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

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.
