Eclipse The declared package does not match the expected package

Question

I have a problem importing an external project  I go File -  Import    -  Existing Projects into Workspace  choose the folder where the project is located and everything is imported - but the package names of the project don t seem to be what Eclipse expects  The package names all have a prefix   prefix packagename1 prefix packagename2   etc   But Eclipse expects  src prefix1 prefix packagename1 src prefix1 prefix packagename2   etc  because the directory is src prefix1 prefix package1  I don t really want to mess around with external code  How do I tell Eclipse to ignore the directory  src prefix1   Or what else can I do

I get this problem in Eclipse sometimes when importing an Android project that does not have a  classpath file    The one that Eclipse creates is not exactly the same one that Android expects   But  the Android  classpath files are usually all relative  so I just copy a correct  classpath file from another project over the incorrect  classpath   I ve created a video that shows how I do this  https   www youtube com watch v IVIhgeahS1Ynto

I happened to have the same problem just now  However  the first few answers don t work for me I propose a solution change the  classpath file For example you can define the classpathentry node s path like this  path  src prefix1 java  or path  src prefix1 resources   Hope it can help

The only thing that worked for me is deleting the project and then importing it again  Works like a charm

Go to src folder of the project and copy all the code from it to some temporary location and build the project  And now copy the actual code from temporary location to project src  And run the build again  Problem will be resolved   Note  This is specific to eclipse

I just ran into this problem  and since Mr  Skeet s solution did not work for me  I ll share how I solved this problem   It turns out that I opened the java file under the  src  before declaring it a source directory   After right clicking on the  src  directory in eclipse  selecting  build path   and then  Use as Source Folder   Close and reopen the already opened java file  F5 refreshing it did not work    Provided the path to the java file from  prefix1  onwards lines up with the package in the file  example from the requester s question prefix1 prefix packagename2   This should work  Eclipse should no longer complain about  src

Suppose your project has a package like package name1 name2 name3 name4   declared package   Your package explorer shows package top level named name1 name2 sub packages named name3 name4  You will have errors because Eclipse extracts the package name from the file directory structure on disk starting at the point you import from   My case was a bit more involved  perhaps because I was using a symbolic link to a folder outside my workspace     I first tried Build Path Java Build Path Source Tab Link Source Button Browse to the folder before name1 in your package Folder-name as you like  i think   But had issues   Then I removed the folder from the build path and tried File   Import      General   File System   click Next   From Directory   Browse    to folder above name1   click Advanced button   check Create links in workspace   click Finish button

The build path should contain the path  till before  that of the package name   For eg  if the folder structure is  src main java com example dao If the class containing the import statement package com example dao  complains of the incorrect package error  then  the build path should include src main java This should solve the issue

Right click on the external folder which is having package     src prefix1 prefix packagename1  src prefix1 prefix packagename2     Click Build path --  Remove from build path  Now go the folder prefix1 in the folder section of your project  Right click on it --  Build path --  Use as source folder  Done  The package folder wont show any error now  If it still shows  just restart the project

If you have imported an existing project  then just remove your source folders and then add them again to build path  and restart eclipse  Most of the times eclipse will keep showing the error till you restart

Just go into the build path and change the source path to be src prefix1 instead of src   It may be easiest to right-click on the src directory and select  Build Path   Remove from build path   then find the src prefix1 directory  right-click it and select  Build Path   Use as source folder

For me the issue was that I was converting an existing project to maven  created the folder structures according to the documentation and it was showing the  main  folder as part of the package   I followed the instructions similar to Jon Skeet   JWoodchuck and went into the Java build path  removed all broken build paths  and then added my build path to be  src main java  and  src test java   as well as the resources folders for each  and it resolved the issue
