org.eclipse.tycho:tycho-compiler-plugin:4.0.8:validate-classpath fails wth ds 1.4

[mikerumpf]

When builing with the following tycho-ds-plugin settings and having updated dsVersion from 1.3 to 1.4

            <plugin>
                <groupId>org.eclipse.tycho</groupId>
                <artifactId>tycho-ds-plugin</artifactId>
                <version>${tycho.version}</version>
                <configuration>
                    <classpath>true</classpath>
                    <dsVersion>1.4</dsVersion>
                    <enabled>true</enabled>
                    <path>OSGI-INF</path>
                    <skip>${tycho-ds.skip}</skip>
                </configuration>
            </plugin>

bundle compilation fails on some bundles with the following error:

[ERROR] Failed to execute goal org.eclipse.tycho:tycho-compiler-plugin:4.0.8:validate-classpath (default-validate-classpath) on project my.test.application2: Execution default-validate-classpath of goal org.eclipse.tycho:tycho-compiler-plugin:4.0.8:validate-classpath failed: org.osgi.framework.BundleException: Bundle my.test.application2 cannot be resolved:my.test.application2 [34]

A quick fix would be to add org.apache.felix.scr to the bundle dependencies. But am I missing something? My guess is that capabilities shouldn't be validated at compile level...

Thanks in advance for any help.

This is likely due to

• [DS] Validation of transitive generated 'osgi.extender=osgi.component' requirement fails #3824

can you check if adding

<plugin>
	<groupId>org.eclipse.tycho</groupId>
	<artifactId>target-platform-configuration</artifactId>
	<version>${tycho.version}</version>
	<configuration>
		...
		<dependency-resolution>
			<extraRequirements>
				<requirement>
					<type>eclipse-plugin</type>
					<id>org.apache.felix.scr</id>
					<versionRange>0.0.0</versionRange>
				</requirement>
			</extraRequirements>
		</dependency-resolution>
	</configuration>
</plugin>

works as a workaround?

[mikerumpf]

Yes, the workaround works. Thanks a lot! :-)

This issue is a duplicate. I will close it
