How do I use Jenkins Pipeline properties step?

Question

I am studying capabilities of Jenkins Pipeline:Multibranch. It is said that a recently introduced properties step might be useful there, but I can\'t catch how

Answer 1

Using properties with explicit method syntax will work, i.e.:
properties( [ ... ] ) rather than properties [ ... ]

Alternatively, it will work without if you specify the parameter name, e.g.:

properties properties: [ ... ]

For example defining three properties is as easy as :

properties([
  parameters([
    string(name: 'submodule', defaultValue: ''),
    string(name: 'submodule_branch', defaultValue: ''),
    string(name: 'commit_sha', defaultValue: ''),
  ])
])

/* Accessible then with : params.submodule, params.submodule_branch...  */
