Java: Unresolved compilation problem

Java: Unresolved compilation problem

(rewritten 2015-07-28)

The default behavior of Eclipse when compiling code with errors in it, is to generate byte code throwing the exception you see, allowing the program to be run. This is possible as Eclipse uses its own built-in compiler, instead of javac from the JDK which Apache Maven uses, and which fails the compilation completely for errors. If you use Eclipse on a Maven project which you are also working with using the command line mvn command, this may happen.

The cure is to fix the errors and recompile, before running again.

The setting is marked with a red box in this screendump:


try to clean the eclipse project

Java: Unresolved compilation problem

you just try to clean maven by command

mvn clean

and after that following command

mvn eclipse:clean eclipse:eclipse

and rebuild your project….
