不能讓JUnit的工作（assertThat/hasItem）

Question

我剛剛創建了一個虛擬的Maven項目：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> 
    <modelVersion>4.0.0</modelVersion> 

    <groupId>com.loki2302</groupId> 
    <artifactId>junit-test-app</artifactId> 
    <version>0.0.1-SNAPSHOT</version> 
    <packaging>jar</packaging> 

    <name>junit-test-app</name> 
    <url>http://maven.apache.org</url> 

    <properties> 
     <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> 
    </properties> 

    <dependencies> 
     <dependency> 
      <groupId>junit</groupId> 
      <artifactId>junit</artifactId> 
      <version>4.10</version> 
      <scope>test</scope> 
     </dependency> 
    </dependencies> 
</project> 

我在這個項目中唯一的測試：

package com.loki2302; 

import java.util.Arrays; 
import java.util.List; 

import org.junit.Test; // for @Test annotation 
import static org.junit.Assert.*; // for assertThat() 
import static org.junit.matchers.JUnitMatchers.*; // for hasItem() 

public class AppTest { 
    @Test 
    public void sillyTest() { 
     List<Integer> list = Arrays.asList(123, 456); 
     assertThat(list, hasItem(123)); 
    } 
} 

當我運行mvn clean test，它說：

Maven的版本：

D:\junit-test-app>mvn --version 
Apache Maven 3.0.3 (r1075438; 2011-02-28 20:31:09+0300) 
Maven home: D:\apache-maven-3.0.3\bin\.. 
Java version: 1.7.0, vendor: Oracle Corporation 
Java home: C:\Program Files\Java\jdk1.7.0\jre 
Default locale: en_US, platform encoding: Cp1251 
OS name: "windows 7", version: "6.1", arch: "amd64", family: "windows" 

Java版本：

D:\junit-test-app>java -version 
java version "1.7.0" 
Java(TM) SE Runtime Environment (build 1.7.0-b147) 
Java HotSpot(TM) 64-Bit Server VM (build 21.0-b17, mixed mode) 

我如何工作的呢？

更新

爲Assert和JUnitMatchers，更新的輸出固定進口mvn clean test

Answer 1

您有：

import org.junit.Assert.*; 
import org.junit.matchers.JUnitMatchers.*; 

如果你想要的是：

import static org.junit.Assert.*; 
import static org.junit.matchers.JUnitMatchers.*;
