How to get available repository/commit parameters to pass to jenkins?

Recently we received an anonymous feedback via the feedback button (which will be discontinued and soon) in SCM-Manager. With the next release the button will be replaced with a footer link for feature requests.

Question was:

How to get available repository/commit parameters to pass to jenkins? Sth like repository.id or commit.author.mail in doc, how to retrieve this attribute list that I can use?

Answer:
for Jenkins build parameters you can use the repository and the commit. Please also note the inline comments

Here you can find all fields for:

Repository: scm-el-plugin/ImmutableEncodedRepository.java at develop · scm-manager/scm-el-plugin · GitHub

Commit: scm-el-plugin/ImmutableEncodedChangeset.java at develop · scm-manager/scm-el-plugin · GitHub
