------------------------------------
Summary: Grapes fails to download artifact if POM exists in m2
local, but jar does not
Key: GROOVY-8655
URL: https://issues.apache.org/jira/browse/GROOVY-8655
Project: Groovy
Issue Type: Bug
Components: Grape
Affects Versions: 2.5.0
Environment: Groovy Version: 2.5.0 JVM: 1.8.0_172 Vendor: Azul
Systems, Inc. OS: Mac OS X
Reporter: Mike Robinet
Attachments: grapeError.log
*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.
