How to add a build timestamp to the title of an application built with Tycho - maven

Question

Is there a way to have the product name, which is shown in the title of the started application, set by the Tycho build?
Currently, the title of my application is the static product name set in the product configuration file. However I want to add a build number or timestamp to that title to better distinguish the different builds of the application.
So instead of My Application, I would like to have My Application (<buildNr>-<date>) with the build number and date expanded.
If this is not possible with Tycho, any other solution is welcome.

Answer 1

I am not sure if it is an ideal solution but I did the following:
To properly set the application title the product name has to be set, as it is also used in the About <productName>-menu item, furthermore it is returned when Platform.getProduct().getName() is called. (Which is used sometimes in my legacy product.)
To set the product name while building I do the following:
read the product name from the plugin.properties file
modify the plugin.properties with Tycho (Maven)
1. Read the product name from the plugin.properties file
To make it easier to modify the product name via Maven, that String is externalized to plugin.properties.
In the plugin configuration file and in the plugin.xml, the product name should be set to %product.name.
Then in the plugin.properties add the following line:
product.name=#productName#
If you start your product now, the application title should be #productName#.
2. Modify the plugin.properties with Tycho (Maven)
To change #productName# to the desired text the Maven filtering is used. Eclipse can not start the product anymore if the standard filter delimiters (${productName}) are used, therefore I use the Ant like delimiters. This snippet needs to be added to the pom:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>2.4.3</version>
<configuration>
<encoding>UTF-8</encoding>
<delimiters>
<delimiter>${*}</delimiter><!-- to keep the default behavior -->
<delimiter>#</delimiter><!-- to add Ant-like tokens style, this is needed as RCP has problems with the accolades -->
</delimiters>
</configuration>
</plugin>
I found this solution here on SO.
To replace #productName# with the actual value the Maven property <productName> has to be defined in the pom:
<properties>
<productName>MyApp_${maven.build.timestamp}</productName>
</properties>
<productName> can contain any value e.g. ${buildNumber} from the Build Number Maven Plugin.
Now the the only missing part is the following snippet which activates the filtering:
<resources>
<resource>
<directory>./</directory>
<includes>
<include>plugin.properties</include>
</includes>
<filtering>true</filtering>
</resource>
</resources>
