Re: [m2] Getting SNAPSHOT information into a webapp

Hi Mark, 

I'm having the same requirement. I'm wondering if you have found a solution
on how to access the snapshot timestamp value.

Thanks,

Here's the source for my homebrew plugin to add a version file to my 
artifacts.  It's just writing a date and hostname, but you can easily 
change it to include other information such as version.

package com.vms.maven;

import java.io.File;
import java.io.FileOutputStream;
import java.io.PrintStream;
import java.net.InetAddress;
import java.text.SimpleDateFormat;
import java.util.Date;

import org.apache.maven.plugin.AbstractMojo;
import org.apache.maven.plugin.MojoExecutionException;
import org.apache.maven.project.MavenProject;


/**
 * Goal which creates/updates a version file
 *
 * @goal versionPage
 * @phase generate-resources
 */
public class VersionMojo extends AbstractMojo {
   
    /**
     * @parameter default-value="version.html"
     */
    private String filename;

    /**
     * @parameter default-value="MM/dd/yyyy HH:mm:ss"
     */
    private String dateFormat;

    /**
     * @parameter expression="${project}"
     * @required @readonly
     */
    protected MavenProject project;
       
    public void execute() throws MojoExecutionException {
        String outputDirectory;
        if ("jar".equals(project.getPackaging())) {
            outputDirectory = project.getBuild().getDirectory() + 
"/classes";
        } else {
            outputDirectory = project.getBuild().getDirectory() + "/" + 
project.getBuild().getFinalName();
        }
        File directory = new File(outputDirectory);
        if (!directory.exists()) {
            directory.mkdirs();
        }
        String fullFilename = outputDirectory + "/" + filename;
        File versionFile = new File(fullFilename);
        if (versionFile.exists()) {
            versionFile.delete();
        }
        SimpleDateFormat formatter = new SimpleDateFormat(dateFormat);
        try {
            String versionString = "built " + formatter.format(new 
Date()) + " on " + InetAddress.getLocalHost().getHostName();
            FileOutputStream output = new FileOutputStream(fullFilename);
            new PrintStream(output).println(versionString);
            output.close();
            getLog().info("Wrote version \"" + versionString + "\" to 
file " + fullFilename);
        } catch (Exception e) {
            throw new MojoExecutionException("FAILURE", e);
        }
    }
}
