Lein new doesn't use installed snapshot templates (and fails to retrieve from Clojars if present)

[avescodes]

Hey there. Folks on this pedestal-dev thread (and myself) have run into a rather interesting set of circumstances that seem to force leiningen to not use a SNAPSHOT template dependency that exists in the local maven repository and fail to fetch that dependency from Clojars if it was installed via lein sub install.

Steps to reproduce:

• Remove any existing pedestal templates rm -rf ~/.m2/repository/pedestal-*

• lein new pedestal-service delete-me

  • This should retrieve the template from Clojars

• Remove pedestal templates again rm -rf ~/.m2/repository/pedestal-*

• Clone pedestal and lein sub install from inside the repository

• lein new pedestal-service delete-me

  ▸ lein new pedestal-service delete-me                                                                                                             
  Failed to resolve version for pedestal-service:lein-template:jar:RELEASE
  This could be due to a typo in :dependencies or network issues.
  Could not find template pedestal-service on the classpath.

I had an issue with using a template that worked just fine in the previous leinigen version; after the above I removed the SNAPSHOT from the project.clj and the template works fine. I.e. I can confirm the reported behavior. I'll be happy to answer any questions about my setup if needed.

This is now supported in 2.3.4.

I encountered this issue on lein 2.7.1 and resolved it with @kasterma's workaround of removing SNAPSHOT from my template's project.clj. The template has never been pushed to Clojars. Is this expected behavior?

$ lein -version
Leiningen 2.7.1 on Java 1.8.0_25 Java HotSpot(TM) 64-Bit Server VM

Can you specify what command you used?

[daveliepmann]

lein install in the template directory, then lein new <template name> <project name> in another directory.

[technomancy]

That explains it; you need a --snapshot argument when running lein new ....

I just ran into the same problem. Seems to work if I remove -SHAPSHOT suffix from the version prior to "lein install".
