<file> s not on its project's build path

I get the following log output:

tomcat/work/Catalina/localhost/_/org/apache/jsp/tag/web/shared/googleTagManager/dataLayerInc [in platform] is not on its project's build path
Java Model Exception: Java Model Status [tomcat/work/Catalina/localhost/_/org/apache/jsp/tag/web/shared/googleTagManager/dataLayerInc [in platform] is not on its project's build path]
	at org.eclipse.jdt.internal.core.JavaElement.newJavaModelException(JavaElement.java:580)
	at org.eclipse.jdt.internal.core.Openable.generateInfos(Openable.java:253)
	at org.eclipse.jdt.internal.core.Openable.openAncestors(Openable.java:527)
	at org.eclipse.jdt.internal.core.Openable.generateInfos(Openable.java:247)

The tomcat folder should not be on the build path, so this error is not really an error!
Unfortunately the SAP Hybris Eclipse projects are pretty messed up (not fixable by me).

Environment

• Operating System: macOS 10.12.6 (16G1314)
• JDK version: java version "1.8.0_144"
• Visual Studio Code version: 1.24.1 (1.24.1)
• Java extension version: 0.27.0

Steps To Reproduce

Build the SAP Hybris platform project.

Current Result

Exception is thrown.

Expected Result

Don't throw an exception in that case, because it is not an exception, just ignore the file.

Riprodurre il problema compilando il progetto della piattaforma SAP Hybris nell’estensione Java. Tracciare la gestione della Java Model Exception per i percorsi tomcat/work che si trovano al di fuori del percorso di build del progetto, quindi verificare che la build venga completata senza segnalare questo percorso come un’eccezione.
