Right way to use -make:transitive ?

[IttayD]

Hello,

I've read that the way to use scalac's -make:transitive is to add the
following to the plugin's configuration:
<arg>-make:transitive</arg>
<arg>-dependencyfile</arg>
<arg>$
{project.build.directory}/.scala_dependencies</arg>

However, wouldn't this cause any test compilation to override the
dependency file generated for the main compilation? If so, what is the
correct way?

Thank you,
Ittay

I don't use make:transitive (I used maven to make full build and eclipse for incremental).

Thnaks for reporting the issue, I'll try to provide a shorcut in the next version of the plugin (by defining default dependencyfile) to avoid the actual solution : create 2 executions :
