错误：软件包org.junit不存在

Question

I keep getting these errors when i am trying to run my ant file.

  [javac] Compiling 8 source files to C:\\Users\\FaradaysCage\\git\\mancala\\build [javac] C:\\Users\\FaradaysCage\\git\\mancala\\src\\tests\\BoardDataTest.java:1: error: package org.junit does not exist [javac] import static org.junit.Assert.assertEquals; [javac] ^ [javac] C:\\Users\\FaradaysCage\\git\\mancala\\src\\tests\\BoardDataTest.java:1: error: static import only from classes and interfaces [javac] import static org.junit.Assert.assertEquals; [javac] ^ [javac] C:\\Users\\FaradaysCage\\git\\mancala\\src\\tests\\BoardDataTest.java:2: error: package org.junit does not exist [javac] import org.junit.Test; [javac] ^ [javac] C:\\Users\\FaradaysCage\\git\\mancala\\src\\tests\\BoardDataTest.java:8: error: cannot find symbol [javac] @Test 

This is my ant build file

<project name="Mancala" default="fullBuild" basedir=".">
    <description>

    and distribution. Will also include automated testing and
    generation of documentation.

</project>

I know that somehow I am not including junit.jar into my build, but it should be being included because of in my path id, and I am at my wits end about what is wrong.

Thank you in advance

Answer 1

The <javac> task that creates the tests needs a classpath:

<javac srcdir="${test}" destdir="${build.test}" classpathref="junit.class.path" />

By the way, the following doesn't look right:

<junit printsummary="on" fork="true" haltonfailure="yes">
    <classpath>
        <classpath refid="junit.class.path" />
        <pathelement location="${build.test}" />
        <formatter type="plain" />
        <batchtest todir="${test.report}">
            <fileset dir="${test}">
                <include name="**/*Test*.java" />
            </fileset>
        </batchtest>
    </classpath>
</junit>

The <formatter> and <batchtest> elements shouldn't be nested under a <classpath> . They should be directly under <junit> . It should be more like:

<junit printsummary="on" fork="true" haltonfailure="yes">
    <classpath>
        <classpath refid="junit.class.path" />
        <pathelement location="${build.test}" />
    </classpath>
    <formatter type="plain" />
    <batchtest todir="${test.report}">
        <fileset dir="${test}">
            <include name="**/*Test*.java" />
        </fileset>
    </batchtest>
</junit>
