我无法让JUnit处理简单的Java示例

Question

我无法让这个JUnit测试工作在我正在研究的这个简单的Java示例上。 它在Eclipse内部工作，但不能从命令行... mvn test

这是我的测试代码：

import junit.framework.Assert;
import org.junit.Test;
import org.runnablejar.TestJAR.App;


public class TestApp {
    @Test
    public void testPrintHelloWorld() {

        Assert.assertEquals(App.getHelloWorld(), "Hello Worl");

    }
}

这是我的测试输出：

您需要将maven-compiler-plugin配置为使用1.5或1.6。

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <configuration>
        <source>1.6</source>
        <target>1.6</target>
    </configuration>
</plugin>
