Description

When calling scm:update in detached HEAD:

[INFO] Executing: /bin/sh -c cd '/path/to/project' && 'git' 'log' '-n1' '--date-order' 'master'
[INFO] Working directory: /path/to/project
[ERROR] Provider message:
[ERROR] The git-log command failed.
[ERROR] Command output:
[ERROR] fatal: ambiguous argument 'master': unknown revision or path not in the working tree.

When no ScmVersion is given, the plugin defaults to master (https://github.com/apache/maven-scm/blob/master/maven-scm-providers/maven-scm-providers-git/maven-scm-provider-gitexe/src/main/java/org/apache/maven/scm/provider/git/gitexe/command/update/GitUpdateCommand.java#L169), defaulting to HEAD would be better, no ?
