Yet another Ant + JUnit classpath problem
提问by DeX3
I'm developing an Eclipse SWT application using Eclipse. There are also some JUnit 4 tests, which test some DAO's. But when I try to run the tests via an ant build, all of the tests fail, because the test classes aren't found.
我正在使用 Eclipse 开发 Eclipse SWT 应用程序。还有一些 JUnit 4 测试，用于测试一些 DAO。但是当我尝试通过 ant 构建运行测试时，所有测试都失败了，因为没有找到测试类。
Google brought up about a million of people who all have the same problem, but none of their solutions seem to work for me -.- .
谷歌提出了大约一百万人都有同样的问题，但他们的解决方案似乎都不适合我-.-。
These are the contents of my build.xml file:
这些是我的 build.xml 文件的内容：
<property name="test.reports" value="./test/reports" />
<property name="classes" value="build" />
<path id="project.classpath">
<pathelement location="${classes}" />
</path>
<target name="testreport">
<mkdir dir="${test.reports}" />
<junit fork="yes" printsummary="no" haltonfailure="no">
<batchtest fork="yes" todir="${test.reports}" >
<fileset dir="${classes}">
<include name="**/Test*.class" />
</fileset>
</batchtest>
<formatter type="xml" />
<classpath refid="project.classpath" />
</junit>
<junitreport todir="${test.reports}">
<fileset dir="${test.reports}">
<include name="TEST-*.xml" />
</fileset>
<report todir="${test.reports}" />
</junitreport>
</target>
The test classes are in the build-directory together with the application classes, although they are in some subfolders according to their packages.
测试类与应用程序类一起位于构建目录中，尽管它们根据其包位于一些子文件夹中。
Maybe this is important too: At first Ant complained that JUnit wasn't in its classpath, but since I put it there (with the eclipse configuration editor) it complains about JUnit being in its classpath twice.
也许这也很重要：起初 Ant 抱怨 JUnit 不在它的类路径中，但是自从我把它放在那里（使用 eclipse 配置编辑器）它两次抱怨 JUnit 在它的类路径中。
WARNING: multiple versions of ant detected in path for junit
[junit] jar:file:C:/Users/as df/Documents/eclipse/plugins/org.apache.ant_1.7.1.v20090120-1145/lib/ant.jar!/org/apache/tools/ant/Project.class
[junit] and jar:file:/C:/Users/as%20df/Documents/eclipse/plugins/org.apache.ant_1.7.1.v20090120-1145/lib/ant.jar!/org/apache/tools/ant/Project.class
I've tried specifying each and every subdirectory, each and every class file, I've tried filesets and filelists, nothing seems to work.
我试过指定每个子目录、每个类文件，我试过文件集和文件列表，但似乎没有任何效果。
Thanks for your help, I've been sitting for hours on this thing now...
谢谢你的帮助，我已经在这件事上坐了几个小时了......

I had the same problem 'multiple versions of ant detected in path for junit'. The problem went away when I renamed by Eclipse_Home directory and removed special characters from it. The path had '[1]' in it which was causing the problem.
我有同样的问题“在junit的路径中检测到多个版本的蚂蚁”。当我通过 Eclipse_Home 目录重命名并从中删除特殊字符时，问题就消失了。路径中有“[1]”，这导致了问题。

I was getting this only when using the 'fork=true' option to the junit task. It was happening because my ANT_HOME had '..' in it (e.g. '/3rdparth/jboss/jboss-5/../tools'). Once I reduced that path, the 'multiple versions of ant' warning went away.
我只有在对 junit 任务使用 'fork=true' 选项时才得到这个。这是因为我的 ANT_HOME 中有“..”（例如“/3rdparth/jboss/jboss-5/../tools”）。一旦我减少了这条路径，“蚂蚁的多个版本”警告就消失了。

This Ant build.xml works fine for me. Check out the properties to see if the directory structure matches yours; adjust as needed.
这个 Ant build.xml 对我来说很好用。检查属性以查看目录结构是否与您的匹配；根据需要进行调整。
