java.lang.ClassNotFoundException: org.aspectj.weaver.tools.PointcutParser
I use aspect in my project, and when I run it, this exception throws.
But When I remove my aspects, this issue disappears.
Can anyone help with this issue?
Thanks!!!
You need aspectjtools to your classpath

http://mvnrepository.com/artifact/org.aspectj/aspectjtools
It would be quite easy to add it as maven-dependency with compile-scope
