When I am trying to build it using Eclipse it is giving me 2 errors

The type java.util.Map$Entry cannot be resolved. It is indirectly referenced from required .class files

The type java.util.Comparator cannot be resolved. It is indirectly referenced from required .class files

I have tried to turn off Build Automatically in Project Menu then Clean all the Project and again turn on the Build Automatically. But it doesn't work.

Answer 1

You might probably be using Java 8which is not supported by Liferay version 6. Use Java 6 or 7 and re run the service builder, then it should work fine. From Properties of your project in eclipse you can change the Java Compiler level. Have a look here.
