Re: [m2e-users] Error maven-jar-plugin:2.3.1:jar (default-jar)

This is not m2e-specific issue, but an issue in one of components used
by maven core plugins, maven-jar-plugin in your case.

If the build works when invoked from command line but does not work from
m2e, the easiest workaround is to configure external maven installation
in Preferences->Maven->Installation.

More permanent solution is to configure specific version of
maven-jar-plugin in pom.xml. This will make your project work more
reliably across different versions of maven.

Hi,

working on a macosx computer, I am repeatedly getting the following
error while running maven within eclipse:

Failed to read filesystem attributes for:
/Users/ceugster/Projekte/Enterprise OSGi in
Action/PDE-Workspace/com.fancyfoods/com.fancyfoods.api/pom.xml: Failed
to retrieve numeric file attributes using: '/bin/sh -c ls -1nlad
'/Users/ceugster/Projekte/Enterprise OSGi in
Action/PDE-Workspace/com.fancyfoods/com.fancyfoods.api/pom.xml'

see below.

Running mvn from the console executes with no errors. Running in Windows
XP executes with no errors too. I am new to maven and m2e so I don't
know how to solve this problem.

Thanks
