Maven assembly plugin warning "The assembly descriptor contains a filesystem-root relative reference"

Question

Starting from some assembly plugin version maven builds issue the following warning:

[WARNING] The assembly descriptor contains a filesystem-root relative reference,which is not cross platform compatible /

Is there any recommended ready-to-use solution for this? Direct googling provided me with lot of trash and no real help. Re-check of Maven assembly plugin help did not provide answer for me, maybe someone else has better search skill and can help.

UPDATE

Yes, this is probably because of Linux-like outputDirectory but how should I rewrite this to be portable? Looked at assembly plugin documentation and not found any portability guide.

<fileSets>
    <fileSet>
        <directory>${basedir}/src/main/resources</directory>
        <outputDirectory>/</outputDirectory>
    </fileSet>
</fileSets>

Answer 1

The working solution is to specify the empty outputDirectory:

<fileSets>
    <fileSet>
        <directory>${basedir}/src/main/resources</directory>
        <outputDirectory></outputDirectory>
    </fileSet>
</fileSets>
