Koans archetype not working with empty Maven repository

[DavidWhitlock]

A student just emailed me and said that he got the following error while working with the koans:

$ mvn archetype:generate \
-DarchetypeCatalog=https://dl.bintray.com/davidwhitlock/maven/ \
-DarchetypeGroupId=edu.pdx.cs410J \
-DarchetypeArtifactId=java-koans-archetype \
-DarchetypeVersion=Summer2016 \
-DgroupId=edu.pdx.cs410J.rjr4 \
-DartifactId=koans \
-Dversion=1.0-SNAPSHOT

Geez. I've got a reference to an artifact from Summer2014. I need to fix that.

This probably worked in my environment because I've got the Summer2014 artifact in my local Maven cache. A new student wouldn't have that old jar and it's not available on bintray to download.

Tried changing Summer2014 to Summer2016 on line 55 in pom.xml. Recevied the following error.

[DavidWhitlock]

Oh, wow. It looks like I never updated the Koans archetype with all of the latest changes. I'm kind of surprised that the integration tests passed.

[DavidWhitlock]

Changes to address this issue have been merged to the master branch and have been deployed to the Maven repository.

@RJ-Russell and @kiarasht, will you guys try creating a Koans project from the latest archetype and let me know how it goes?

[RJ-Russell]

After removing the original koans project and going through all the steps again from scratch, I still received same errors.

[ERROR] Failed to execute goal on project koans: Could not resolve dependencies for project edu.pdx.cs410J.rjr4:koans:jar:1.0-SNAPSHOT: Could not find artifact com.sandwich:koans-lib:jar:Summer2014 in CS410J (https://dl.bintray.com/davidwhitlock/maven) -> [Help 1]

And then after changing 'Summer2014' in pom.xml to 'Summer2016':

[ERROR] Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.2.1:java (default-cli) on project koans: An exception occured while executing the Java class. null: InvocationTargetException: Can't find resource for bundle java.util.PropertyResourceBundle, key interactive -> [Help 1]```

[Kiarasht]

That's weird. It worked for me before / after your merge.

You need to open the file C:\Users\Restart\IntellijProjects\koans\src\beginner\AboutKoans.java. There should be a method starting with @Koan called findAboutKoansFile, look within it for your first lesson. Once you have solved that, save the file and check back for your next lesson.

Ponder what's going wrong in the: AboutKoans class's findAboutKoansFile method.

Line 11 may offer a clue as to how you may progress, now make haste!

Edit & save a koan to reload or enter 'Q' to exit

[RJ-Russell]

I just redid it again...and still not working. I tried this on two different systems again. Same errors.

[RJ-Russell]

So....after removing maven from my PATH, then then removing the .m2 maven directory from my homedir. Then removing everything koans related...and finally doing a reboot and re-symlinking the mvn exectuable back into my PATH.....and redoing all the koans archetype stuff....it works.

I'm thinking something was cached in there that was causing it to not read the new files?

Anyway..it seems to be working now. Thank you for your time and patience

[DavidWhitlock]

Thank you, @RJ-Russell. I really appreciate you getting a head start on the classwork and finding this critical defect. I'm glad you got it working.
