AntBuilder找不到包org.junit

我在Eclipse的项目中使用“JUnit测试用例”新文件对话框将一些单元测试添加到测试目录（与我的src目录并行）。我有两个构建器，默认的Java Builder和我添加的AntBuilder。 Java Builder继续工作，但AntBuilder在Eclipse中失败。当我选择项目 - >生成所有，它会显示这样的：AntBuilder找不到包org.junit

Buildfile: C:\source\machine-paint\eclipse\machine-paint\src\build.xml 
clean: 
     [delete] Deleting directory C:\source\machine-paint\eclipse\machine-paint\build 
compile: 
     [mkdir] Created dir: C:\source\machine-paint\eclipse\machine-paint\build\classes 
     [javac] Compiling 33 source files to C:\source\machine-paint\eclipse\machine-paint\build\classes 
     [javac] C:\source\machine-paint\eclipse\machine-paint\test\stencil\BorderWalkerTest.java:3: error: package org.junit does not exist 
     [javac] import static org.junit.Assert.*; 
     [javac]      ^

，然后经过几次类似的错误，这样的：

[javac] C:\source\machine-paint\eclipse\machine-paint\test\stencil\BorderWalkerTest.java:8: error: incompatible types 
     [javac] @Test 
     [javac] ^
     [javac] required: Annotation 
     [javac] found: Test

这是我的构建文件。在这一点上，我真的在黑暗中开火，比如将类路径标记添加到javac命令。

<?xml version="1.0" encoding="UTF-8"?> 
<project name="Builder" default="jar" basedir="."> 
    <target name="clean"> 
    <delete dir="build"/> 
    </target> 
    <target name="compile" depends="clean"> 
    <mkdir dir="build/classes" /> 
    <javac srcdir="." destdir="build/classes" debug="true" includeantruntime="true"> 
     <classpath> 
     <path id="org.junit" location="c:/eclipse/plugins/org.apache.ant_1.8.3.v20120321-1730/lib/junit.jar" /> 
     </classpath> 
    </javac> 
    </target> 
    <target name="jar" depends="compile"> 
    <jar destfile="../../stencil.jar" basedir="build/classes"> 
     <manifest> 
     <attribute name="Main-Class" value="stencil.Main" /> 
     </manifest> 
    </jar> 
    <copy file="../../stencil.jar" tofile="../../../robotsdoart/stencils/stencil.jar" /> 
    </target> 
    <target name="run"> 
    <java jar="build/jar/stencil.jar" fork="true" /> 
    </target> 
</project>

回答：

尝试将srcdir更改为实际源目录，以便它不包含测试。

喜欢的东西：

<javac srcdir="src/" destdir="build/classes" debug="true" includeantruntime="true"> 
    <classpath> 
    <path id="org.junit" location="c:/eclipse/plugins/org.apache.ant_1.8.3.v20120321-1730/lib/junit.jar" /> <!-- not sure if you need this --> 
    </classpath> 
</javac>

回答：

尝试直接包括您的junit jar文件。还要确保JAR文件在该位置可用。

<javac 
    srcdir="." 
    destdir="build/classes" 
    debug="true" 
    includeantruntime="true" 
    classpath="c:/eclipse/plugins/org.apache.ant_1.8.3.v20120321-1730/lib/junit.jar" 
/>

或定义path元素：

<path id="lib.path.id"> 
    <fileset dir="c:/eclipse/plugins/org.apache.ant_1.8.3.v20120321-1730/lib" 
      includes="junit.jar"/> 
</path>

，并使用相同的javac为

<javac 
    srcdir="." 
    destdir="build/classes" 
    debug="true" 
    includeantruntime="true" 
    classpathref="lib.path.id"" 
/>

希望这有助于。
