. — Burst, Apr 19 '13 at 14:20

In IntelliJ 12.1.4 I went through Settings --> Maven --> Importing and made sure the following was selected:

Import Maven projects automatically
Create IDEA modules for aggregator projects
Keep source...
Exclude build dir...
Use Maven output...
Generated souces folders: "detect automatically"
Phase to be...: "process-resources"
Automatically download: "sources" & "documentation"
Use Maven3 to import project
- VM options for importer: -Xmx512m

This took me from having a lot of unresolved import statements to having everything resolved. I think the key here was using Maven3 to import project... Hopefully this helps.

Thanks, I had a problem where Maven 3.0.5 (bundled) would result in no maven dependencies being imported, but updating to use 3.3.9 allowed all the dependencies to import correctly. – Matthew Buckett Nov 28 '16 at 15:23
Not sure why IDEA doesn't have context menu similar to Eclipse to build maven based project. With version 2017.2 you need to do File > Other Settings > Default Settings > search for maven in search field. IDEA has really bad UX compared to Eclipse – vikramvi Aug 29 '17 at 13:32

I ran into this issue when using IntelliJ 14's bundled Maven 3 instance.

I switched to using my own local Maven instance, via:

Settings -> Build, Execution, Deployment -> Build Tools -> Maven -> Maven Home Directory

Then added the path to my locally installed instance.

This got the dependencies to magically appear.

I have tried several options, but this one finally solved my problem. I re-imported the project by following these steps in IntelliJ:

File -> New -> Project From Existing Repositories
Choose your project from 'Select File or Directory to Import'
In the next screen choose 'Import Project From external model', and choose 'Maven.
In the next step, click the checkbox 'Import Maven projects automatically', (that solved my problem)
Finish up by choosing profiles if necessary

For me re-importing maven projects did not solve the issue for an existing projects.

Close IntelliJ
Open the same project
When the project loads, at the lower right you can see a pop up saying non-managed pom.xml file found, if you click on it a new pop up will come, saying add as maven project, click on it, and done.

I had the very same problem as author!

To solve my issue I had to add Maven Integration Plugin: File | Settings | Plugins

Like this:

Maven Integration Plugin

After that Intellij downloaded all the dependencies from pom.xml file.

Now if I want to create a project based on maven model, I just choose Open on the first Intellij window and choose the pom.xml file:

If you imported your maven project in IntelliJ and there are errors because of maven imports not getting resolved, it maybe because of the custom maven settings.xml you may be using. I tried overriding it in the Intellij default maven settings but it did not help. Finally I had to keep it in ~/.m2/settings.xml and then IntelliJ finally honored it.

It seems to me that solutions to this problem is plenty and all look a bit like magic. For me, invalidation of caches, re-importing or anything else already mentioned was not working. The only thing that helped was (without re-import) go to Maven settings, uncheck automatic importing and re-check it back.

Okay I was facing this problem for days. Was trying to import POI library and Simple JSON library, I tried all the proposed answers and solution nothing worked. In the end the solution for my case was quite simple

I just needed to add the following to my module-info.java file after putting the dependencies in my POM file :

 requires poi.ooxml;
 requires poi;
 requires json.simple;

so I think because my project was in a package in a module I had to do this to let the system knows that these imported libraries will be used. so simple put the library name after require in your module-info.java file

Hope it works for you

Keep in mind that IntelliJ adds your local Maven installation's classes to its own classpath, so keep it up to date.

In my case IntelliJ tried to call method org.eclipse.aether.util.ConfigUtils.getFloat(). This caused a java.lang.NoSuchMethodError, because my years old Maven version didn't contain this method yet. Due to the exception IntelliJ stopped resolving dependencies.

After updating Maven, you have to change the "Maven home directory" setting in "Build, Execution, Deployment" -> "Maven". After that you must restart IntelliJ, because the classpath of IntelliJ's JVM won't change while running.

It took me some time to solve this problem, as I didn't expect IntelliJ to use the classes of my local Maven installation. I thought it uses it's own bundled JARs. So hopefully this information is helpful for others.
