   Hi Shi Chen (@CsCherrYY), I'm an AI Support assistant here to help with your issue. While the team reviews your request, I wanted to provide some possible tips and documentation that might help you in the meantime.

   Suggestions to address “The type xxx cannot be resolved. It is indirectly referenced from required .class files”:

   • Ensure any missing libraries are on your classpath/module-path

     • For example, if you see this for javax.servlet.http.HttpServletResponse, add the servlet API jar or Maven/Gradle dependency (see issue #2123).
     • Similarly add any external .class files that define the missing types.

   • If you’re using --release 9 on JDK 11, know that Java SE 9 doesn’t include certain APIs (e.g. servlet), so either:

     • Change --release to 11 or
     • Add the required modules/jars explicitly via --add-modules or classpath entries.

   • Upgrade to a version of the Java language server that includes the fix from eclipse.jdt.core PR 327:
     Bug 576735 - "Type cannot be resolved. It is indirectly referenced from required .class files" error message not helpful eclipse-jdt/eclipse.jdt.core#327

   High-confidence references:

   • Cannot find the class file for javax.servlet.http.HttpServletResponse (#2123)
     • Same error code (16777540) when a servlet API is missing; solution is to add the servlet API dependency.
       Cannot find the class file for javax.servlet.http.HttpServletResponse. redhat-developer/vscode-java#2123

   Other references with low confidence:

   Related JDT core JDK-11 + --release=9 breakage

   • Release option 9 breaks compilation on JDK 11; several projects report similar indirect reference errors.
   Issue: eclipse-jdt/eclipse.jdt.core#539

   The team will respond to your issue shortly. I hope these suggestions are helpful in the meantime. If this comment helped you, please give it a 👍. If the suggestion was not helpful or incorrect, please give it a 👎. Your feedback helps us improve!
