I want to upload my custom maven plugin to nexus repository.

My problem is that when I upload my plugin to nexus via web IU like ordinary dependency, maven can’t find it:

Plugin com.huawei:maven-project-version-plugin:1.0 or one of its
dependencies could not be resolved: Failed to read artifact descriptor
for com.huawei:maven-project-version-plugin:jar:1.0: Failure to find
com.mycompany:maven-project-version-plugin:pom:1.0 in
http://localhost:8081/nexus/content/groups/public was cached in the
local repository, resolution will not be reattempted until the update
interval of nexus has elapsed or updates are forced -> [Help 1]

But when I am install my plugin to maven local repositiry (not nexus) via command line all is fine.

So, what is the difference between installing custom maven plugin and installing “non plugin” artefacts? Are there any tricks?

My settings.xml: 

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" 
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">

    The problem was solved. Well, I don’t know how, but today all is work. I think the problem was in Nexus cache. I just deleted my hosted repository and created it again. Perhaps, there are less radical methods, but I don’t know them =) Delete artifact and then just “expire cache” not help in my case.

    Well, the answer of my question: There is no any different between installation plugin and non plugin artifact in Nexus, except one. If you select GAV Definition: GAV parameters, you must select “maven-plugin” in combobox “Packaging”.

    I think there is no need to write step by step instruction, it is very simple. Just select your hosted repository -> Artifact Upload tab and fill required fields.
