When I use Scanners or try to get a user input, I get the message:
FAILURE: Build failed with an exception.
What went wrong:

When I just use a system.out.println();
It goes through successfully.
Here is my code:
/**
*
* #author boaz5
*/
import java.io.IOException;
import java.util.Scanner;
public class Main {
/**
* #param args the command line arguments
*/
public static void main(String[] args) throws IOException {
System.out.println("What is your name?");
Scanner name = new Scanner(System.in);
String nameString = name.next();
System.out.println("Hi," + nameString);
}
}
I'm not sure what I'm doing wrong. I am a complete newbie and this is one of my first Java projects. Thanks!
Not much to go on here, but I can give a couple suggestions to get started:
1.) Update your Gradle plug-in. The compilation issue may not be code related, but instead a problem with the tooling.
2.) If above fails replace the IOException with Exception and see if we get any further output.
Let us know
you should review your environment, I did copy your code and work for me.

Hi,Alvaro
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
There is no problem in your code. The code is running without any error.
I think you added the processor as a compile dependency. You should add it as 'provided'.

Resources should be closed
Connections, streams, files, and other classes that implement the Closeable interface or its
super-interface, AutoCloseable, needs to be closed after use. Further, that close call must be
made in a finally block otherwise an exception could keep the call from being made. Preferably,
when class implements AutoCloseable, resource should be created using "try-with-resources"
pattern and will be closed automatically.
Failure to properly close resources will result in a resource leak which could bring first the
application and then perhaps the box the application is on to their knees.
etc ...

I am building a gradle java project using sublime, instead of an IDE like eclipse. I have notice when I run the build task, I do not get any warnings about unused imports.
Is there a compiler option in java that can turn on my strict warnings? If so, how do I enable that in my build.gradle?
Thanks.
Warning on unused imports is not something the Java compiler currently handles: https://docs.oracle.com/en/java/javase/14/docs/specs/man/javac.html#examples-of-using--xlint-keys
You can use an external code style tool to take care of that for you. For example, with Spotless
plugins {
`java`
id("com.diffplug.gradle.spotless") version "4.0.0"
}
spotless {
java {
eclipse()
removeUnusedImports()
trimTrailingWhitespace()
endWithNewline()
}
}
and the following Java source with unused List import:
import java.util.List;
public class Example {
public static void main(String[] args) {
System.out.println("hello");
}
}
when I try to build the project, I will immediately get an error:
> Task :build FAILED
