[BUG] Simple POJO with AllArgsConstructor fails to compile

[boonware]

I have created a simple POJO like so (methods left out):

@AllArgsConstructor
public class MyClass {

    private final String key;

    private final String value;

}

I receive the following error when compiling

error: constructor MyClass in class MyClass cannot be applied to given types; new MyClass("foo", "bar")); ^ required: no arguments found: String,String reason: actual and formal argument lists differ in length

If I remove the annotation and create a simple constructor then it compiles fine.

Details:

• Lombok 1.18.12
• JDK 8
• Gradle 6.5.1
• Same error observed using Gradle on command line or running from IDE (IntelliJ).

Sounds like lombok isn't getting a chance to generate that constructor.

Do you have lombok configured as an annotation processor?

Met the same issue with gradle, but the same code works with maven.

Fixed inspired by https://projectlombok.org/setup/gradle.

Added the following to build.gradle and it works like a charm!

...
dependencies {
...
    compileOnly 'org.projectlombok:lombok:1.18.22'
    annotationProcessor 'org.projectlombok:lombok:1.18.22'
    testCompileOnly 'org.projectlombok:lombok:1.18.22'
    testAnnotationProcessor 'org.projectlombok:lombok:1.18.22'
....
}
...
