Can not download sources with Intellij Idea community 12.1.4 and maven 3.0.5

Question

I click "download sources and documentation" in Intellij Idea Community Edition 12.1.4 and get error that sources can not be downloaded. But when I try:

mvn dependency:sources

All sources are downloaded.

What is the problem?

P.S. I have checked that Idea use the same maven that use in console. There are not any "off line" mode buttons triggered in Idea.

Try to get more information from your IDE. The error "sources can not be downloaded" isn't helpful. — Aaron Digulla, Sep 13 '13 at 07:41
It might be worth looking what .IntelliJIdea12\system\log\idea.log says when you attempt to download a source. Do you need to setup a proxy in IntelliJ so that it can download sources from external maven repository ? — Ashutosh Jindal, Sep 13 '13 at 11:15
.IdeaIC12\system\log\idea.log does not contains any error or log information about error. I checked it after get an error and no thing changes. What do you mean by proxy issue? dependency:sources work correct but I did not configure any proxy with maven. Where I can see maven configuration about that and where I must put/copy analog configuration parameters to intellij idea? — Cherry, Sep 18 '13 at 12:04
Please mark ingara's answer as correct. Confirmed with IDEA 13.1.3 — Leszek Gruchała, Jun 04 '14 at 13:55

In Intellij 2017.x, 2016.x, 15.x, 14.x the given solution does not work as the option is removed.

The problem can be solved by changing JDK for Importer to a latest JDK instead of User Internal JRE which was 1.6.0 by default on Mac

The setting JDK For Importer can be found in:

Preferences -> Build, Execution,Deployment -> Build Tools -> Maven -> Importing

It worked! All is right with the world again. Thanks! – Les Hazlewood Nov 19 '15 at 19:49

Because I'm behind a proxy, this worked for me due to certificates I had added to the `keystore`/`truststore` of my manually installed JDK/JRE. – user909481 Apr 18 '17 at 07:05

I had to switch to my own Maven home directory instead of using the bundled one and click on "Re-import" for it to work – Sonata May 17 '17 at 12:51

Running IDEA version 12.1.6 and I have the same issue.

When I uncheck the following option it does work:

Settings > Maven > Importing > Use Maven3 to import project

Confirmed, works on IDEA 14. Thank you, @ingara, that would have taken a long time to find. – Jeremy Chone Nov 27 '14 at 20:05
@EugeneEvdokimov Where is this setting for IJ14? the settings completely changed. – WestCoastProjects Jan 27 '15 at 08:12

search for "maven3" in settings and you will find it. – ingara Jan 27 '15 at 08:23

At least in IntelliJ IDEA 14.1.2, this option seems to be gone. – stuXnet May 19 '15 at 07:33
In 1.4.3, I had my settings to use my own install of Maven (3.2.3) and this would not work. By switching to the bundled version of Maven 3, it started working. – cbmeeks Jun 19 '15 at 14:14

Hello "me" from 2015! It's 5 years later and I still have the same problem with the newest version of IntelliJ. Why am I still using it? – cbmeeks Sep 11 '20 at 15:42

I had the same issue with IntelliJ IDEA 2016.1.3 and Maven 3.2.1. No solution mentioned here was working. In my case a newer Maven version fixed the issue. With Maven 3.3.9 IDEA can now download the sources.

I am using IntelliJ IDEA community version 2016.2 and also maven 3.3.9, but it is still not always working. When I hit "Download Source", status bar shows "Downloading maven sources", but after download is completed, it doesn't jump to the source code. I hit "Download Source" once again but remains the same. I have to restart IDEA to make it work. – Bruce Sun Aug 01 '16 at 04:41

Fixed it for me, I changed the bundled maven which was at version 3.0.5 to version 3.3.9 and it worked. – jgeerts Sep 01 '16 at 14:19
Worked for me as well after I switched to the version that is maintained by brew, which is 3.3.9 as of today. I had to restart IDE to make sure it works – Maksim Sep 19 '16 at 18:49
In my case I had to change "Maven Home Directory" in IDEA settings. It was pointing to the old version that didn't exist. – Slava Semushin Sep 23 '16 at 21:25

anything's already in the former answers...

download sources in your repo mvn dependency:sources
F4 on the class you want to check the sources out
locate the source jar in your local repository

maybe it is not a full IDE solution, but hope it solves your issue

In some reason clicking on "Download Sources" in IntelliJ didn't open the sources for me automatically, so clicking on "F4" opened the sources, thanks. But it's weird that previously I didn't need to press F4... – AbstractVoid Mar 16 '21 at 17:13

Had the same issue with IntelliJ 2016.2.4. As user526177 posted udating the Maven version fixes it but for my needs switching to the bundled Maven 2 was just fine and fixed the issue.

Switching to Maven2 (bundled) was the only thing that worked for me... with latest Maven installed (Maven 3.3.9) and IntelliJ Ultimate 2016.3.2. – Renato Jan 10 '17 at 14:48

I use IDEA 2017.1.3, I just change the Maven home directory option(Preferences -> Build, Execution,Deployment -> Build Tools -> Maven -> Maven home directory) of default Maven 3 to Maven 2, I believe it's the same solution for newer version of IDEA just like the selected answer. And it works for me.

I had this issue, and sources weren't being downloaded since I needed credentials from my project's specific settings.xml.

To fix (Intellij 2018.1.2):

File -> Settings -> Build, Execution, Deployment -> Maven

and provide the appropriate settings.xml in the 'User settings file' section

A custom settings.xml was my problem too. Once I removed it (temporarily), intellij was able to download source documentation. – jmrah Jun 13 '18 at 14:21

I changed the java version in pom.xml to match my jdk's version and it worked for me.

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>

     <!--earlier this was 1.8-->
    <java.version>10</java.version>

</properties>

It's necessary to check availability of repositories.

For example, if you use corporate repository but don't use VPN just right now. In this case maven can't download sources (of open-source project) if one of your repositories isn't accessible.

You can comment specific <repository> in your pom.xml file.
