This is certainly odd because I've never seen this before (I work on
Windows, Mac and Linux) and would have expected others to report it before
now. Therefore to fix this speedily we would need a recreatable testcase
that shows the problem - doesn't need to be small, just publicly accessible.

BTW, does this happen when a single developer runs the build on their own
machine (with no other builds running) or does it only occur on a build
machine that may be potentially running many builds? I ask because there's a
design issue in Maven that means the local repository is not protected
against concurrent reading/writing.

So if you have multiple builds running concurrently against the same local
repository you will see occasional failures wrt. changed files, no matter
what improvements are made to the plugin code.

if I'd been told about this sooner then possibly, but not at this stage -
unless of course this problem doesn't occur with 1.4.1 (but that uses the
same version of Bnd, so it should also behave the same)

btw, I don't see a patch attached to the JIRA issue - does the patch solve
your current build issues?

fixing this properly will require changes to Bnd and a Maven shared
component which are managed by other teams with their own release schedules
- also the latest Bnd library contains other changes, so I'd want to do lots
of testing before moving up to the new version.

we could look into doing a custom release, using patched source files to
override the classes in the original dependencies - but then I'd definitely
need access to a recreatable testcase and your patch to apply and verify the

that might be the best option for now, especially as I won't be online at
all from the 10th to 24th.

certainly the earlier I know of potential issues the easier it is to plan,
so I'd strongly encourage users of the bundleplugin to report bugs and
feature requests on JIRA as soon as possible - and if you're expecting to
move to the new release, please test against the early snapshots as much as
