New merge behavior causes issues when sub-modules where added to the develop branch

[simontunnat]

The new merge behavior introduced with plugin version 1.18.0 causes issues in the following case:

1. A release or hotfix branch has been created
2. New sub-modules where added in the develop branch ("ui.config/local.author65" and "ui.config/local.publish65")
3. We try to finalize the release or hotfix

The issue here seems to be that the plugin has checked out branch "release/22.4.0" but does not correctly reload the project info.

The problem does not occur if we set the "noBackMerge" and "noBackMergeHotfix" parameters or if we downgrade to version 1.17.0.

I could try to create a minimal test case for this if you need this to reproduce the error.

[simontunnat]

I had a hard time creating a minimal integration test for this. :/
I will inspect further as this might have something to do with one of the other plugins we are using.

[aleksandr-m]

Not clear. How development branch changes are related to hotfix? How project reloading is related to merging?

[wumpz]

Same exceptions here after upgrading to version 1.18.

[beatngu13]

This might has to do with #324? At least "Error re-loading project info" indicates that.

Unfortunately, the stack trace stops there. Could add the full stack trace?

[aleksandr-m]

@wumpz Which exception? Can you be more specific. Steps to reproduce?

[wumpz]

Sorry. Typo. Same error for missing version information. I guess those versions ar defined in the roots dependency management section

I also built a minimal example repository for the issue:
https://github.com/simontunnat/maven-gitflow-ci-new-merge-behaviour-issue-example
(Checkout the develop branch and execute the command mvn clean gitflow:release-finish -B -DcommitDevelopmentVersionAtStart -DuseSnapshotInRelease -DpushRemote=false)

[simontunnat]

I think the issue is that Maven for some reason tries to evaluate the sub-module "module-b" when the release branch is checked out, even though the sub-module only exists in the "develop" branch.

This loop here gets all projects and these already include "module-b". :(

[simontunnat]

It seems by example project also fails with the release-finish goal with version 1.17.0.
My initial problem did only occur with version 1.18.0.

[aleksandr-m]

@simontunnat Thanks for the repro.

It is not about merge behavior. It is about checking for SNAPSHOT dependencies with the new project reloading. We need to obtain projects the same way as the current project, and then there is no need to reload project in the loop.

[aleksandr-m]

1.19.0 is released.
