i unable find jars/classes getting conflict.

and want know best way overcome such conflict.

thanks!

the conflicts coming using version of jquery plugin doesn't work version of s2 you're using. 3.5.1 of s2 jquery plugin requires s2 2.3.8, its pom shows (in struts2-jquery, plugin's parent project).

you cannot arbitrarily mix-and-match versions of libraries; must respect dependencies unless they're compatible. it's why have tools maven.

one way highlight possible conflicts use mvn dependency:tree , see there multiple versions of same library.
