> *Steps to reproduce:*
>  * These instructions use slf4j-api as an example, but it is reproducible with any artifact.
>  * Remove local Grapes cache: {{rm -rf ~/.groovy/Grapes}}
>  * Remove org.slf4j:slf4j-api artifacts from Maven local cache: {{rm -rf ~/.m2/repository/org/slf4j/slf4j-api}}
>  * Remove any custom Ivy or Grapes config
>  * Download POM only for slf4j-api: {{mvn dependency:get -Dartifact=org.slf4j:slf4j-api:1.7.25:pom -Dtransitive=false}}
>  * Attempt to install slf4j-api using Grapes: {{grape -V install org.slf4j slf4j-api 1.7.25}}
> *Expected behavior:*
>  * slf4j-api 1.7.25 jar is downloaded from jcenter
> *Actual Behavior:*
>  * Fails to retrieve jar with NOT FOUND error (verbose log attached):
>  
> {noformat}
> :: problems summary ::
> :::: WARNINGS
>  [NOT FOUND  ] org.slf4j#slf4j-api;1.7.25!slf4j-api.jar (0ms)
>  ==== localm2: tried
>    file:/Users/Mike/.m2/repository/org/slf4j/slf4j-api/1.7.25/slf4j-api-1.7.25.jar
> {noformat}
> *Workaround:*
>  * Delete slf4j-api/1.7.25 folder in Maven local and Grapes cache folder and reinstall.
> *Additional notes:*
> It is fairly common to only have the POM file for artifacts in your Maven local. I use the [gradle-versions-plugin|https://github.com/ben-manes/gradle-versions-plugin] frequently which is just one example of a tool that downloads only POM files for artifacts.
