If you want to get real fancy, you could make it into a combinator template grader, and give fewer marks if students submit code that generates warnings :-) But that's much harder. They could be question types like Java_program_allow_warnings, Java_class_allow_warnings etc. Read Also: Solved java uses or overrides a deprecated api. Recompile with -Xlint: unchecked for details in Java. Once you've got it working the way you want, you could make it into a new question type (or several types, adding appropriate extra Java code for 'write-a-function', 'write-a-class', 'write-a-program' questions as appropriate). In this post, I will be sharing how to fix unchecked or unsafe operations. That should, if I understand the Java compiler properly (which I don't) give you only genuine syntax errors rather than warnings. You could filter the stderr output to remove lines beginning with 'Note:' and print the rest to stdout. The relevant line here is "return_code = subprocess.call()": change that to a more-generic n (see documentation here) in which you capture the stdout and stderr output. To prevent that you'd have to change the script to capture the actual compiler output. But you'd still have the compiler warnings present in your got column, so the student would still fail the tests. class file after the compile phase and proceed to run the code if it's present, rather than abort if the compiler gives a non-zero return code. One option might be to check for the presence of a. Now it's over to you to decide exactly how you want the compile-and-run process to work in the presence of compiler warnings. That will lock the question into Java only and the language-select dropdown will disappear. Under Advanced Customisation, set the Ace language to Java rather than a comma-separated list of options. Customise it, and pull out all the non-Java-relevant code. Īs a starting point, to get a feel for what's possible, create a new write-a-program question of type 'multilanguage'. However, your situation may be different, so. PathProviderPlugin.java uses unchecked or. the code ArrayList foo new ArrayList () triggers that exception because javac is looking for ArrayList foo new ArrayListIt's usually asking you to be more explicit about types, in one way or another. Note: Recompile with -Xlint:unchecked for details. Note: Recompile with -Xlint:unchecked for details. The 'unchecked or unsafe operations' warning was added when java added Generics, if I remember correctly. Note: Some input files use unchecked or unsafe operations. firebaseanalytics-2.0.2+1androidsrcmainjavaioflutterpluginsfirebaseanalytics. 3 comments Closed FirebaseAnalyticsPlugin.java uses unchecked or unsafe operations.I wonder whether warnings like this (another example is the use of deprecated code) could be captured another way, as the current approach prevents tests from running that could actually be run? PathProviderPlugin.java uses unchecked or unsafe operations. Note: Recompile with -Xlint:unchecked for details. It could be given in the preloaded code, but that would require some more teaching.Ĭurrently CodeRunner reports this as a syntax errorīut actually this does not prevent the student's code from compiling and it's not really a syntax error, just an unsafe practice. It also doesn't work for a single class if the student must add an import (as the annotation isn't legal before an import). It is possible to suppress these messages programmatically, and sometimes this could be hidden in a template so that students don't have to know about this feature: if you want a student to submit more than one class in the same answer box, altering the template no longer works. firebaseauth-3.7.0androidsrcmainjavaioflutterpluginsfirebaseauthFlutterFirebaseAuthPlugin.java uses unchecked or unsafe operations. It used to be possible to suppress warnings like this at the compiler level by passing a flag like -Xlint:none or -nowarn, but as far as I can see this no longer works. Note: recompile with -xlint:unchecked for details" "Note: uses unchecked or unsafe operations. What happens is that when students use raw types the Java compiler generates a message like this: I'm raising the same question here because I think it is a more general issue. In gradle project, You can added this compile parameter in the following way: gradle.Another user posted a question here about this If you are using Maven, configure this in the maven-compiler-plugin -Xlint:uncheckedįor IntelliJ 13.1, go to File -> Settings -> Project Settings -> Compiler -> Java Compiler, and on the right-hand side, for Additional command line parameters enter "-Xlint:unchecked". Or if you are using Ant modify your javac target Specify it on the command line for javac: How do I recompile with -Xlint:unchecked? If I understand what you mean, for 6 it should 10 : 6 is not 1 : step 1. I'm getting a message when I compile my code: Note: H:\Project2\MyGui2.java uses unchecked or unsafe operations.
