Maven：找不到符号

Question

I am attempting to run Maven builds of a Java project, however tests are failing stating that the Player symbol cannot be founded, despite being imported.

Maven builds are failing as follows:

In your Maven-compiler-plugin definition:

        <plugin>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.3</version>
            <configuration>
                <includes>
                    <include>src</include>
                </includes>
            </configuration>
        </plugin>

Do not include the src folder directly. It will mess up the compilation order, Maven ends up building the test folder first, then fails on missing the main classes. Change it to this to make it work:

        <plugin>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.3</version>
        </plugin>
