While using NullAway, we get this error.. any clues

[nagkumar]

Changed

options.errorprone.disableWarningsInGeneratedCode.set(true)
    if (!name.lowercase(Locale.getDefault()).contains("test")) {
	configure<ErrorProneOptions> {
	    check("NullAway", CheckSeverity.ERROR)
	    option("NullAway:AnnotatedPackages", "com.tejasoft")
	}
    }

to this

tasks.withType {
options.errorprone.disableWarningsInGeneratedCode.set(true)
if (!name.lowercase(Locale.getDefault()).contains("test"))
{
options.errorprone {
check("NullAway", CheckSeverity.ERROR)
option("NullAway:AnnotatedPackages", "com.tejasoft")
}
}
}

It is working now.. documents this way are to be corrected as they give the first snippet..

Any case author pl. confirm the proposed gradle configuration is correct..

You might want to use my net.ltgt.nullaway plugin to make it even easier to configure, but indeed changing configure<ErrorProneOptions> to options.errorprone is the right thing to do, as the ErrorProneOptions extension is added to the options object, not the JavaCompile task itself.

Further improvements:

• use withType<JavaCompile>().configureEach {: https://docs.gradle.org/current/userguide/task_configuration_avoidance.html
• directly configure the compileJava task rather than excluding the test tasks

With all those applied, you'd have something like:

nullaway {
  annotatedPackages.add("com.tejasoft")
}
tasks {
  withType<JavaCompile>().configureEach {
    options.errorprone.disableWarningsInGeneratedCode.set(true)
  }
  compileJava {
    options.errorprone.nullaway.error()
  }
}

(fwiw, I prefer nesting everything: options.errorprone { disableWarningsInGeneratedCode.set(true) }, but YMMV)
