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.

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:

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.

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
