How to run a snapshot plugin - maven

Question

When I attempt to run below maven plugin using this command :
com.wordpress.pomfromjarmavenplugin:generate:0.0.1-SNAPSHOT:generatepom
I get this error :
Downloading:
https://oss.sonatype.org/content/repositories/snapshots/com/wordpress/pomfromjarmavenplugin/generate/0.0.1-SNAPSHOT/generate-0.0.1-SNAPSHOT.pom

Problem seems to be that all of the pom files have timestamps associated with them :
https://oss.sonatype.org/content/repositories/snapshots/com/wordpress/pomfromjarmavenplugin/generate/0.0.1-SNAPSHOT/
How can I run this plugin ? Do I need to wait until the plugin is released or somehow instruct maven to run the latest version of the snapshot ?

Answer 1

Add these lines to your pom:
<pluginRepositories>
<pluginRepository>
<id>oss.sonatype</id>
<url>https://oss.sonatype.org/content/repositories/snapshots/</url>
</pluginRepository>
</pluginRepositories>
Then your command should work:
mvn com.wordpress.pomfromjarmavenplugin:generate:0.0.1-SNAPSHOT:generatepom
Or add these lines to your pom:
<build>
<plugins>
<plugin>
<groupId>com.wordpress.pomfromjarmavenplugin</groupId>
<artifactId>generate</artifactId>
<version>0.0.1-SNAPSHOT</version>
</plugin>
</plugins>
</build>
And then issue:
mvn generate:generatepom
