Eclipse giving error while building project - java.lang.IllegalArgumentException: Malformed \uxxxx encoding

Question

error message while building project

Getting below error in eclipse 2021-12 while building project

Errors occurred during the build.
    Errors running builder 'Java Builder' on project 'xxx'.
    Unable to make protected final java.lang.Class java.lang.ClassLoader.defineClass(java.lang.String,byte[],int,int) throws java.lang.ClassFormatError accessible: module java.base does not "opens java.lang" to unnamed module @536d97f8
    Errors running builder 'Maven Project Builder' on project 'xxx'.
    java.lang.IllegalArgumentException: Malformed \uxxxx encoding.

I am using JDK 1.8

I tried deleting project, restarting eclipse and also re-installing JDK.

I tried adding below VM arguments but not worked

EDIT:

I see lombok is causing this issue

-(Unable to make protected final java.lang.Class java.lang.ClassLoader.defineClass(java.lang.String,byte[],int,int) throws java.lang.ClassFormatError accessible: module java.base does not "opens java.lang" to unnamed module @536d97f8 Errors running builder 'Maven Project Builder' on project 'xxx'.)

After installing lombok to eclipse IDE the issue got resolved.

But still I am getting below error while building - java.lang.IllegalArgumentException: Malformed \uxxxx encoding.

I see answers for same error but its the issue with Ant and its giving error for maven. I don't see any path where "\" is used in project/POM. Ant: Malformed \uxxxx encoding in propertyfile task

EDIT 2:

java.lang.IllegalArgumentException: Malformed \uxxxx encoding.

Above issue resolved after following below solution (it has step to step guide to fix the error) Solution
