Unable to import maven project in IntelliJ14

Question

I'm trying to import the Maven projects from IntelliJ button (the one with the arrows in circle), but I get the following message "Unable to import maven project. See logs for details", as shown in the following picture

If I go into the log, I see:

I'm using Maven 3.3.3 and JDK 1.7.0_71 on a 64bit Ubuntu machine.

Strange thing, is that I can use Maven by command line. Any idea?

Answer 1

Besides all solutions above, you can try close and reimport the project from IDEA. My issue solved by this simple way.

Answer 2

For me updating it to intellij 2020 worked from 2017.3.

I had tried almost all the solutions described here, but updating intellij to 2020 just worked without doing anything.

Answer 3

I had IntelliJ IDEA 2018.2 and maven 3.6.3 couldn't work. So I updated IntelliJ IDEA to a version 2019.3 and could use maven 3.6.3.

Answer 4

This worked for me

1. Go to: File > Settings > Build,Execution,Deployment > Build Tools > Maven > Importing

2. Change: JDK for importer to your installed JDK instead of IDEA's internal JRE (Use Internal JRE from ../JetBrains/IntelliJ IDEA/jre64)

Also searching in IDEA log files helped me. I found this message:

Caused by: java.io.IOException: Cannot run program "C:\Program Files\JetBrains\IntelliJ IDEA 2017.3.2\jre64\bin\java" (in directory "C:\Program Files\JetBrains\IntelliJ IDEA 2017.3.2\bin"): CreateProcess error=2, File not found

Answer 5

Below is the solution that works the best for me:

Go to File > Settings > Build,Execution,Deployment> Build Tools > Maven > Importing :

Change VM options for importer to -Xmx4096m

Answer 6

In my case it was my firewall. I use bullguard protection btw, which is pretty strict with its firewall.

Answer 7

Below one worked for me ;

Go to File > Settings > Build,Execution,Deployment> Build Tools > Maven > Importing .

Change VM options for importer to -Didea.maven3.use.compat.resolver

Answer 8

I don't know what caused this, all i know it was very easy to fix:

1. Download maven here and extract it in a place of your choice.
2. Then, go to File>Settings>Build, Execution, Deployment>Build Tools>Maven.
3. In Maven home directory, instead of Bundled maven, point it to the folder you just created.
4. Enjoy.

Answer 9

Solved. I had to remove the IntelliJ project folder (.idea) and create a new project from the existing source clicking on the parent pom. Then, everything worked properly.

I guess that some file was corrupted.

In steps. Initially you have something like:

After deleting the .idea folder you will have:

So you close the project and start one from existing sources:

You select the pom.xml file to create the new project and oveeride the IntelliJ project if one was found.

Now you should see exactly the same as in the first picture.

Answer 10

I got into this same state (unable to import maven project) several times (i was running a load test and hitting the max number of open files on the OS, so normal file saves were erroring out). It probably is a corrupt file causing this. A computer reboot acutally solved it a few times but other times I solved it by switching to command line and running "mvn clean install"

Answer 11

In my case I'd just upgraded my OS (OSX) and doing so deleted my JDK, so Intellij was quietly failing. Following @JeanValjean's advice meant that the project was no longer loadable at all (I couldn't get to JVM preferences). Looking in ~/Library/Logs/IntelliJIdeaXX/idea.log told me the problem and deleting ~/Library/Caches/IntelliJIdeaXX and ~/Library/Preferences/IntelliJIdeaXX/options/jdk.table.xml let me open the project again and fix the path to the JDK.
