In Maven how do I copy files using the wagon plugin?

Summary: How do I copy some generated files into a webserver (eg IIS or Apache) directory using Maven?

Details: I have a working application that builds in Maven. I've managed to get it building using the webstart-maven-plugin which produces all the needed files (.jar and .jnlp) in a directory target/jnlp. It a开发者_JS百科lso creates a zip file with them all in at target/foo-1.0.zip.

At the moment the webstart plugin does not have a deploy goal - the request for it has ended up on the FAQ (question 3). It may be implemented in future, but the suggestion for the time being is to use wagon-maven-plugin.

I've never used Wagon. To start with I'd like to just copy the files to a local directory served up by a webserver. Later I'd like to copy them remotely, probably using ftp. Can someone give an example to what I need to add to the pom.xml to get the local copy working (and hopefully an ftp example too?). I can't find it in the documentation. From reading I think I might also need the Wagon Maven File Provider but as this seems to have almost no documentation I'm not sure.

Wagon providers are only there to provide additional network protocol supports (such as FTP).

If you want to copy file to a webserver (local or distant) you can use Maven upload plugin :

...
<plugin>
    <groupId>com.atlassian.maven.plugins</groupId>
    <artifactId>maven-upload-plugin</artifactId>
</plugin>
...

In parent pom :

            <plugin>
                <groupId>com.atlassian.maven.plugins</groupId>
                <artifactId>maven-upload-plugin</artifactId>
                <version>1.1</version>
                <configuration>
                    <resourceSrc>
                        ${project.build.directory}/${project.build.finalName}.${project.packaging}
                    </resourceSrc>
                    <resourceDest>${jboss.deployDir}</resourceDest>
                    <serverId>${jboss.host}</serverId>
                    <url>${jboss.deployUrl}</url>
                </configuration>
            </plugin>

And to configure parameters in a smart way, I use maven profiles (in parent pom) :

<profiles>
    <!-- local deployment -->
    <profile>
        <id>developpement</id>
        <properties>
            <jboss.host>localhost</jboss.host>
            <jboss.deployDir>appli/jboss-4.0.4.GA/server/default/deploy/</jboss.deployDir>
            <jboss.deployUrl>file://C:/</jboss.deployUrl>
        </properties>
    </profile>
    <!-- distant deployment -->
    <profile>
        <id>validation</id>
        <properties>
            <jboss.host>ENV_val</jboss.host>
            <jboss.deployDir>/home/envval/jboss/server/default/deploy/</jboss.deployDir>
            <jboss.deployUrl>scp://PROJECT_LAN_HOST</jboss.deployUrl>
        </properties>
    </profile>
</profiles>

I've created an "ant launcher", to use it by clicking under Eclipse ant view :

<target name="copy war to JBoss local" description="Copy war to local JBoss">
    <maven goal="upload:upload" options="-Pdeveloppement" />
</target>

But you can simply run it on a command line :

mvn upload:upload -Pdeveloppement

EDIT : By the way, for distant deployment, you may need a login password for scp to work. You have to add them to you Maven settings.xml file :

<settings>
  ...
  <servers>
    <server>
      <id>ENV_val</id>
      <username>login</username>
      <password>password</password>
    </server>
  </servers>
  ...
</settings>

EDIT: You'll need to add the Atlassian repository:

    <pluginRepositories>
    <pluginRepository>
        <id>Atlassian</id>
        <url>https://maven.atlassian.com/repository/public</url>
        <releases>
            <enabled>true</enabled>
        </releases>
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
    </pluginRepository>
</pluginRepositories>   

EDIT: depending upong the remote protocol you'll have to add wagon extensions, see Uploading a directory using sftp with Maven

In the end I didn't use the Maven upload plugin - it seemed a bit limited and not part of the main maven distribution. I used the maven wagon plugin as suggested. Here is the simplest possible pom that I could make that worked. Hopefully others will find it useful, as I couldn't find anything similar easily.

  <plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>wagon-maven-plugin</artifactId>
    <version>1.0-beta-3</version>
    <configuration>
      <fromDir>${project.build.directory}/jnlp</fromDir>
      <includes>*</includes>
      <url>file://c:/inetpub/wwwroot</url>
      <toDir>jnlp</toDir>
    </configuration>
  </plugin>

For remote distributions, you just change the URL type, and possibly add wagon extensions as necessary.
