Description
CLI with JDK 13
Class using String::indent method (introduced in Java 12)
CLI throws "No such field byte coder found in org.utbot.engine.overrides.strings.UtString"
To Reproduce
Steps to reproduce the behavior:
- Define JDK-13 as primary (Path, JAVA_HOME)
- Download one of the latest CLI from master
- For simplicity in the folder where utbot-cli*.jar is located :
Create ExampleString.java using String::indent method (introduced in Java 12)
public class ExampleString {
public void stringNewMethod() {
var text = "Hello!\nThis is String used with indent method.";
text = text.indent(-3);
System.out.println(text);
text = text.indent(-5);
System.out.println(text);
}
}
- Compile your files with JDK-13
javac -version
javac ExampleString.class
- Run utbot-cli to generate tests for it, like that:
java -jar utbot-cli-2022.7.jar generate --source ExampleString.java --classpath "D:\Current\Java" -o ExampleStringTest.java ExampleString
Expected behavior
Tests are supposed to be generated.
Actual behavior
There is the following output in console:
var adn String::indent nethod is used (12), compiled and executed with JDK-13
