Using generated code in unit tests with maven clean build?

I have a maven project using the JAXWS plugin to generate some WSDL based code using wsimport. If I run mvn generate-sources, this code is generated.

In addition, I have JUnit unit tests that reference the generated classes.

According to docs, when installed by default, tests must be run after generation sources in order for them to work. However, if I run the assembly on a clean workspace in eclipse, I get NoClassDefFound for one of the generated classes. If you then run the installation a second time, it will work.

It was a bit strange, so I got out of the eclipse and went back to the basics of the command line. If I do this sequence, I will get a NoClassDefFound error:

  • mvn clean
  • mvn install

However, if I do the following, it works without error:

  • mvn clean
  • mvn clean install

How can it be? I would think that mvn clean install would be equivalent to mvn clean + mvn install?

In addition, when these are errors, I see at the output of the console that the code generation phase is actually executed before it runs the tests. A class exists, but the class loader does not seem to see it.

I do not see any other errors in the console output. Just a few warnings about specifying version numbers of the plugin and source files are encoded in cp1252. Nothing interesting.
