buildTimeLog=false has no effect

[VladislavTitov]

I set buildTimeLog to false at every place where I apply plugin, f.e.

// app module
apply plugin: "com.archinamon.aspectj-ext"

aspectj {
    buildTimeLog = false
    includeAspectsFromJar 'aspects_provider'
}

or/and

// aspects_provider module
apply plugin: 'com.archinamon.aspectj-provides'

aspectj {
    buildTimeLog false
}

But build output looks like
