How to create update site without rebuilding all features? [message #1852624]

Hi

I have an application with a lot of features. I can add all these features to an update site project and build it. The problem is that all of the features has a new build date and all of them will be updated in the application.

Is it possible to create an update site without rebuilding all features? So only changed features are updated. For example https://download.eclipse.org/releases/2021-03/ contains bundles with different build dates. How to achieve it?

Mostly these days folks build with Maven/Tycho and build an update site with a category.xml. Tycho has things like this

        <plugin>
          <groupId>org.eclipse.tycho</groupId>
          <artifactId>tycho-packaging-plugin</artifactId>
          <version>${tycho-version}</version>
          <configuration>
            <format>'v'yyyyMMdd-HHmm</format>
            <sourceReferences>
              <generate>true</generate>
            </sourceReferences>
            <timestampProvider>jgit</timestampProvider>
            <jgit.ignore>pom.xml</jgit.ignore>
            <jgit.dirtyWorkingTree>warning</jgit.dirtyWorkingTree>
            <additionalFileSets>
              <fileSet>
                <directory>${project.build.outputDirectory}</directory>
                <includes>
                  <include>about.mappings</include>
                </includes>
              </fileSet>
            </additionalFileSets>
          </configuration>

which uses https://www.eclipse.org/tycho/sitedocs/tycho-packaging-plugin/build-qualifier-aggregator-mojo.html to compute the timestamp based on git commits in the tree...
