java : cannot resolve symbol

I was compiling an JAVA ( 1.4 varsion )file and was getting the following error (about 100 times all are same).

Appli.java:721: cannot resolve symbol
symbol  : class License
location: class test.App.Appli
            License  sellLicense = sell.getLicense();

I used

   run/cmd/cd D:...../javac Appli.java

I had set the CLASSPATH variable, to the Classes folder of the java files I am presently running.

  Control panel/Settings/System/System Prop开发者_开发技巧erties /Advanced/Environmental Variables/System Variables/ Add/CLASSPATH 

Should I use

How to solve the issue?

It looks to me like you need to compile the class License with the class Appli. Take a look at the Javac Documentation for more details, but you can do something like the following:

javac Appli.java License.java

If License is in a library, you will need to add the library to your compilation classpath. This is done with the -classpath flag:

javac -classpath "classpath" Appli.java

You are probably missing an import statement.

You need to set the CLASSPATH and make sure that you are in the correct directory.

Assuming that test.App.Appl is trying to reference test.App.License, the directory structure should be:

/somedir/test
/somedir/test/App
/somedir/test/App/Appl.java
/somedir/test/App/License.java

You should set $CLASSPATH to "/somedir", then change your current directory to /somedir and run the compiler as javac test/App/*.java; e.g.

$ export CLASSPATH="/somedir"
$ cd /somedir
$ javac test/App/*.java

You can also use the -cp command line option with the javac (and later the java) command, and you run the javac compiler from a different directory by using the -sourcepath option.

The other possibility is that the package for License is not test.App. If that is the case, you need to adjust the directory structure to match the package naming, and add an import statement to the Appl class.

EDIT: If you notice a build.xml or pom.xml (or possibly even a Makefile) in the source tree, you probably should not be using javac directly. A build.xml is for building using Ant, a 'pom.xmlis for Maven (or Ivy) and aMakefileormakefileis formake`.
