svn - リモートリポジトリへのリリース maven release:prepare エラー - pom.xml は作業フォルダーではありません

Question

こんにちは、単純な mvn リリースを実行しようとしています。簡単なMavenプロジェクトを作成しました。デフォルトの hello world クラスしかありません。mvn release:prepare -Dresume=false -Dusername=abc -Dpassword=xxx -DtagBase= https://subversion.assembla.com/svn/ems/tags/を実行しようとすると

次のエラーが表示されます
