How to exclude specific class from a Maven dependency ( Jar dependency) at runtime

Question

How to exclude specific class from a Maven dependency ( Jar dependency).

I have an issue with ObjectUtils.class from avro-tools.jar which is picked in run time that does not have method which is used from commons-lang3 jar. Which causing runtime NoSuchMethod error.

I wanted to know is there any way i can specify in my pom.xml to exclude this class org.apache.commons.lang3.ObjectUtils from avro-tools.jar (1.9.1) version and pick it from commons-lang3.jar (3.9 version)

Answer 1

try maven-shade-plugin,it will remove class from final jar generated by pom.xml

Note :- Removing particular class from jar is not possible.
