the build automation tool. All nice & cool except that this project, checked out of SVN as is, is broken... meaning it fails to build, with several duplicate class errors: [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.1:compile (default-compile) on project myproj: Compilation failure: Compilation failure: [ERROR] \Users\Daniel\workspace\myproj\target\generated-sources\cxf\org\package1\services\ClassA.java:[36,7] duplicate class: org.package1.services.ClassA Now, it's true that ClassA exists in the build environment 3 times: c:/Users/Daniel/workspace/myproj/src/main/java/org/package1/services/ClassA.java c:/Users/Daniel/workspace/myproj/src/main/java/org/package1/www/services/ClassA.java c:/Users/Daniel/workspace/myproj/target/generated-sources/cxf/org/package1/services/ClassA.java But they belong to different packages: package org.package1.services; package org.package1.www.services; So, why would the compiler complain about a duplicate class? (Or is it Maven that's complaining?) I am not familiar with the design considerations of the original author, so any idea how to resolve these duplicates would be much appreciated. java maven m2e share|improve this question asked Dec 6 '12 at 13:51 Withheld 1,80442854 add a comment| 3 Answers 3 active oldest votes up vote 4 down vote accepted You've got three classes, in two packages.

Maybe in it's own http://stackoverflow.com/questions/13745003/why-would-compiler-fail-on-duplicate-class-if-they-belong-to-different-packages file Animal.java , or just like TestHippo here in another file? When that has already been compiled and is in the path, the compiler will give this type of error. Shelly Biswal Greenhorn Posts: 17 posted 9 years ago Yes there was another class named Animal in another java class called o.java. i dnt understnd why that should affect my class animal in another java class. cant i ve same class names in two different java files??? https://coderanch.com/t/408341/java/java/Duplicate-class-Error Rob Spoor Sheriff Posts: 20677 65 I like... posted 9 years ago Originally posted by Shelly Biswal: cant i ve same class names in two different java files??? Not if they are in the same package as well. Imagine the situation where you have two (non-public) classes in two different files with the same fully qualified name (so same package etc). Then you want to use that class. But which one? That's why I put all classes of my (real, non-test) code in separate files, so this problem can never arise. Please note that you can still have the same name if they are in different packages, like java.awt.List and java.util.List, or if they are in the any package but at least one of them is a nested class like javax.swing.text.html.Parser and javax.swing.text.html.HTMLEditorKit.Parser. The first is a top level class, the second is a nested class inside top level class HTMLEditorKit.
