Mvn error updating group repository metadata
Default value is: Parameter used to control how many times a failed deployment will be retried before giving up and failing.Apache Maven 2.0 goes to great lengths to ensure that builds are portable.When this option is specified, the profile(s) specified in the option argument will be activated in addition to any profiles which are activated by their activation configuration or the section in the profile itself.
If a value outside the range 1-10 is specified it will be pulled to the nearest value within the range 1-10."1.4.0_08", "1.4.2_07", "1.4"): This profile will automatically be active for all builds unless another profile in the same POM is activated using one of the previously described methods.All profiles that are active by default are automatically deactivated when a profile in the POM is activated on the command line or through its activation config.As such, profiles can easily lead to differing build results from different members of your team.However, used properly, profiles can be used while still preserving project portability. This option takes an argument that is a comma-delimited list of profile-ids to use.
Depending on where you choose to configure your profile, you will have access to varying POM configuration options. Anything that seems to stand a high chance of changing the result of the build is restricted to the inline profiles in the POM.
