Missing Maven Plugin Jetty

Question

I am having trouble folowing this http://hrycan.com/2012/03/28/primefaces-lazy-loading-datatable-for-jsf2/

It says I should just run

mvn jetty:run

but I keep on encountering this error.

org.apache.maven.plugin.prefix.NoPluginFoundForPrefixException: No plugin found
for prefix 'jetty' in the current project and in the plugin groups [org.apache.m
aven.plugins, org.codehaus.mojo] available from the repositories [local (C:\MyRepo), central (http://repo1.maven.org/maven2)]
        at org.apache.maven.plugin.prefix.internal.DefaultPluginPrefixResolver.r

I used Maven 3 here.

Any thoughts?

ADD:

From the link, it has this already in the pom.xml

<plugin>
    <groupId>org.mortbay.jetty</groupId>
    <artifactId>jetty-maven-plugin</artifactId>
    <version>7.5.1.v20110908</version>
    <dependencies>
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>${mysql.version}</version>
        </dependency>
    </dependencies>
</plugin>

Answer 1

Did you add the plugin to the pom.xml? A quick google search found this:

<project>
  ...
  <build>
    ...
    <plugins>
      <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>jetty-maven-plugin</artifactId>
      </plugin>
    </plugins>
  </build>
</project>

Found here: http://mojo.codehaus.org/jetty-maven-plugin/usage.html

Answer 2

The instructions at (http://www.eclipse.org/jetty/documentation/current/jetty-maven-plugin.html) say to put the version as ${project.version} which is wrong! Also, the older documentation has the groupId set to org.codehaus.mojo it should be set to org.eclipse.jetty.

I added a real version from the jetty repo (http://repo.maven.apache.org/maven2/org/eclipse/jetty/jetty-maven-plugin/) and changed the groupId.

<plugin>
  <groupId>org.eclipse.jetty</groupId>
  <artifactId>jetty-maven-plugin</artifactId>
  <version>9.0.5.v20130815</version>
</plugin>

Answer 3

Check if it works after adding the following in settings.xml as documented.

<pluginGroups>
    <pluginGroup>org.mortbay.jetty</pluginGroup>
</pluginGroups>

Also note that there are two different versions of the plugin - the older maven-jetty-plugin and the newer jetty-maven-plugin.

Make sure you are executing command 'mvn jetty:run', from inside your project directory. If you will listed the current directory you should see the pom.xml.

If you are in not in your project and running 'mvn jetty:run', will get Error "Missing Maven Plugin Jetty"

        <plugin>
            <groupId>org.mortbay.jetty</groupId>
            <artifactId>jetty-maven-plugin</artifactId>
            <version>8.1.12.v20130726</version>
            <configuration>
                <stopKey>todostop</stopKey>
                <stopPort>9999</stopPort>
            </configuration>
        </plugin>

Hope it will help

I had this problem too. I started jetty:run from within Eclipse using a "Maven Build" run configuration.

The problem was, within my Maven Build run configuration, the "base directory" (i.e. the working directory used by the mvn executable) was set incorrectly. Setting the base directory to the directory containing the pom.xml fixed the problem.

Answer 6

Most probably your version is wrong. Try

    <plugins>
        <plugin>
          <groupId>org.eclipse.jetty</groupId>
          <artifactId>jetty-maven-plugin</artifactId>
          <version>9.2.6.v20141205</version>
        </plugin>
    </plugins>

Answer 7

Beside the plugin part you should be in the pom.xml directory to make starting the jetty command.
