Maven doesn't see tested classes

Question

Hello,

i have problem with maven. When i try to compile test classes (mvn test-compile), it fails to find the tested classes used in test classes. For example class UserTest can't be compiled because compiler can't find class User which is being used inside the UserTest class. The problem is most likely in the class path not including target folder during test-compile phase, which is weird because i thought maven does include it.

If anyone had any ideas how to fix this issue, i would be greatful.

The pom.xml file can be found here http://github.com/tomasherman/JBTBackup/blob/master/pom.xml, just like rest of the project.

The maven output is as follows:

Thanks for all comments, Tomas Herman

Answer 1

Did you try to invoke mvn compile test-compile, or just mvn clean install ?

Answer 2

Note that Maven already failed to compile the classes to be tested:

[INFO] [compiler:compile {execution: default-compile}]
[INFO] No sources to compile

And @Gopi's comment explains why this happened. You should put your code under src/main/java for Maven to see it by default.

Answer 3

There is no explicit import for the User class in your UserTest.java file, which implies in should be somewhere in the org.tomasherman.JBTBackup.Resource.Entity package.

However, there's no such file in either src/test/java/org/tomasherman/JBTBackup/Resource/Entity or src/main/java/org/tomasherman/JBTBackup/Resource/Entity.

I can't see anything in your POM file to generate this class potentially (like hbm2java). Maybe you've forgotten to commit it?

Answer 4

You have to move your application classes to src/main/java/... instead of src/main/resources, cause Maven assumes (convention over configuration) that your java classes are located in src/main/java. This means they will never be compiled.
