Q:

mvn test doesn't work. it only shows 'BUILD SUCCESS'

I'm stuck in this problem. I'm trying to test this project with maven. I typed 'mvn test', 'mvn test-compile', 'mvn package' and so on. But it always shows same output like this:
[INFO] Scanning for projects...
[INFO]

A:

Tests may be performed by the Surefire Maven plugin and its test goal.
Maven has a number of consecutive lifecycle phases. One of them is the test phase, which would be a good phase to perform tests.
Now, goals and phases need to be bound together. You may bind them yourself, using an execution:
<plugin>
    <artifactId>maven-surefire-plugin</artifactId>
    <executions>
        <id>...</id>
        <goals>
            <goal>test</goal>
        </goals>
        <phase>test</phase>
       ...
    </executions>
</plugin>

There are also default (built-in) lifecycle mappings for common goals. Depending  on the type of project (packaging) different default mappings are applicable.
Packaging jar will bind surefire:test to the test phase. Packaging pom won't, which is why your particular expectations aren't met.
Your options here are either:

Add an execution for the Surefire plugin
Convert your project to another packaging type

If your project has Java code on board (which the reference to maven-compiler-plugin suggests), converting it to packaging jar may be appropriate. If you're sure this should not be a jar project, there is nothing wrong with defining your desired executions. If you want to go very fancy, you may introduce your own packaging type with its subsequent lifecycle mappings.

A:

The packaging of your project is pom. If your project contains Java source code, it will not be compiled.
Change the packaging instead to jar and it will do what you expect.
