java - 运行 junit 任务时 Bamboo Ant 任务失败

Question

在我当前的项目中，我正在使用 junit 测试。在我的本地电脑上运行我的 ant 文件会按预期生成我的测试报告，但是当 bamboo 尝试运行我的测试时，它会生成以下输出。

我的错误是什么？

SimplerTest.java

import static org.junit.Assert.*;

import org.junit.Test;

public class SimplerTest {


@Test
public void dummerTest()
{
    assertTrue(true);
}
}

本地输出:

Buildfile: C:\Users\jussi\git\kingdom-builder-repository\build.xml

compile-test:
[javac] Compiling 1 source file to C:\Users\jussi\git\kingdom-builder-repository\bin

junit:

服务器输出:

感谢 Ant 的详细输出。

看来您正在 Bamboo 服务器上运行 Ant 1.9.0。 Ant 错误跟踪器中存在一个已知问题(错误 54835 - Classpath use seems to be broken in junit ant task?)，该问题是由 SO 上类似问题的发帖人发起的:“Class not found with Ant, Ivy and JUnit - error in build.xml? ”:

BUILD FAILED
/home/andrew/project/guice/hg/build.xml:33: java.lang.NoClassDefFoundError: junit/framework/TestListener
        at java.lang.ClassLoader.defineClass1(Native Method)
        at java.lang.ClassLoader.defineClass(ClassLoader.java:791)

        at java.net.URLClassLoader$1.run(URLClassLoader.java:366)
        at java.net.URLClassLoader$1.run(URLClassLoader.java:355)
...

该问题没有明确/简短的答案，但错误报告有:

It looks like the class search is being delegated to the System's classloader rather than being handled by the Ant Classloader (the system Classloader has no knoweldge of JUnit since JUnit isn't on the core Ant Classpath, but is added to the JUnit task by Ivy). Given some JUnit classes must have already been loaded to have reached this point, the Ant Classloader can see the JUnit jars loaded by Ivy, but the Split Classloader seems to be delegating incorrectly when trying to load classes used by the JUnit Runner.

换句话说:Ant 的 JUnit 任务有错误，无法运行，我认为您受到了这个特定错误的影响。错误报告继续并列出了这些修复/解决方法:

• 等待 Ant 1.9.1(错误报告已标记为已修复，预计很快就会发布)
• 将 JUnit JAR 复制到 ANTLIB 目录并继续使用 Ant 1.9.0。如果您想混合使用 JUnit 版本，这不是很好，但如果您只使用 4.10 左右，它应该可以工作。
• 使用 Ant 1.8.4
