Java AntBuilder可以'；找不到包org.junit

我使用“JUnit测试用例”新文件对话框在Eclipse中的项目中将一些单元测试添加到测试目录（与src目录并行）。我有两个构建器，默认的Java构建器和我添加的AntBuilder。Java构建器继续工作，但AntBuilder在Eclipse中失败。当我选择Project->Build All时，它会显示以下内容：

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]                        ^

在出现一些类似错误后，这：

 [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，我真的是在黑暗中开火，比如将classpath标记添加到javac命令中

<?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>

尝试直接包含您的

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"
 />

并在

javac

中使用相同的

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

---

尝试将srcdir更改为实际的源目录，使其不包含测试

比如：

<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>

创建path元素并在javac中引用该id会有所帮助

<path id="lib.path.id.junit.jar">
    <fileset dir="${project-path}\lib" includes="*.jar" />
</path>



然后我使用classpathref在javac中引用了它

<target name="compile" depends="copy" description="compile all the source files in both src and test directories and should store all the class files in the bin directory.">
    <javac destdir="bin" includes="*.java" classpathref="lib.path.id.junit.jar" includeantruntime="true" debug="true" >
        <src path="src" /> 
        <src path="test" />
    </javac>

</target>

恐怕不行。我开始怀疑我是不是一开始就把它指向了错误的junit.jar文件或其他什么。我已经提到过：）
还要确保jar文件在该位置可用。
我将其更改为
<target name="compile" depends="copy" description="compile all the source files in both src and test directories and should store all the class files in the bin directory.">
    <javac destdir="bin" includes="*.java" classpathref="lib.path.id.junit.jar" includeantruntime="true" debug="true" >
        <src path="src" /> 
        <src path="test" />
    </javac>

</target>
