This is not really a plugin but an external tool that displays a dialog to
allow you to paste in a stacktrace and have IDEA make the filenames
Internally all it does is take the contents of the text area and send it to
System.out this then appears in the idea Messages console all nicely
To add it as an external tool:
Tools | IDE Options | External Tools
Add a new Tool
Description: Hilight a stacktrace
Leave the "Show Console" option checked.
Uncheck "Synchronize files after execution"
Program : $JDKPath$\bin\java.exe
Arguments : -jar c:\hilite\HiLightTool.jar
Right-Click in the editor and select HiLite | Stacktrace
When the window opens, paste in the stacktrace from the clipboard with
ctrl-v and click done.
The window will close and the stacktrace will be hilighted in the messages
Hope this is of some use to you.
