No Code completions anymore?

还没有人认领这个 Issue。

I'm hesitant to post this as issues like this tend to be a misconfig somewhere...

I'm no longer getting any code completions at all from MapStruct. I initially thought this was because we used records almost exclusively everywhere, but now I tried to create a simple POJO and that offers no code completions for `@Mapping` either.

Eclipse 2023-09, MapStruct Tools 0.1.0.201701192129. The error log seems clear. Enabling or disabling "Enable non-blocking completions" makes no difference.

Example code:

```java
@Mapper
public interface AhaMapper {
@Mapping(target = "name", source = "name2")
Aha fromDto2(Aha2 ahaaa);
}

public static class Aha {
private final String name;

public Aha(String name) {
this.name = name;
}

public String getName() { return name; }
}

public static class Aha2 {
private final String name2;

public Aha2(String name2) {
this.name2 = name2;
}

public String getName2() { return name2; }
}
```

未指定任何 repository 文件、测试或入口点。在 Eclipse 2023-09 中使用 MapStruct Tools 0.1.0.201701192129 重现该示例，检查报告的错误日志，并比较启用和禁用非阻塞补全时的补全行为。当 @Mapping 代码补全能够用于所提供的 mapper 示例时，即视为完成。
