Unable to load the sbt project in IntelliJ with error: "Unable to determine previous version"

[Daniel-Khodabakhsh]

First time loading Alpakka with IntelliJ from the master branch synced just today and I get the error: Unable to determine previous version from method alpakkaProject in build.sbt.

Looks like alpakkaProject is used to load the projects and my error is happening when it's trying to load the mimaPreviousArtifacts setting for a project.

Is there a step I'm missing in my setup? I noticed the pipeline uses JDK 11 and i'm on JDK 17 but I have other scala 2.13.8 + sbt 1.5.8 projects that run on JDK 17 without issues so I feel like this isn't the problem.

Versions used

Akka version: 2.6.19 IntelliJ IDEA version: 2022.2.1

Expected Behavior

Should be able to open the project in IntelliJ and sbt should be able to load the projects.

Actual Behavior

When I open the project and let IntelliJ load the build.sbt file (or if I manually trigger loading build.sbt) I get the following error:

Ran the project load using the sbt shell setting in IntelliJ which results in the same error:

Reproducible Test Case

1. Install Eclipse Adoptium JDK 17
2. git clone the Alpakka project.
3. Try to open Alpakka with IntelliJ

[ennru]

Can you try to run sbt Test/compile from the shell before importing, please?

[Daniel-Khodabakhsh]

Sure thing @ennru !

Note: I'm using IntelliJ's sbt launcher plugin instead of a separate sbt installation. (this works fine for projects such as Slick).

When I try to open the sbt shell it gives me the following error:

[ennru]

Did you do a shallow clone/git fetch of the repo? The build needs to find the previous version tag in the git history.

[Daniel-Khodabakhsh]

No @ennru, I did a regular git clone, as in git clone https://github.com/akka/alpakka.git.

Just did a git pull and tested again but no luck.

Based on what you're saying, I checked if git is in my PATH and it wasn't. Adding it solved the issue.

Would it be possible to update the documentation (either README.md or CONTRIBUTING.md) to include this needed step? Or alternatively use a different plugin which includes its own git executable?

[ennru]

Thanks for trying again and identifying the reason. You're right, the sbt MiMa plugin uses git from the path. Would you be in a position to suggest an update to the contributor instructions?

[Daniel-Khodabakhsh]

Sure thing @ennru! I've just created a pull request now: https://github.com/akka/alpakka/pull/2938 Do I keep this issue open until the PR is merged? Otherwise feel free to close this issue.
