Could not find method lombok() for arguments

Question

Just wanted to include the lombok plugin with my gradle build but get the error message from the title. My build.gradle looks like this:

...
plugins {
    id 'net.ltgt.apt' version '0.10'
}
ext {
    lombok_version="1.16.18"
}
lombok {
    version = ${lombok_version}
    sha256 = ""
}
...
dependencies {
    ...    
    compileOnly "org.projectlombok:lombok:${lombok_version}"
    apt "org.projectlombok:lombok:${lombok_version}"
    ...
}

Source: https://projectlombok.org/setup/gradle

Any ideas what's wrong here? If I remove the lombok {...} part everything works fine.

Answer 1

According to the documentation you should use either

lombok {
    version = "1.16.18"
    sha256 = ""
}

or

dependencies {
    compileOnly 'org.projectlombok:lombok:1.16.18'
    apt "org.projectlombok:lombok:1.16.18"
}
