classPathFile should not use exposed in configuration

[szpak]

The Gradle plugin itself doesn't provide a direct way to specify a classpath passed to PIT - it is based on the project configuration. Due to an oversight classPathFile has been exposed directly in the plugin configuration. It should be enough to have a useClassPathFile boolean configuration switch to pass a classpath to PIT using an automatically generated file instead of a classpath command line parameter.

Available in 1.2.2 - useClasspathFile = true has to be added to the plugin configuration.

You should document this on the README.md file, as it took me 2 days to scour the Internet to find this plugin option 😄

I'm glad you finally found it :).

However, in the README file there is:

 - useClasspathFile - enables passing additional classpath as a file content
 (useful for Windows users with lots of classpath elements, disabled by default - since 1.2.2)

Nevertheless, feel free to provide a PR with improvements :).

You think I would read the entire documentation before announcing my ignorance to the whole world 😢
Thanks for a great plugin!
