I've just started helping my professor out for his research project and I'm trying to get it set up on my local windows computer. I'm stuck with this error:

Failed to execute goal on project tornado: Could not resolve dependencies for project tornado:tornado:jar:0.0.1-SNAPSHOT: Failure to find com.disco:disco:jar:10.2.0 in http://clojars.org/repo was cached in the local repository, resolution will not be reattempted until the update interval of clojars.org has elapsed or updates are forced

Notes:

  • It's a maven project being run on eclipse.

  • I've tried multiple ways of adding the disco-2.0.jar file to the build path but I'm not sure if that's what I'm meant to be doing or if it's even the right file, although I haven't found any other disco file within the project directories.

  • I've tried mvn clean install -U to see if it may just have been a problem with resetting the maven project.

Well the log reads is clear and you could verify it as well:

Failure to find com.disco:disco:jar:10.2.0 in http://clojars.org/repo

If you navigate to the https://clojars.org/repo/com/ there is no disco.jar available there. Hence the failure.

Probably this could be some local jar that might need to be build either locally or required by its owner to be pushed(mvn deploy) to clojars in another case.

Also mvn clean install -U help you fetch the latest of SNAPSHOT, in your case this would fetch the latest tornado:tornado:jar:0.0.1-SNAPSHOT but that fails further sicne it specifies the com.disco:disco:jar:10.2.0 as dependency which is not found anywhere for your build to proceed.

You need to make the disco-2.0.jar available from a Maven repository. If you have a Nexus or Artifactory, upload it there. Alternatively, you can install it into the local repository of your computer using the install:install-file goal.

Furthermore, it is possible to define local directories as additional Maven repositories, see https://stackoverflow.com/a/28762617/927493.
