Anything defined in p

Answer 1

I have encountered this problem，idea cannot download all dependent jar packages using maven,i just tried the following operations:

 mvn -U idea:idea

then all the dependent jar packages are download from the maven repository

Answer 2

I was also getting this error because the project imported main and test folders as modules. Click on Project --> Press F4 --> In Module settings, remove main and test folders and the make the project again. Problem will be resolved.

Answer 3

1. Close IntelliJ
2. Open the same project
3. 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.

Answer 4

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.

Answer 5

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.

Answer 6

I was getting this error because my project was not setup correctly. It had imported main and test folders as modules. When I deleted the 2 modules (but retained them as source and test folders), my code started compiling correctly.
