Code completion for annotation parameters like @Mapping is not working

[UnclePi979]

As mentioned in issue https://github.com/mapstruct/mapstruct-idea/issues/182, I have similar issues.

I have even disabled lombok plugin I have even disabled all downloaded plugins. Even using mapstruct-examples still doesn't work.

Problems encountered follows.

Effective features:

1. Jump to the specified field
2. Highlight Unmapped property: xxx
3. Auto-implement mapper interface

Broken features:

1. Annotation auto-completion, like @Mapping @Mappings, etc.

Configurations

We would really like to help but were not able to reproduce this yet.

Do you have JUnit in your project? Could you try to check if the code completion of JUnit works? To narrow down the problem if it is related to the MapStruct plugin or IntelliJ itself.

import java.util.Arrays;
import java.util.List;

import org.junit.jupiter.params.ParameterizedTest;
import org.junit.jupiter.params.provider.MethodSource;

public class DemoTest {

    public static List<String> someNames() {
        return Arrays.asList( "Alex", "Peter" );
    }

    @ParameterizedTest
    @MethodSource("someNames") // code-completion should work here
    void testSomeNames(String name) {
        // no-op
    }

}

Thank you for your reply. I used the example you provided to test the code completion, and it indeed does not work. The issue seems to be with Intellij, not mapstruct-idea.

Oh my goodness, it turns out to be because the shortcut key for switching input methods in Mac OS conflicts with the shortcut key for code completion. lol 😂😂

Thanks again to @thunderhook, I think this issue can be closed.
