In this case m.jar was already copied into the jar for the first entry and the second one will yield the shown exception.

I wonder that it doesn't show the duplicate entry though. Normally it appears directly after the colon.

Anyways, we probably should catch this exception and tell the user to check the additional JAR contents specification.

Note: The upcoming version - the code is already available in our Subversion repository - makes the specification of additional JAR content much more convenient. After choosing "icons/000.png" as the source file, it will propose "icons/000.png" as the destination. Also note that to include all files in "icons/" you can add "icons/" as a source folder. Then the whole contents of the icons folder will be copied into the JAR.

• don't display the absolute path in the Source column, but rather display the path relative to the module directory, if the module directory is a parent
• double-clicking a row should open the edit dialog
• it's not obvious, that the right column is editable
• after clicking Edit, I've got a source-path-choosing dialog followed by the target-path-dialog - two ways to edit the same?
• btw, I've first used *.xml in the second dialog by mistake - maybe that should be prevented
• btw, the first tab is named "Geneeral" - one e too much

Yes, I also thought about that when I implemented it. I'll add a renderer for that column soon that will replace module and project prefixes with something shorter. Maybe MODULE-DIR and PROJECT_DIR or something like that. Anyways the way the table displays the data can and will be improved.

• double-clicking a row should open the edit dialog

Yes, I'll add this.

• it's not obvious, that the right column is editable

I'm searching for a way to make it more visible. As far as I know there is nothing in IDEA that I could apply here and that would directly tell users "I'm editable".

• after clicking Edit, I've got a source-path-choosing dialog followed by the target-path-dialog - two ways to edit the same?

Well not really. When you choose the source path part, you choose something that already exists. The destination part does not exist yet and therefore there's nothing you could choose from.

• btw, I've first used *.xml in the second dialog by mistake - maybe that should be prevented

That's a good point, I'll add a check that will make sure that the input for the destination is a valid path definition.

• btw, the first tab is named "Geneeral" - one e too much

Thanks.
