[deploy] Could not determine git HEAD null

[maxandersen]

if you do:

mkdir test
cd test
jreleaser init
git init 
jreleaser deploy

you get this error:

Could not determine git HEAD
null

which I assume is failing as no commits. since when done a git commit it tells me:

Could not determine remote
repository doesn't have a remote named 'origin'

[aalmiray]

That's correct. The deploy step requires running inside a git repository with at least 1 commit. and a default remote set. The current expectation is that the project is in a releasable state.

We may have to review/relax this constraint in the future.

[maxandersen]

To be clear I get it's expected to not work. It's just that the error message is not as informative "null" as it is in other cases.

[aalmiray]

Aha. Did you get a stacktrace when the error occurred? Look into out/jreleaser/trace.log

Right now deploy has no dependencies to other steps (Maven deployers do not require previous cheksums, signing, changelog for example). However, other deployers might require checksums for example. Still, even if there were step dependencies the deploy step could be invoked without requiring a git repository. This is the case for the assemble step.

There are 2 issues here:

• decouple deploy from git.
• better error message when no git remote, git commit, or git repository is required.

@maxandersen thoughts?

[maxandersen]

Sorry. Didnt see the message before now. All good fixes!
