IntelliJ CE is great integrating maven execution for modules.
Im using IntelliJ CE 13, and for custom maven executions i'm using the "Execute maven goal" window.
A great feature it has is it remembers all (and i mean all) of the previous executions, which is a great thing to avoid typing over and over the same command.
BUT, if anytime you type a really long command, the window gets resized to fit in the command, so it's a little bit annoying to scroll in order to view the "choose module" button.
Is there any way of "cleaning" that list of previous executions???
To the best of my knowledge, there is not a way via the UI to clear that list. You may want to open a feature request to do such: http://youtrack.jetbrains.com/
That said, there is a hack you can do to clear it (or selective items).
.idea
directory within your project
.iws
file for the followingworkspace.xml
fileworkspace.xml
file<component name="mavenExecuteGoalHistory">
/project/component[@name='mavenExecuteGoalHistory']
<option>
elements within that <component>
