> When the compiler executable path and fork properties are set, and also the compiler executable file does not exist, a CompilationFailureException is thrown with a message: "Compilation failure". The plugin should be able to check whether the compiler executable is a valid file, and print a message if it does not exist (e.g. {{"Path to compiler executable " + path + " is invalid. File not found."}})
> Here is an example of the maven compiler properties that can cause the error to occur:
> {code}
> <properties>
>   <maven.compiler.executable>/invalid/path/to/bin/javac</maven.compiler.executable>
>   <maven.compiler.fork>true</maven.compiler.fork>
> </properties>
> {code}
