Maven , Junit ClassNotFound Exception
Hello everyone ,
using maven 1.0.2
and junit 3.8.1
machine MAC OSX
So i am building this project using maven and i have a unit test that
i'm trying
to get it to work in maven but so far no luck
my project.xml has this junit dependency defined and nothing else
<!-- Junit for my unit testing -->
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>3.8.1</version>
<type>jar</type>
<properties><war.bundle>false</war.bundle></properties>
</dependency>
as to the build part it goes as follows
<build>
<nagEmailAddress>krikor_krumlian@me.org</nagEmailAddress>
<sourceDirectory>src</sourceDirectory>
<unitTestSourceDirectory>src/test</unitTestSourceDirectory>
<!-- Unit test cases -->
<unitTest>
<includes>
<include>**/*Test*.java</include>
</includes>
</unitTest>
</build>
So now building my app using the command maven test:test
gives me the following
__ __
| \/ |__ _Apache__ ___
| |\/| / _` \ V / -_) ' \ ~ intelligent projects ~
|_| |_\__,_|\_/\___|_||_| v. 1.0.2
build:start:

Thank you martijn Dashorst
Figured out my mistake and what was happening , the problem was that in
my unit tests
I have specified the package name test , So maven was putting the
classes in in test-classes/test/Testxxx.class
and thus it was not finding it later when it needed to test. so when
you have testcases in the /test/ folder
dont' specify package name.
test:test:
[junit] Running KkTest
[junit] Tests run: 1, Failures: 0, Errors: 1, Time elapsed: 0 sec
[junit] Testsuite: KkTest
[junit] Tests run: 1, Failures: 0, Errors: 1, Time elapsed: 0 sec

[junit] Null Test: Caused an ERROR

[junit] at java.lang.Class.forName0(Native Method)
[junit] at java.lang.Class.forName(Class.java:141)
[junit]
So if you ever recieve this kind of error while trying to unit test ,
make sure package
names are correct.
things learned
Maven -X debug to check classpath and what not
Thank you all , hope you never do this mistake

Try the 'maven genapp' plugin, which will provide you with a Java
project which has all you need to answer your question(s).

Hello everyone
Has anyone been able to make junit tests work in maven ? If yes
can you show me the dependency you used maven version and
the <unitTest> stuff .
It seems so easy and should work but for some reason i have not been
able to .
thank you
