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

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.

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

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

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.

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

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.

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

I solve this by use jdk 1.8 in MAVEN -> RUNNER -> JRE .my idea version is 2016.2

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>
