Deprecated features of Gradle

[danwallach]

Currently this:

Deprecated Gradle features were used in this build, making it incompatible with Gradle 6.0.
Use '--warning-mode all' to show the individual deprecation warnings.
See https://docs.gradle.org/5.4/userguide/command_line_interface.html#sec:command_line_warnings

The problem seems to be the way we're calling project.javaexec:

gradle.buildFinished { ignoredResult ->
    project.javaexec {
        classpath = configurations.ricechecks
        main = "edu.rice.autograder.AutoGraderKt"
        args = [ "--project", gradeProject,
                 "--config", gradeConfig,
                 "grade" ]
    }
}

Possible solution: finalizedBy:

Or, we just wait for an improvement to the GoogleJavaFormat plugin so we don't have to wait until the build is finished.

Or we could just capture stdout, like we do with the Java compiler.
