Generate and display Maven Build timestamp in WAR

On all the pages of my webapp I want to see when the WAR was built (i.e. a build timestamp). Here is how I did it:

Add this to the pom.xml of your webapp module:



Create a file src/main/resources/build.properties in  in your webapp module with the following content:

# Build Time Information

The Maven build will replace the Maven property and the resulting file WEB-INF/classes/build.properties will look like this:

# Build Time Information

Now we just need a Spring PropertiesFactoryBean definition to make properties available at runtime:

<bean id="appProperties" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
  <property name="locations">

I used a simple Spring bean to make the timestamp easily available in Spring Web Flow / Spring Faces EL expressions:

public class ViewUtil {

  private Properties appProperties;

   * @param appProperties Global Application properties
  public void setAppProperties(Properties appProperties) {
    this.appProperties = appProperties;

   * @return The Build Timestamp as generated by Maven
  public String getBuildTimestamp() {
    return appProperties.getProperty("build.timestamp", "UNKNOWN");

The EL expression code in the JSF page is then something like this:

Build timestamp: #{viewUtil.buildTimestamp} 

And this is what the result looks like on the page:

If you want to be able to refer to properties directly by name in your Spring configuration you can define a Spring PropertyPlaceholderConfigurer:

<bean id="propertyConfigurer"
  <property name="properties" ref="appProperties" />

    Very well written Oliver. I’d like to familiarize myself with Maven. We use Ant and SVN. Can you suggest some good examples/starting point? So many examples are available but many expect a little background in Maven. I don’t have any prior experience with it.
