There are no available Samebug tips for this exception. Do you have an idea how to solve this issue? A short tip would help users who saw this issue last week.

  • As specified in the document [https://confluence.atlassian.com/display/STASH/Automatic+branch+merging], Automatic Branch Merging demands the use of semantic versioning in branch names. The suggestion is to reinforce this in the UI when this option is configured and a branch is being created (so maybe when creating a new branch, the user would be advised about the semantic versioning and/or Stash would even stop the customer from creating a branch that not attend to this rule). Currently if this option is on and the user tries a merge using branches that do not attend to the semantic versioning an error occurs, not being clear about why it failed.
