/** Compiles a single `module-info.java` source file with the default java compiler (
* the one that is defined for the project). Before the module-info is compiled, all the
* class files from `scopeFilter` are copied into the `target` directory of the current project.
* This is because we want the `module-info.java` to be an *Uber module-info* that is defined for
* multiple sbt projects, like `runtime` and `runtime-with-instruments`, so before the `module-info.java`
* is passed to the compiler, we need to copy all the classes from the sbt projects into a single directory
* so that the compiler has an illusion that all these projects are in fact a single project.
*
* Note that sbt is not able to correctly handle `module-info.java` files when
* compilation order is defined to mixed order.
*
* Compilation of `module-info.java` is skipped iff none of all the classes from all the dependencies
* changed and if the `module-info.java` itself have not changed.
*
* @param copyDepsFilter The filter of scopes of the projects from which the class files are first
* copied into the `target` directory before `module-info.java` is compiled.
* @param modulePath IDs of dependencies that should be put on the module path. The modules
* put into `modulePath` are filtered away from class-path, so that module-path
* and class-path passed to the `javac` are exclusive.
* @param modulePathExtra More directories that should be added on `--module-path`. This parameter is of
* type [[File]], because this is how inter project dependencies are gathered.
*
