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:

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
