Gretty and inplaceMode

[alabotski]

I modify your test build.gradle file

plugins {
    id 'org.gretty' version '2.3.1'
    id 'com.devsoap.vaadin-flow' version '1.0.0.RC7'
}

repositories {
    vaadin.prereleases()
    vaadin.addons()
}

vaadin {
    productionMode false
    submitStatistics false

    version '13.0.0.alpha3'
    
    autoconfigure()
}

gretty {
    servletContainer = 'tomcat8'
    jacocoEnabled = false
    inplaceMode = 'hard'
}

dependencies {
    implementation vaadin.bom()
    implementation vaadin.platform()
}

So now, when I have such string inplaceMode = 'hard'
I can't download my own CSS styles.
