Here are 3 sentences summarizing the key points from the document: The document provides 7 tips for developing OSGi applications with Eclipse and Tycho including adopting a modular structure with bundles and features, generating version qualifiers with Git, using target platforms for dependency management, leveraging Maven repositories for modular builds and aggregation, avoiding overuse of the Maven parent POM, and setting up build chains that include unit testing. It encourages learning about Maven concepts and adopting best practices for project structure when building OSGi applications.

5. Generate .qualifier with Git

<artifactId>tycho-packaging-plugin</artifactId>
<dependencies>
<dependency>
<groupId>org.eclipse.tycho.extras</groupId>
<artifactId>tycho-buildtimestamp-jgit</artifactId>
<version>${tycho-extras.version}</version>
</dependency>
</dependencies>
<configuration>
<timestampProvider>jgit</timestampProvider>
<format>'v'yyyyMMdd-HHmm</format>
<additionalFileSets>…</additionalFileSets>
</configuration>
</plugin>

6. Use target platforms for
dependency management.

7. Use Maven repositories for
modular builds and aggregation.

8. Don’t put everything into the
Maven parent.

9. Setup Build Chains
