"Delivery Failed...as it would create conflicts in the stream" How to get past this?

Hi,

I'm new to RTC.

I go to deliver a change set via the Eclipse UI and get this popup:

Delivery for component 'X'  failed as it would create conflicts in the stream. As you do not have any incoming change sets for this component, you should consider delivering all of the outgoing changes.

When I attempt to use the command line, I get a similar but different message:

$ scm deliver -c 1255

P r o b l e m   r u n n i n g   ' d e l i v e r ' :

 D e l i v e r y   w o u l d   c a u s e   a   c o n f l i c t .     R u n   ' s c m   r e s o l v e '   o r   ' s c m   c o n f l i c t s '   o r   ' s c m   s t a t u s '   f o r   h e l p   i n   r e s o l v i n g   t h e   c o n f l i c t s .

$ scm conflicts

No conflicts found.

Outgoing changeset

I could not get .jazzignore to work from the command line.

Consequently I worked around the problem by creating an outgoing changeset and dumping all my "IDE-internal files" there (i.e. the '.idea' directory)

[I'm using intellij because I need it's refactoring tools. ]

Consequently I have this other outgoing changeset. This

thanks in advance
