install maven in CentOS




Display all the classes loaded by jvm in Eclipse

I have a maven project which referenced hibernate-jpa-2.0 then I upgraded to hibernate-jpa-2.1. I got rid of all the indirect references to jpa-2.0 in pom and added explicitly the reference to jpa-2.1 but somehow it still uses the old one. In order to find out which jar version it is using, I added ‘-verbose:class‘ vm parameter then found out it still uses jpa-2.0 on the classpath. Then I manually deleted jpa-2.0 from local maven repository and rebuilt the project. Then everything works fine.
