Class ClasspathHellDuplicatesCheckRule

  • All Implemented Interfaces:
    org.junit.rules.TestRule
    public class ClasspathHellDuplicatesCheckRule
extends Object
implements org.junit.rules.TestRule
    JUnit Rule to run detect duplicate entries on the classpath. Usage: 
    public static @ClassRule ClasspathHellDuplicatesCheckRule
     dupes = new ClasspathHellDuplicatesCheckRule();

    NB that the basepom/duplicate-finder-maven-plugin already runs as part of odlparent. It has a similar purpose, but covers build time instead of runtime testing. This JUnit Rule class is thus recommended to be used in particular in tests which previously ran into JAR Hell issues, and for which non-regression with a clear failure message in case of future similar problems is important. (This provides more details at runtime than duplicate-finder-maven-plugin does at build time.)
