No problem at all :)
Thanks!

Hello again,
I have provided additional information and another patch for review plus
regression tests pull request.
Can you take a look at it when you have some time?


I also submitted another bug with a patch on a different topic:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=431587

    Hi,
    I probably confused you with my explanation.
    I submitted https://bugs.eclipse.org/bugs/show_bug.cgi?id=431580
    with a description that probably makes more sense.

    Best regards

        General m2e contribution requirements are explained in [1]. Note

                 Oh and I mean that only in the context of project name

                 do understand that this might cause troubles or at least

                 In our case such properties are empty most of the time.
            There is a
                 special build profile that does specify it, but it is
            very rarely
                 used within eclipse, it is for headless jenkins build.

                     Well, actually, I thought about making it to treat
            placeholders
                     as plain text or maybe event better ignoring them
            completely.
                     At the moment import just fails with an exception.

                         This is not really supported by m2e because
            ${properties}
                         are expected
                         to change during development, and cannot be
            relied upon to
                         establish
                         project groupId/artifactId/version required for
            dependency
                         resolution.

                         Even if property values do not change, they can
            be inherited
                         from
                         project parent hierarchy, which I don't think
            is available
                         during
                         import. So the fix is much more involved than
            just ${property}
                         expansion, if I am not mistaken. If you think
            you can
                         implement this
                         without causing significant performance
            degradation, please
                         submit the
                         patch to Gerrit and we'll discuss details there.

                             Hi,

                             There's a small problem with Import Maven
            Project action
                             when using
                             [groupId], [artifactId] and/or [version]
            project name
                             templates for
                             projects that have property placeholders
            withing
                             respective values.

            ProjectImportConfiguration#____getProjectName() uses those


                             values as a
                             replacement value for String#replaceAll(),
            and it fails
                             whenever it sees
                             '$' (which is part of ${...}), since this
            is a reserved
                             character for
                             group backreferences.

                             In particular, we have a profile-dependent
            property
                             within artifactId on
                             some of our artifacts (bad practice, but I
            have no
                             control over that,
                             unfortunately).

                             It should be pretty straightforward to fix with
                             Matcher.quoteReplacement().

                             I can submit a bug and attach a patch that
            fixes it.

                             Also, as
            ProjectImportConfiguration#____getProjectName()


                             is deprecated, is
                             there a replacement method somewhere that
            might inherit
                             same problem?

                             Thanks in advance.
