See the example in https://git.eclipse.org/r/#/c/154952/

Patchset 6 failed with

Failed to execute goal org.eclipse.tycho.extras:tycho-eclipserun-plugin:1.7.0:eclipse-run
(api-analysis) on project org.eclipse.ui.forms: Error while
executing platform: Error while executing platform (return"

at the end of the log.

The cause could be found somewhere up the log

Could this be improved so this message is visible at the end of the build log?

For the moment, https://www.eclipse.org/tycho/sitedocs/tycho-extras/tycho-eclipserun-plugin/eclipse-run-mojo.html doesn't capture system.err to wrap it into the MojoFailureException that is used to generate the final log.
This requires an enhancement in Tycho to enable that. Please open a ticket, or even directly a patch to Tycho.
