I have a custom classpath container initializer that parses an xml file
and populates a custom classpath container with jars contained in this
file (lib dir substitute). Lots of things can go wrong during
getClasspathEntries.
When things do go wrong I want to let the user know so that they can fix
the problem(s). I log the exceptions to the error log. This works.
However, I need a way of notifying the user so that they know something
has failed and to check the error log for details.
I have tried using error dialogs: no good, because the getClasspathEntries
method of my initializer may be called whilst eclipse is booting up, and
is in headless mode.
I have most recently tried using problem markers. However, this is failing
too with the following error: "The resource tree is locked for
modifications". (Full stack trace is below.)
How am I to proceed? Can anyone provide some advice?
Thanks,
Miles
