Today I tried to use lambda expression in my project. I configured my project to use Java 8 everywhere: Build path, Java Compiler, maven-compiler-plugin, but it shows errors when I do "Run / Maven Install".

This

definitely indicates that you're running with a version of javassist that cannot understand the InvokeDynamic tag in a class file's constant pool.
Accorinding to class ConstPool this tag should be supported since 3.17.
Perhaps mvn -X will reveal which version of javassist is actually used. Actually, if the error occurs during mvn install the version of javassist is not determined by build.dependencies but you'd have to tell the Maven plugin that uses javassist, to use a recent version of it. You should check which maven plugin corresponds to the Java package org.hibernate.ejb.packaging in your stack trace. Then add a corresponding dependency (javassist) to that maven plugin.
