为什么JUnit测试在Ant Build System中失败？

我是Java新手，所以请对我温柔。我正在尝试Ant构建系统来运行我的JUnit测试。但是当我在没有Ant的情况下运行我的测试时，它会通过，但是当我使用Ant Build来运行我的JUnit测试时，测试失败。为什么JUnit测试在Ant Build System中失败？

这里是我的Ant build.xml文件：

<property name="lib.dir" value="lib"/> 

<path id="classpath"> 
    <fileset dir="${lib.dir}" includes="*.jar"/> 
</path> 

<target name="runjunit" depends="compile"> 
    <mkdir dir="reports" /> 
    <junit printsummary="true" showoutput="yes" haltonerror="yes" haltonfailure="yes" > 
     <test name="com.geometry.CartesianPositionTest" /> 
     <classpath> 
      <path refid="classpath" /> 
      <pathelement location="out" /> 
     </classpath> 
    </junit> 
</target> 

<target name="compile"> 
    <javac srcdir="src" destdir="out" includeantruntime="false" classpath="lib/junit-4.11.jar"/> 
</target> 

<target name="package" depends="compile"> 
    <jar destfile="geometry.jar" 
     basedir="out" 
     includes="**" 
     excludes="**/*Test*" > 
     <manifest> 
      <attribute name="Main-Class" value="com.geometry.CartesianPosition" /> 
     </manifest> 
    </jar> 
</target>

和Ant构建的堆栈跟踪是：

Ant build completed with 3 errors and no warnings in 0s at 20/07/15 6:15 PM

测试文件是：

package com.geometry; 

import org.junit.Test; 
import java.util.Arrays; 
import static org.junit.Assert.assertEquals; 


public class CartesianPositionTest { 

    @Test 
    public void testShouldReturnTheEndPointsOfLine() throws Exception { 
     CartesianPosition position = new CartesianPosition(0, 0, 0, 0); 

     assertEquals(Arrays.asList(0, 0, 1, 1), position.getPositions()); 
    } 

    @Test 
    public void testCheckForLengthBetweenZeroAndOne() throws Exception { 
     CartesianPosition line = new CartesianPosition(0, 0, 1, 1); 

     assertEquals(1, line.length()); 
    } 
}

和主要文件是：

package com.geometry; 

import java.util.ArrayList; 

public class CartesianPosition { 

    private int x1, y1, x2, y2; 
    public int length; 



    public CartesianPosition(int positionX1, int positionY1, int positionX2, int positionY2) { 
     this.x1 = positionX1; 
     this.y1 = positionY1; 

     this.x2 = positionX2; 
     this.y2 = positionY2; 
    } 

    public Object getPositions() { 
     ArrayList<Integer> list = new ArrayList<Integer>(); 
     list.add (0); 
     list.add (0); 
     list.add (1); 
     list.add (1); 
     return list; 
    } 

    public int length() { 
     return 1; 
    } 
}

http://stackoverflow.com/questions/7850847/junit-test-fails-in-ant-with-junit-task-but-passes-with-exec的可能的复制 – Codebender

我认为那是不同的，试图这样，但它不起作用。这是因为我只通过JUnit从命令行以及IDEA IDE尝试它，它工作。但是当我使用shell或IDE来运行Ant脚本时，这两种方式都失败了。 –

Codebender是正确的。即使这不是一个可能的重复，原因也与丢失的JAR或类路径问题有关。 – Geek

我设法得到它与下面的构建文件的工作。 Ant试图将它作为junit 3样式测试而不是4个。我相信这是因为语言级别违约1.5。我还必须编译测试。之后，org/hamcrest/SelfDescribing出现NoClassDef错误。这是通过添加hamcrest jar来解决的。

如何解决：

将源代码版本在1.5以上
编译测试类
添加hamcrest-all-1.3.jar到lib

的build.xml
