In addition to the already suggested cause of missing a class file this error can also indicate a duplicate class file  eclipse reports this error when an class file on the build path uses another class that has multiple definitions in the build path

If you still can not find anything wrong with your setup  you can try Project -  Clean and clean all the projects in the workspace   EDIT  Sorry  did not see the suggestion of verbose mode     same thing

In my case it was a result of my adding a new dependency to my pom xml file    The new dependency depended on an old version of a library  2 5   That same library was required by another library in my pom xml  but it required version 3 0    For some reason  when Maven encounters these conflicts it simply omits the most recent version  In Eclipse when viewing pom xml you can select the  dependency hierarchy  tab at the bottom to see how dependencies are resolved  Here you will find if the library  and thus class  in question has been omitted for this reason   In my case it was as simple as locking down the newer version  You can do so by right-clicking the entry - there is an option to lock it down in the context menu

It means   A class that you use needs another class that is not on the classpath   You should make sure  as Harry Joy suggests  to add the required jar to the classpath

This error occurs when the classes in the jar file does not follow the same structure as of the folder structure of the jar    e g  if you class file has package com test exam and the classes jar created out of this class file has structure test exam    error will be thrown  You need to correct the package structure of your classes jar and then include it in ecplipse build path

It sounds like this has been a known issue  Bug 67414 that was resolved in 3 0     someone has commented that it s occurring for them in 3 4 as well    In the mean time  the work around is to remove the JRE System Library from the project and then add it back again    Here are the steps    Go to properties of project with the build error  right click   Properties   View the  Libraries  tab in the  Build Path  section  Find the  JRE System Library  in the list  if this is missing then this error message is not an eclipse bug but a mis-configured project   Remove the  JRE System Library   Hit  Add Library       Select  JRE System Library  and add the appropriate JRE for the project  eg   Workspace default JRE    Hit  Finish  in the library selection and  OK  in the project properties and then wait for the re-build of the project  Hopefully the error will be resolved

I had an interesting case of this problem with Eclipse 4 4 2  My project  P1  referenced an external class  project P2  with two methods with the same name but different argument types   public static void setItem Integer id      public static void setItem Item item        The type Item was contained in a third project P3  which I did not want to be visible here  P1 called only the first method   ExternalClass setItem Integer valueOf 12345      So the second method  which used the Item class  was not used  and it is true that P3 was not in the compilation classpath     why should it if it is not used   Still Eclipse told me  The type    Item cannot be resolved  It is indirectly referenced from required  class files   Compiling from the command line did not produce any such issues  Changing the name of the second method  unused here   made the problem go away in Eclipse  too

This is as likely a matter of Eclipse s getting confused as it is an actual error   I ignored the error and ran the web service whose endpointInterface it complained about  and it ran fine  except for having to deal with the dialog every time I wanted to run it   Just another opaque error that tells me nothing

Since you give us very little details  most likely what you did  which is an incredibly easy mistake to make  is that instead of heading to   Build Path  gt  Configure Build Path  gt  Projects   and adding your additional project folder from there  instead you went to  Build Path  gt  Configure Build Path  gt  Libraries   and added your project folder from there instead   This is most definitely the case if your code is all correct  but upon automatically reorganizing imports via the ctrl space shortcut   instead of your import statements referring to com your additionalproject  your references all point to bin com your additionalproject    Note the bin  Meaning that you -are- indirectly referring to your class by treating your other project folder structure as a library  making your IDE doing all the wokr of finding the exactly binary class you re referring to   To correct this  remove the folder from the Libraries  and instead add it under the Projects tab  and reorganize your imports  Your project should work fine

For me none of the solutions above worked  What worked for me was to select all the code in the class  then convert it to a comment  save  then convert it back to normal text  the error was gone

In my case  I created a project and made its minSdkVersion 9 and targetSdkVersion 17  I used automatically generated libs android-support-v4 jar  I also had to make use of ActionBarActivity using android-support-v7-appcomapt jar  So I just copied the android-support-v7-appcompat jar file from android-sdk extras andrid support v7 appcompat libs folder and pasted it to my project libs folder  And this caused the above error   So basically I needed to put android-support-v4 jar file from android-sdk extras andrid support v7 appcompat libs as well to my project libs folder  As per my knowledge the v7 jar file had dependencies on v4 jar file  So  it needed it own v4 jarfile instead of my project automatically created v4 jar file
