the class is not available on the command line, and a common cause cannot resolve symbol error in jsp of this is having your current working directory set to somewhere inside other packages, rather than at the project's root. cannot resolve symbol java intellij This applies if you have either no CLASSPATH set, or a CLASSPATH which has '.'

variable before attempting to use it, or you misspelled it (that includes having the incorrect case). Another possibility is that the variable is in the wrong scope, e.g.: class X { int x=5; } class Y { public static void main(String[] args) { System.out.println(x); //x cannot be resolved //now for a working version: int x=6; System.out.println(x); } } Methods -- On a method name, the same things

apply as for variable names, plus you may have given the method the wrong parameter types, e.g., calling add(int) where you should have called add(Object). You could also get this error when trying to invoke a constructor that doesn't exist or is not visible, e.g.: class X { private X(int y) { } } X x=new X(5); //this won't work, remove 'private'. X x=new X("Hello"); //this won't work, add a constructor as follows: class X { X(int y) { } public X(String string) { } } X x=new X("Hello"); //this works now. A small point with the above is that instead of just removing 'private' you should probably replace it with 'public'. Constructors -- If you called a constructor with the wrong parameters, you can get a cannot resolve symbol error, but the error will include the word 'constructor'. Check the original constructor to see what you should have used. Check the types of parameter in the API, compared to the types that you used (as reported in the compiler error message). The order of the types should be the same too. -- RickyClarkson CategoryJava View edit of May 12, 2012 or FindPage with title or text search

I setup a Maven project and add log4j as a dependency in the pom.xml file. The IDEA inspections run fine and my unit tests http://stackoverflow.com/questions/5905896/intellij-inspection-gives-cannot-resolve-symbol-but-still-compiles-code all compile and run. I then added hunnysoft's jmime library to my local maven repository using the mvn install:install-file as follows. mvn install:install-file -Dfile=jmime.jar -DgroupId=jmime \ -DartifactId=jmime -Dversion=3.1.1e -Dpackaging=jar Maven installed the jar file just fine into my local repository. I then went into IntelliJ's Settings => Maven => Repository Services and Updated my local repository (so that IntelliJ would reindex the repository contents). Finally, I added the following dependency to my pom.xml file (just above the log4j dependency).

I thought it might be an error in my code, but I couldn't find any. So I made a completely new project that would simply test out using the scanner class. No dice. I don't know what I'm cannot resolve doing wrong here. I've looked through the API in relation to the Scanner class and everything seems to check okay. import java.util.Scanner; public class ScanDemo1 { public static void main(String[] args) { Scanner sc = new Scanner(System.in); String input = sc.next(); System.out.println(input); } } When this runs, the command prompt shows: C:\java\projects>javac ScanDemo1.java ScanDemo1.java:1: cannot resolve symbol symbol : class Scanner location: package util import java.util.Scanner; ^ ScanDemo1.java:7: cannot cannot resolve symbol resolve symbol symbol : class Scanner location: class ScanDemo1 Scanner sc = new Scanner(System.in); ^ ScanDemo1.java:7: cannot resolve symbol symbol : class Scanner location: class ScanDemo1 Scanner sc = new Scanner(System.in); ^ 3 errors C:\java\projects> I don't really understand where the compiler is having trouble. Any suggestions? NOTE: When posting this, I realized the arrows wouldn't point to what I was seeing, and would instead go to the beginning of the line. I made the letters that the arrows were pointing at BOLD so that you'd see what I was seeing. Except, on the third arrow, I tried making the equals sign (=) bold, but that didn't seem to do much. So, on the third error, the arrow is pointing at the equals sign. Thanks a ton! Carpe diem, because every day is worth living to its fullest.

I don't fully understand what went on during that post. Do you think my classpath might be incorrect? Everything else java related seems to run flawlessly until I try out the scanner class. Is it possible that when I say:

I do not have the java file for the class. When I use the class in the java file that contains main(), it gave me the "Cannot resolve symbol" error. How can I fix the problem? Thanks a lot.

The folder is inside out\production folder. But after I put the class with other classes, the error is still there. How can I let IDEA know there is a new class?

Assuming this is a standalone class you'll need to stick it in a directory of its own, ensuring its location in that directory (that is the directory path) matches its package. Then attach that folder as a class folder. It is unusual to import a single class into code, which is why this may sound a long winded way of doing it.
