I completely uninstalled IntelliJ and have now reinstalled and imported my project. I imported using gradle and can see all of the files in my project present. However, when I open a file I can't find any declaration to go to by doing cmd + click. I have the Java 7 SDK setup, and I can't even go to the declaration of classes in my own project. Going to a Java core class like String
or List
doesn't work either. How can I enable the IDE to be able to find my classes?
I'm on OSX Yosemite, IntelliJ 2016.1.2 build 145.972.

Same Problem for Python Project!!!
I tried to make a clean new intellij project and updated everything. Tried different virtualenvs but nothing worked out.
UNTIL I uninstalled the Python Plugin + Restart IntelliJ + Intall Python Plugin + Restart IntelliJ again. I'm not sure if this is a "real" solution, but it solved my issue.
Maybe you can try something familar for Java "Plugin"/JDK?
I faced the same issue and spent almost 15-16 tiring hours to clean, rebuild, invalidate-cache, upgrade Idea from 16.3 to 17.2, all in vain. We have a Maven managed project and the build used to be successful but just couldn't navigate between declaration/implementations as Idea couldn't see the files.
After endlessly trying to fix this, it finally dawned to me that it's the IDEA settings causing all the headache. This is what I did (Windows system):
.iml
files from project directory del /s /q "C:\Dev\trunk\*.iml".idea
folders<user_home>\.IntelliJIdea2017.2\system
VOILAAAAAAAAAAAA...!! I hope this helps a poor soul in pain
One of the reason can be that it is not able to detect the pom.xml(or gradle file) and thats why not able to set it as a maven project(or gradle).
You can manually set it up as a maven(or gradle) project by selecting your pom.xml(or gradle file)
I was having similar issues in my IntelliJ mvn project. Pom.xml was not recognized. What worked for me was right click on the pom.xml and then add as a maven project.
In my case, I just updated my IntelliJ to Ultimate 2018.2 and all of my projects suddenly cannot find the implementations and the 'src' folders - it turned out IntelliJ removed the type of project (e.g. Maven).
What I did is:
Right click on the root project > Add Framework support... > Look for Maven (in my case) > Wait to re-index again > Then it worked again.
UPDATE 2:
I have always been encountering this when I update IntelliJ (2019.1.1 Ultimate Edition).
Just click the refresh button of Maven Tab and it should re-index your current project as Maven Project:
Came across the same issue and in my case (Java project), I had to include all the dependent jars in the project's libraries section.
File -> Project Structure -> Libraries
I had to add my project dependent jars in the above section (for example; project/web/lib/). After doing so, all resolved fine. I hope this will help someone.
In my case, none of the above helped. Only upgrade of Intellij from 2017.3 to 2018.2 helped.
Do not try 2018.1 as it had a bug wherein the Find files popup would not come up.
Ensure that the directory which contains your compiled classes and libraries is marked as sources Root.
I found this cannot find declaration to go to
problem once in my Maven project. The reason for this was just that one of the sub-projects in my project did not import as maven project correctly.
For what its worth, in Pycharm it is: Right click on the root folder->Mark Directory as-> Sources Root
In my case I was using a gradle project with subprojects. The reason IntelliJ couldn't find declarations was that the subprojects were not built.
After investigating why subprojects were not built, I found out that using "auto-import" was breaking the subprojects.
After importing the project from build.gradle
without auto-import, it worked for me.
Right-click on your src folder and choose the option "mark directory as" --"Source root" and along with it again right-click on your project and choose "reformat code"(under this choose cleanup code too) and that will work fine.
If you are new to IntelliJ u May take some time to understand IntelliJ. If a Code has written in Java and using cucumber framework then we have two main files -
Goal : what are things we have defined in feature file it must be navigate towards Step Definition File. (Ctrl +click ) Note :feature file has to contain some colourful gherkins keywords too .if it’s not follow the below steps
Solution : go to file >>settings >> plugins - search “Cucumber for Java” Add the plugin restart IntelliJ it will work for sure .
I had the same issue with idea and I was trying to open a maven project but the pom files where not identified. So right clicking on the pom file and choosing "add as maven project" did all the magic for me :)
I too faced this issue. I've tried the solutions mentioned here. The issue seems not with the source folder.
For me the issue occurred when I installed a new version of IntelliJ, was using 2019 version moved to 2020 version. The project got opened in the new version but the declarations were missing.
I fixed this by :
- File>Project Structure. - Under Project Settings go to Modules. Here you should see the different project folders, for me it was not there. - Click the + button on top and click Import Module. - Select the root pom.xml and wait for the indexing to complete.
After the indexing is done all the declarations were working.
Most of the times there has been a problem with building the cache of the IDE, or something related.
Most probably, File -> Invalidate Caches / Restart
, will resolve this problem, just let the IDE finalize it's caching.
IDEA may ignore some of your maven dependency files. The "External Libraries" node in your project structure might be empty or incomplete.

Had the same problem. But only on my own methods.
Just fixed it by invalidating cache: (File-> Invalidate Caches/Restart)
I had similar issue with Goland JetBrain and what worked for me is similar to what @user8382868 said but I only closed the IDE, renamed the folder .idea
file to .idea.old
and after re-opening the project everything worked.
Your source folders where your Symbols are (Classes) are need to be configured as "Content Root".
Once done you should be able to navigate to your symbols.
