@UtilityClass - compilation error when using IMPORT STATIC

[islisava]

Compilation fails when I try to use import static for @UtilityClass method Here is example.

@UtilityClass
public class TodayUtils { 
    public LocalDateTime getTodayStartDay() {
        return LocalDate.now().atStartOfDay();
    }
}

import static packagename.TodayUtils.getTodayStartDay;

getTodayStartDay();

Can't reproduce. What error do you get? What Lombok version?

I had the same problem. In Eclipse everything worked fine. But if i built with maven directly lombok completely (as if it was never executed, not even the other lombok annotations) as soon as I imported static from UtilityClasses. The only error given was something like

[ERROR] /D:/REDACTED/models/Dataset.java:[78,70] cannot find symbol
[ERROR]   symbol:   method getDirectory()
[ERROR]   location: variable files of type REDACTED.DatasetFiles

The same missing symbol error repeated for each and every lombok generated method (e.g. getters and setters). As soon as I removed the static import everything worked fine again. I could reproduce the same problem with gradle+javac.

ps: Lombok 1.16.18, Java 1.8.0_131

Same is here.

OS: Windows 10 10.0
Lombok: 1.16.10

java version "1.8.0_141"
Java(TM) SE Runtime Environment (build 1.8.0_141-b15)
Java HotSpot(TM) 64-Bit Server VM (build 25.141-b15, mixed mode)

Always true with Lombok 1.16.20.

I have seen that this problem occurs if and only if :

• the code is compiled with Maven,
• the member is not declared static in the utility class,
• the member is statically imported in the other classes.

So, as a workaround, you can explicitly declare your members static in the utility class, as follow:

@UtilityClass
public class TodayUtils { 
    public static LocalDateTime getTodayStartDay() {
        return LocalDate.now().atStartOfDay();
    }
}

Proceeding that way, you will be able to use static imports, as in : import static packagename.TodayUtils.getTodayStartDay;

However, in this case, the only benefit of using @UtilityClass is the generation of the constructor which avoids the instantiation of the class :-(

Got same issue when building with gradle 4.7 and Lombok 1.16.20

[SergiusSidorov]

Same issue with lombok 1.18.0

This is a duplicate of many, many bug reports. However, lombok cannot fix this.

For those who are still facing the issue, change your import with using star. It solved my problem.

import static packagename.TodayUtils.getTodayStartDay; -> import static packagename.TodayUtils.*;

[banan314]

Same issue with 1.18.30, using star static import works
