Change version of product - tycho

Question

I have a very basic project setup without sub-modules or anything. Just a pom.xml with nothing fancy:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>org.acme.product</groupId>
<artifactId>org.acme.product</artifactId>
<version>0.0.9</version>
<packaging>eclipse-repository</packaging>
<build>
<plugins>
<plugin>
<groupId>org.eclipse.tycho</groupId>
<artifactId>tycho-maven-plugin</artifactId>
<version>0.26.0</version>
<extensions>true</extensions>
</plugin>
<plugin>
<groupId>org.eclipse.tycho</groupId>
<artifactId>target-platform-configuration</artifactId>
<version>0.26.0</version>
<configuration>
<resolver>p2</resolver>
<target>
<artifact>
<groupId>org.acme.product</groupId>
<artifactId>org.acme.product</artifactId>
<version>${project.version}</version>
<classifier>platform</classifier>
</artifact>
</target>
<ignoreTychoRepositories>true</ignoreTychoRepositories>
<environments>
<environment>
<os>win32</os>
<ws>win32</ws>
<arch>x86</arch>
</environment>
</environments>
</configuration>
</plugin>
</plugins>
</build>
</project>
Of course there is a target platform named platform.target with the feature org.eclipse.equinox.executable.feature.group. Finally there is a (empty) product with the same ID and version.
Now I want to use Tycho to update this version. It's only two files, I know. Still.
mvn org.eclipse.tycho:tycho-versions-plugin:set-version -DnewVersion=1.0.0
The pom.xml will get updated, but the product not. The same thing works with plug-ins and features, I can't figure out why it won't work with products, too.
Can somebody help to change the product's version?

Answer 1

Check if your pom.xml version and product version are the same.
The versions-plugin will only update the versions in product files if the old version matches the version in the eclipse-repository POM.
Product files whose versions are (intentionally) different from the POM version are not updated. This is the same as with modules: modules which don't have the same version as the root POM are not updated.
