helping each other. Join them; it only takes a minute: Sign up Why would compiler fail on duplicate class if they belong to different packages? up vote 0 down vote favorite I got this inherited project using Maven/m2e as the build automation tool. All nice & cool except that this project, checked out of SVN as is, java duplicate class error 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. 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/cxf/org/package1/services/ClassA.java ... are both contributing org.package1.services.ClassA (which is the fully-qualified class name the compiler is complaining about, note). It's not clear which one yo

Yes, Right ? –sᴜʀᴇsʜ ᴀᴛᴛᴀ Oct 11 '13 at 12:57 Its the only class file in my project.

Description debopamg 2011-04-22 05:12:46 UTC Product Version = NetBeans IDE 7.0 RC1 (Build 201103280000) Operating System = Linux version 2.6.35-28-generic running on i386 Java; VM; Vendor = 1.6.0_24 Runtime = Java HotSpot(TM) Client VM 19.1-b02 There was a git merge conflict, and after resolving it (outside the IDE, using Meld), I find that the IDE is reporting the conflicted class as Duplicate class. I am using the GIT plugin. Comment 1 Ondrej Vrabec 2011-05-17 09:39:11 UTC What does it mean "Duplicate class"? Can you make a screenshot? Comment 2 Ondrej Vrabec 2011-05-19 08:19:36 UTC Please explain further Comment 3 debopamg 2011-05-19 09:29:47 UTC The problem occurs under the following circumstances: 1. the netbeans git plugin is installed 2. a merge/rebase is performed with the remote git repo 3. there is a conflict in one of the files 4. the conflict is resolved using an external tool (like Meld) 4. after the conflict is resolved, and the change commited, netbeans shows Duplicate class error for the class for which there was a conflict. Hope that
