    Hi,

    I often have the same error as described here.

    I used to solve it by changing SpringBoot ‘starter parent’ artifact version to 2.1.4-RELEASE.

    This workaround doesn’t work anymore and I didn’t find any version of the above artifact that seems complient with the libs I need for my project.

    I certainly should change the m2e connector for MavenArchiver to 0.17.4, but this version seems not complient with MyEclipse installed components.

    What should I do to make this unknown error vanish ?

    Thanks

    Frédéric,

    Thank you for pointing us to the s/o post and the corresponding bug, saved us some time.

    1) Yes, you won’t be able to install the m2e update into MyEclipse as there are hard constraints internally which will cause conflicts, as you have already seen.

    2) Here’s a workaround that should work for you, until we fix this in the next MyEclipse release. We tested this internally and it fixed the issue for us:

    a) Download attached zip file.
    b) Shut down MyEclipse.
    c) In your MyEclipse installation’s plugins directory, you will find a file named: org.sonatype.m2e.mavenarchiver_0.17.2.201606141937-signed-20160830073346.jar – make a backup of this file.
    c) Unzip the zip into the plugins directory, it will overwrite the above file.
    d) Start MyEclipse.

    So that you understand what is happening, we’ve just taken the 1.7.4 plugin and renamed it to have the same name as the 1.7.2 version already used in MyEclipse. Please let us know if this fixes the issue for you. We’ll ensure that this fix is part of the next MyEclipse update.
