Error Duplicate Class Android Studio
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 1,80952854 add a comment| 3 Answers 3 active oldest votes up vote 4 down vote accepted You've got three classes, in two packages. Therefore two of the classes are in the same package. These two files: .../myproj/src/main/java/org/package1/services/ClassA.java .../myproj/target/generated-sources

Maybe in it's own 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 https://coderanch.com/t/408341/java/java/Duplicate-class-Error 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??? Rob Spoor Sheriff Posts: 20703 68 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.

Description cmd1234 2013-02-19 16:43:26 UTC Its actually duplicate class error version 7.3 RC2 Get duplicate class error when there is no duplicate class. Program compiles up correctly with no errors. Have deleted cache files, but problem persists. When loaded into Netbeans 7.2 I have no problems at all. Comment 1 cmd1234 2013-02-19 17:09:23 UTC Got around the problem I didn't know that netbeans has two places where is caches files. had deleted ~/Library/Application\ Support/NetBeans/7.3rc2 but also need to delete ~/Library/Caches/NetBeans/7.3rc2 so its just the old cache problem. Comment 2 Tomas Danek 2013-02-27 15:31:50 UTC closing then. Comment 3 psammalisto 2013-03-22 19:19:28 UTC I got that error when I copied a backup over the file in src folder. I could find the class name only in the class file and in project properties as main.class, it cannot be found e.g. anywhere in files in ~folder. Comment 4 Tomas Danek 2013-04-10 09:14:46 UTC Did you try wiping out the cache (like ~/Library/Caches/NetBeans/7.3 ) ? (In reply to comment #3) > I got that error when I copied a backup

Sorry There was an error emailing this page. Comments JavaWorld | Feb 10, 2010 8:16 PM PT Comments Developers who are new to Java can sometimes have trouble with class and package naming. In fact, the introductory Java forums are filled with threads starting with questions about these areas of Java. In this blog post, I look at some of these errors and some of the causes of these errors.One of the more obvious errors occurs when a public Java class is named differently than the file that contains the class definition.This is demonstrated in the next screen snapshot. In this example, a class was declared as public with the name Person, but was saved in a file called Person2.java. The error message is pretty explicit: "class Person is public, should be declared in a file named Person.java" The "duplicate class" error can sometimes be a little more tricky to
