Starting Eclipse Commandline With Equinox Launcher/Headless JUnit Testing

If you're looking to run JUnit tests headlessly, here's a bash script that does that as part of a headless PDE build. Relevant part starts at line 191:

# different ways to get the launcher and Main class
if [[ -f eclipse/startup.jar ]]; then
  cpAndMain="eclipse/startup.jar org.eclipse.core.launcher.Main"; # up to M4_33
elif [[ -f eclipse/plugins/org.eclipse.equinox.launcher.jar ]]; then
  cpAndMain="eclipse/plugins/org.eclipse.equinox.launcher.jar org.eclipse.equinox.launcher.Main"; # M5_33
else
  cpAndMain=`find eclipse/ -name "org.eclipse.equinox.launcher_*.jar" | sort | head -1`" org.eclipse.equinox.launcher.Main";
fi

# run tests
echo "[runtests] [`date +%H\:%M\:%S`] Launching Eclipse (installmode = $installmode with -enableassertions turned on) ..."
execCmd "$JAVA_HOME/bin/java $Xflags -enableassertions -cp $cpAndMain -ws $ws -os $os -arch $arch \
