OK, I'm trying to get my first mojo working.
I created a project with the maven-plugin archetype and used the default
mojo that is there, but I cannot seem to get it to run.
The first time I tried to run it maven complained it could not find the
plugin. So then I ran a maven install, but it still could not find it
because it would only look in Nexus for it - why doesn't it just look in the
local repository? Then I ran a maven deploy, so the plugin project artifacts
are definitely in Nexus now, but maven is still complaining it cannot find
the POM for the plugin.
I suspect the problem is my plugin is version 0.0.1-SNAPSHOT but the files
in Nexus are like
nexus/content/repositories/snapshots/com/kodak/jni4net/jni4net-maven-plugin/0.0.1-SNAPSHOT/jni4net-maven-plugin-0.0.1-20110829.135006-1.pom
and the POM I am trying to run the plugin from looks like
<plugin>
<groupId>com.kodak.jni4net</groupId>
<artifactId>jni4net-maven-plugin</artifactId>
<version>0.0.1-SNAPSHOT</version>
<executions>
<execution>
<phase>validate</phase>
<goals>
<goal>proxygen</goal>
</goals>
</execution>
</executions>
</plugin>
Does anyone have any advice?
How are you calling your plugin? In a POM? Or on the command line? You
need to make sure Maven knows the group id for the plugin so just
invoking (e.g.) mvn jni4net:proxygen is not going to work. Well, not
without extra work anyway.
By the way, if I want to share this plugin with the open source community,
how would I go about learning how to do that? Is there some global
repository I can submit it to (because I do not want to have to publish a
repository from our corporate intranet on the internet)? jni4net comes from
SourceForge - perhaps that would be the best place to start?
A global repository? You may have heard of Central? :-)
