Where/how to get the MSVC dlls Java 1.8.0_144 wants?

问题

I'm experimenting with building my application with Java 1.8.0_144 to workaround an issue that apparently started after that. I run this command to build:

gradle jfxNative -Dorg.gradle.java.home="c:\Program Files\Java\jdk1.8.0_144"

and it stops with this error:

Execution failed for task ':jfxNative'.
> Not found MSVC dlls

Where and how do I get these MSVC dlls?

The full output looks like this:

c:\...\>gradle jfxNative -Dorg.gradle.java.home="c:\Program Files\Java\jdk1.8.0_144"

> Task :jfxNative 
The jar lib\lombok-1.16.18.jar has a main class lombok.launch.Main that does not match the declared main tech.dashman.dashman.ConfiguratorApp
The jar lib\jna-4.5.0.jar has a main class com.sun.jna.Native that does not match the declared main tech.dashman.dashman.ConfiguratorApp
The jar lib\javassist-3.22.0-CR2.jar has a main class javassist.CtClass that does not match the declared main tech.dashman.dashman.ConfiguratorApp

My current list of dependencies look like this:

dependencies {
    compile "tech.dashman:dashmancommon:1.0.0-SNAPSHOT"
    compile "org.projectlombok:lombok:1.16.18"
    compile "org.springframework:spring-web:5.0.2.RELEASE"
    compile "org.springframework.retry:spring-retry:1.2.2.RELEASE"
    compile "com.fasterxml.jackson.core:jackson-databind:2.9.3"
    compile "org.kordamp.ikonli:ikonli-javafx:2.1.0"
    compile "org.kordamp.ikonli:ikonli-fontawesome5-pack:2.1.1"
    compile "net.harawata:appdirs:1.0.1"
    compile "io.sentry:sentry:1.6.4"
    compile "org.javassist:javassist:3.22.0-CR2"
    testCompile "junit:junit:4.12"
}

I tried adding

compile "net.java.dev.jna:jna-platform:4.5.1"

to that list but I'm still getting the same error when trying to build the installer.

Adding it to my buildscript dependencies did not change the error either:

buildscript {
    repositories {
        mavenCentral()
        jcenter()
    }
    dependencies {
        classpath "de.dynamicfiles.projects.gradle.plugins:javafx-gradle-plugin:8.8.2"
        classpath "com.github.ben-manes:gradle-versions-plugin:0.17.0"
        classpath "de.dynamicfiles.projects.javafx.bundler:custom-file-extension-windows-bundler:1.0.2-SNAPSHOT"
        classpath "net.java.dev.jna:jna-platform:4.5.1"
    }
}

You need to install Microsoft Visual C++ redistribute package

In any case this is better solution to build JNA from source code using Visual studio 17, which is using universal CRT so that you don't need to ask your user to install it, since it is already installed by Windows update service.
