Re: [tycho-user] Conventions/procedures for using properties file resources in Tycho-built applications?
|
In our Project (Eclipse based RCP) with many Eclipse Plug-ins we do have a Eclipse Fragment Project for each Plug-in. The packaging type of the Fragment Projects are "eclipse-test-plugin" and contain all the tests for a specific plugin, including basic unit tests and more complex tests.
With that approach you do also have separated the test code from the other code like it is done in pure maven using the different folders.
You might want to take a look at the tycho-demo projects "itp01" [1] which contains one Plug-in Project and a Test-Fragment for it.

Really? Ok. I guess I'll try to move it back to that structure, then.
I wrote a "true" unit test that doesn't use Tycho (Surefire handles this), so I had put that in "src/test/java", and I also discovered that I had to tell the tycho-compiler-plugin to exclude that.
What exactly is the purpose of the "source.." property? If I put my "deployable" source files in "src" and created something like "srctestjava" and put my true unit test there (setting the "testSourceDirectory" to that), would that be ok? Does the "source.."
property only refer to Java source that the tycho-compiler-plugin will be handling?
