Maven project import [message #1749416]

I have simple maven project consisting of a single java file and a pom.xml - I have them in a folder. Using Mars 4.5/Jdk8.
I do a File -> Import -> Existing Maven Project- point to my folder. Eclipse does its thing and creates a project with some default (complex) project file structure (I am unable to edit it Confused

).
I see my java file in the file structure (but not in the /src of eclipse). after much doing (open/new (etc etc) ) I am able to 'somehow' compile my java class.
But I cant run it Embarrassed

If I try run as Maven project - it gives error:
[ERROR] For more information about the errors and possible solutions, please read the following articles:
[ERROR] [Help 1]
MAVEN/NoGoalSpecifiedException
What is this? Crying or Very Sad

If I try run as Java :
Error: Could not find or load main class Mad

I of course do have main method in my class

I thought this would be easy Surprised

This problem was finally solved by conforming (submitting) Smile

to the default file structure of the eclipse/maven project. I re-created the file structure (as original/default) put/copied my .java and .classes in those directories - it ran fine finally.

I could see this problem when I opened the .classpath file - it had the original /classes and /src directory and not he one I had edited in eclipse (as I indicated in my Question). Even though I was actually successfully compiling into my /classes.
I would certainly not expect this behavior, there is clear edit option for /src and /classes and it should take effect- but maybe not. Confused

So long story short it finally worked after much frustration and effort and loss of a couple of days Mad

(And I just had exactly one java file to compile and run - wondering how much pain would be if I had a few more).

It's hard to imagine what was going on without seeing the exact file structure you were trying to import, and the contents of your pom.
