----------------------------------

             Summary: Cannot use Maven to install a project on a NetApp volume
                 Key: MNG-7498
                 URL: https://issues.apache.org/jira/browse/MNG-7498
             Project: Maven
          Issue Type: Bug
          Components: Deployment
    Affects Versions: 3.8.6
         Environment: RHEL 7 with a NetApp file server.
            Reporter: Michael Bauer


By default, every directory in a volume that is exported from a Network Appliance contains a directory named '.snapshot'.  That directory is created and maintained by the NetApp.  It is read-only; it cannot be deleted or altered.

 

Maven appears to refuse to install into a directory that is not cleaned out, and because of the nature of the subdirectory .snapshot it cannot delete that subdirectory.  Ergo, I get errors like:

 

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-clean-plugin:3.1.0:clean (clean-target-dir) on project apache-maven: Failed to clean project: Failed to delete /usr/sup/apache-maven-3.8.6/.snapshot -> [Help 1]

 

/usr/sup is on a NetApp volume.  I did not ask for 'clean' on this install:

 

% mvn -DdistributionTargetDir='/usr/sup/apache-maven-3.8.6' install

 

I am a sysadmin, not a developer.  My ideal is repeatable builds, so I would prefer to have a way to do this that uses released software.  End goal: a professor wants Hadoop, and Hadoop wants to be installed with a newer version of Maven than RHEL 7 provides.  If I can't install Maven with Maven, I don't expect that installing Hadoop with Maven will work either.

 

Is there a way to tell Maven to ignore the .snapshot subdirectory in an otherwise empty target directory?
