Obviously there are cases where there is a valid issue however Eclipse throws this error for no good reason sometimes. This is still (in v 2020-09) an old (2010) Eclipse bug that can be resolved by making a negligible change to the project settings.

touch .classpath

solves the issue, or go to Project > Properties > Java Build Path > Order and Export > make a meaningless order change > Apply. Changing the order back does not regress to the problem.

I couldn t import as well  Took me some hours to figure out  that I tried to use a 1 6 bound library jar  while I was trying to compile for 1 8  When I switched my project also to use 1 6  the import issue has gone  All error messages were leading into wrong directions  Just in the source I found some limitations directing to 1 6 version   And   For example the  settings and  classpath  File-Search   -  org eclipse jdt core compiler codegen targetPlatform 1 6  can give a hint  on such issues

If you re developing plugins in eclipse and you re using a target platform  which was my case  you need to make sure you check the target s platform configuration from Window- Preferences- Plug-in Development- Target Platform and make sure your target platform is checked and configured  Hope this helps

I had a similar problem on an import statement not resolving  I tried many of the solutions offered in this discussion  but none of them solved my problem   I eventually figured out what was happening in my case so I ll share what I discovered  If you add a jar to your build path and that jar is an OSGI bundle  a jar with a MANIFEST MF file containing OSGI header statements   you cannot import any packages from that jar until you satisfy all Import-Packages requirements  Your only clue that this is happening is that you can t import packages from that bundle  even though it looks like the library is properly included in your project build path  Optional imported packages still need to be satisfied at compile time  Optional packages are allowed to be missing at runtime  Well that s for sure true if you re using the bundle in a OSGI framework  I m not sure if that s true if you not using the bundle in a OSGI framework

I found the problem  It was the hibernate3 jar  I don t know why it was not well extracted from the  zip  maybe corrupt  A good way to check if jars are corrupt or not is navigating through their tree structure in  Project Explorer  in Eclipse  if you can t expand a jar node probably it s corrupt  I ve seen that having corrupt packages it s frequent when you drag and drop them to the  Project Explorer   Maybe it s better to move and copy them in the OS environment  Thankyou all

I had the same problem because I added a jar I created  where I had set the packaging base directory other than the base directory of the classes  As a result the class e g  java util List had to be imported as util List although the suggested import was the first one   Check the imported jars under referenced libraries to see that they are imported correctly

For Eclim   Maven users     Open the  classpath file of your project    vim  classpath  Within vim  use  MvnRepo to initialize the Maven Eclim plugin   This will set M2 REPO   Note that this step  has to be performed while editing the  classpath file  hence step  1   Update the list of dependencies with  Mvn dependency resolve  Update the  classpath with  Mvn eclipse eclipse  Save and exit the  classpath      wq  Restarting eclim seems to help   Note that steps 3 and 4 can be done outside vim  with mvn dependency resolve and mvn eclipse eclipse  respectively  Since the plugin is mentioned as an Eclipse plugin in Eclim   s documentation  I assume this procedure may also work for Eclipse users

For me  it seemed I was adding the wrong level of the library s folder  I downloaded the Jericho HTML Parser  unzipped it into  eclipse-workspace libraries jericho-html-3 4   Then when adding this as an external library folder  the trick was to navigate to that folder  highlight the  classes  folder and press Open  I had previously tried adding both the parent and various levels of subfolders and it didn t work   This is pretty much explained here  it says      You can also add a class folder  a directory containing Java class   files that are not in a JAR    There are two lessons learnt here for me  apologies if these are off-topic    Read the instructions carefully - as in word-by-word  Do not give up - this it the first time I am adding a library  it took me around two hours to get it added
