no autocompletions or hints for referenced libraries.

[veksha]

Hi.
my OS is Windows 11. my editor is CudaText.

i get no autocompletions or hover hints for referenced libraries like for example - jackson.
e.g. lsp server cannot complete "JsonFactory" or "factory.createGenerator"

please help. what am i doing wrong?
file compiles without error.
i am not using maven/gradle. just simple file test.java and jackson-core-2.5.4.jar in the same folder.

settings:

{
    "java.project.ReferencedLibraries": {
        "include": ["jackson-core-2.5.4.jar"]
    }
}

test.java file:

import com.fasterxml.jackson.core.JsonFactory;
import com.fasterxml.jackson.core.JsonGenerator;
import com.fasterxml.jackson.core.io.SerializedString;
import com.fasterxml.jackson.core.util.DefaultPrettyPrinter;

import java.io.StringWriter;

public class test {
    public static void main(String[] args) {
        try {
            JsonFactory factory = new JsonFactory();
            StringWriter writer = new StringWriter();
            JsonGenerator generator = factory.createGenerator(writer);

            DefaultPrettyPrinter prettyPrinter = new DefaultPrettyPrinter();
            generator.setPrettyPrinter(prettyPrinter);

            generator.writeStartObject();
            generator.writeStringField("name", "Yura");
            generator.writeNumberField("age", 30);
            generator.writeEndObject();
            generator.close();

            System.out.println("Generated JSON: " + writer.toString());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

@veksha You can try the following

• create the lib directory
• move jackson-core-2.5.4.jar to the lib directory

thank you for answer. i tried - no change. :(

[snjeza]

Could you try to clean the workspace?

• Open the command palette (F1)
• select Java: Clean the Java Language Server Workspace
• select Restart and delete from the confirmation prompt

@snjeza i have CudaText and its lsp plugin has no support for code actions yet (i assume this is code action).
but i can manually delete any files just tell me where to look. thanks.
