Ant 新手,JUnit 的 ClassNotFoundException [英] New to Ant, ClassNotFoundException with JUnit
问题描述
我已经为此挠头一段时间了(谷歌搜索了一堆,浏览了其他相关的 SO 帖子,但无济于事).我有一个由两个文件组成的 Java 程序,Logic
和 Tests
.Tests
包含大约一百个 JUnit 测试,我通过调用 javac *.java
和 java org.junit 获得了 100% 的成功率.runner.JUnitCore 测试
.但是,当我使用简单的 ant -verbose test
运行我的 build.xml
时(为了遵循输出,因为我对这一切都不熟悉),我得到以下内容输出:
I've been scratching my head over this for a while now (Googled a bunch, looked through other related SO posts to no avail). I have a Java program comprised of two files, Logic
and Tests
. Tests
contains about a hundred JUnit tests, and I've gotten 100% success rate with said tests by calling javac *.java
followed by java org.junit.runner.JUnitCore Tests
. However when I run my build.xml
with a simple ant -verbose test
(in order to follow the output since I'm new to all this), I get the following output:
[junit] Testsuite: Tests
[junit] Tests run: 1, Failures: 0, Errors: 1, Time elapsed: 0 sec
[junit]
[junit] Null Test: Caused an ERROR
[junit] Tests
[junit] java.lang.ClassNotFoundException: Tests
[junit] at java.lang.ClassLoader.loadClass(ClassLoader.java:247)
[junit] at java.lang.Class.forName0(Native Method)
[junit] at java.lang.Class.forName(Class.java:247)

[junit] Test Tests FAILED
BUILD SUCCESSFUL
我的build.xml
如下:
<project name="ETL_Automation" default="test" basedir=".">
<path id="classpath.base">
</path>
<path id="classpath.test">
<pathelement location="${basedir}/mysql-connector-java-5.1.18-bin.jar" />
<pathelement location="${basedir}/junit-4.10.jar"/>
<path refid="classpath.base" />
</path>
<target name="compile">
<javac srcdir="${basedir}">
<classpath refid="classpath.test"/>
</javac>
</target>
<target name="test" depends="compile">
<junit fork="no">
<classpath refid="classpath.test" />
<formatter type="brief" usefile="false" />
<batchtest>
<fileset dir="${basedir}/" includes="Tests.class" />
</batchtest>
</junit>
</target>
<target name="clean" depends="test">
<delete>
<fileset dir="${basedir}" includes="*.class"/>
</delete>
</target>
目录结构非常简单.Tests.java
、Logic.java
、junit-4.10.jar
、mysql-connector-java-5.1.18-bin.jar
、build.xml
和引用的 .properties
文件都在同一个文件夹中.Java 代码引用了外部文件,但这些文件与此特定问题无关.我不知道类路径是否可能是导致此问题的原因(因为我非常确信我目前拥有的方法不起作用).
The directory structure is pretty straightforward. Tests.java
, Logic.java
, junit-4.10.jar
, mysql-connector-java-5.1.18-bin.jar
, build.xml
, and a referenced .properties
file are all in the same folder. The java code references external files but those are unrelated to this particular issue. I don't know if the classpath could be the cause of this issue (as I'm pretty convinced what I currently have doesn't work).
谢谢!
推荐答案
您需要将带有 Tests.class
的目录添加到 classpath.tests
类路径(这是您设置中的 ${basedir}
)
You will need to add the directory with the Tests.class
to the classpath.tests
classpath (which is ${basedir}
in your setup)
试试:
<path id="classpath.test">
<pathelement location="${basedir}/mysql-connector-java-5.1.18-bin.jar" />
<pathelement location="${basedir}/junit-4.10.jar"/>
<pathelement location="${basedir}" />
<path refid="classpath.base" />
</path>
