JUnit NoClassDefFoundError 与 JAR 文件

发布于 2024-11-07 08:47:53 字数 1833 浏览 4 评论 0原文

我开发了一个 Android 应用程序，现在正在为其创建单元测试。我创建了第二个项目（后缀为“.test”作为项目名称）并选择原始项目作为目标。

我的原始项目包含一些外部 JAR 文件。

如果不在我的测试项目的构建路径中引用这些 JAR 文件，我就无法访问测试中的所有方法。例如，我收到此错误：

The type com.j256.ormlite.android.apptools.OrmLiteBaseService cannot be resolved. It is indirectly referenced from required .class files

测试确实可以正常工作（当不访问这些方法时）。

如果我在测试项目的构建路径中包含所需的 JAR 文件，则会收到此错误：

如何解决 NoClassDefFoundError？我真的很困惑，因为它引用了我的项目中的一个类，并且当外部 JAR 文件不包含在构建路径中时它可以工作。

我在 OSX 上使用 Eclipse，如果这有任何影响的话。

原文

I have developed an Android application which I am now creating unit tests for.
I have created a second project (suffixed with ".test" as the projectname) and selected the original project as the target.

My original project includes a few external JAR files.

I cannot access all methods from my tests without referencing these JAR files in my test project's build path as well.
As an example, I get this error:

The type com.j256.ormlite.android.apptools.OrmLiteBaseService cannot be resolved. It is indirectly referenced from required .class files

Tests do work correctly though (when not accessing those methods).

If I include the required JAR files in the test project's build path, I get this error however:

05-16 15:59:03.732: INFO/TestRunner(1222): java.lang.NoClassDefFoundError: sw6.visualschedule.persistence.DatabaseHelper

05-16 15:59:03.732: INFO/TestRunner(1222):     at junit.framework.TestCase.run(TestCase.java:118)
05-16 15:59:03.732: INFO/TestRunner(1222):     at android.test.AndroidTestRunner.runTest(AndroidTestRunner.java:169)
05-16 15:59:03.732: INFO/TestRunner(1222):     at android.test.AndroidTestRunner.runTest(AndroidTestRunner.java:154)
05-16 15:59:03.732: INFO/TestRunner(1222):     at android.test.InstrumentationTestRunner.onStart(InstrumentationTestRunner.java:520)
05-16 15:59:03.732: INFO/TestRunner(1222):     at android.app.Instrumentation$InstrumentationThread.run(Instrumentation.java:1447)

How can I resolve the NoClassDefFoundError?
I am really confused since it refers to a class inside my project, and it works when the external JAR file isn't included in the build path.

Im using Eclipse on OSX, if that has any influence.
