maven release版本重复上传error

• user credentials are wrong
• url to server is wrong
• user does not have access to the deployment repository
• user does not have access to the specific repository target
• artifact is already deployed with that version if it is a release (not -SNAPSHOT version)
• the repository is not suitable for deployment of the respective artifact (e.g. release repo for snapshot version, proxy repo or group instead of a hosted repository)

在项目中，版本名称后缀为：-RELEASE。如上所述，此后缀版本，不允许覆盖。如果一定要提交，要么删除私服上已经存在的版本，要么升级版本重新发布。
