unit test not finding dependent class
Hi,
Here is the information about maven I use:
Apache Maven 2.2.0 (r788681; 2009-06-26 06:04:01-0700)
Java version: 1.6.0_17
Java home: /System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home
Default locale: en_US, platform encoding: MacRoman
OS name: "mac os x" version: "10.6.3" arch: "x86_64" Family: "mac"
I see strange unit test failure which was due to a dependent class in the
same package not being found:
java.lang.NoClassDefFoundError:
com/ciq/m2m/platform/mmp2/input/OtaUploadRecordReader
at
com.ciq.m2m.platform.mmp2.input.OtaUploadRecordReaderSingleFileTest.createRecordReader(OtaUploadRecordReaderSingleFileTest.java:18)
In Eclipse, I can successfully run the same unit test.
Can someone provide hint ?
Thanks

I ran into something similar yesterday (however, in that case it didn't work
with m2e either). The scm used was clearcase (dynamic view) which was likely
causing the problem (it had happened before apparently).
I don't know why, but after several "mvn clean install" and removing the
local repo at least once, I got it to work.
Are you using clearcase?

Seems like you've exhausted the capabilities of this list without
providing either more information or more ideally a sample project
that demonstrates the issue. Can you provide one?

Yu
Anders..Kalpak and Ron are correct ..changing the package name causes this problem
If you disagree.. post your code and pom.xml and settings.xml (and indicate which version of maven) so we can download and test your configuration
Are you using the shaded plugin ?

I abbreviated the company name for privacy.
That shouldn't be the cause.

The classes are not dynamically loaded.

The test runner will segregate the classes by providing a custom class loader for each test. All your classes will be added to this child class loader. So trying to load classes from System class loader will fail as the System class loader does not know about these classes.

Re: unit test not finding dependent class
Posted by Kalpak Gadre <ka...@gmail.com>.
Just in case.. Are you dynamically loading these classes from your code?
You can see these kind of errors in case you are dynamically loading
classes using System class loader instead of the immediate class loader.
The test runner will segregate the classes by providing a custom class
loader for each test. All your classes will be added to this child class
loader. So trying to load classes from System class loader will fail as
the System class loader does not know about these classes.

-rw-r--r-- 1 tyu staff 5691 May 16 08:58
target/classes/com/ciq/m2m/platform/mmp2/input/OtaUploadRecordReader.class
That test passes.
But the same problem appears for other tests:
arvindmac:m2m-platform tyu$ vi
target/surefire-reports/com.ciq.m2m.platform.mmp2.MeasureMergeReducerTest.txt
java.lang.NoClassDefFoundError: com/iq/m2m/platform/tester/MergePkgsTester
Although the class has been generated:

Re: unit test not finding dependent class
Posted by Anders Hammar <an...@hammar.net>.
Is OtaUploadRecordReader a class you've written and that's in the same Maven
project? If so, check that it is being compiled by checking that the .class
file exists under target/classes/
If it's not being compiled there's some error you need to fix in your
project.
