Description

The current CommandLineUtils.executeCommandLine() in plexus-utils uses the StreamPumper class to copy the output of the 'mvn deploy' call. Because this class is line based, it cannot distinguish between a standard newline and a '\r'. Because of this the upload progress doesn't overwrite itself as the download progress usually does, but writes each step on a new line (see MRELEASE-55).

I've created 2 patches, one for the release-plugin itself and one for plexus-utils. I'm submitting the plexus-utils patch here as well, because of the direct relation with this report.

To test, replace the plexus-utils-1.1.jar in <m2_home>/core with the newly built plexus-utils-1.2-SNAPSHOT.jar. After this, import the web project in ReleaseTestWEB.zip into CVS and update the scm url in the pom. Perform a release:prepare and release:perform and verify that the upload counter stays on the same line.
