Unable to load intellij module when using mvn idea

问题:

I am using: IntelliJ IDEA 11.1.3 (Community edition) and Maven 3.0.4.

The project contains several modules, one of them creates a war-file. When I use "mvn idea:idea" IntelliJ is unable to load this module for some reason. The error message is: "10:40:04 AM Error Loading Project: Cannot load module"

I can fix the problem by manually importing existing module, but this is a very annoying problem. Does anyone know why this happens, could it be a maven or intellij problem? Is it something I can do to fix it?

回答1:

Just open the project by pointing to the pom.xml file. Skip the maven-idea-plugin, it is obsolete.

The maven-idea-plugin has not been active since 2008.

回答2:

mvn idea:idea is obsolete and should not be used, it's known to cause problems. Just open pom.xml directly from IDEA and it will import the Maven project.

To import with more options create a new project from the external Maven model.

回答3:

mvn idea:idea is no longer used. The official page for the plugins usage states Apache Maven IDEA Plugin (RETIRED).

You can directly do File -> Import project and select pom.xml file.

I was getting the same error on Mac (i.e. "Error Loading Project: Cannot load module") too. This is how mine was fixed.

1. Tap with two finger on the Trackpad (kind of right click in away) on pom.xml file.
2. Go down in the menu to "Maven" and then select "Reimport".

That made it work for me, hope this helps you too :)
