Gradle传递依赖不起作用？

Question

所以我在这里有一个项目，它有以下build.gradle：

// PLUGINS

plugins {
  id 'java' // or 'groovy' Must be explicitly applied
  id 'com.github.johnrengelman.shadow' version '1.2.2'
}

apply plugin: 'application'
apply plugin: 'java'

// REPOSITORIES & DEPENDENCIES

repositories {
    mavenCentral()
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'joda-time:joda-time:2.9'
    compile 'com.miglayout:miglayout-swing:5.0'
    compile 'com.dorkbox:SystemTray:1.9'
    compile 'com.dorkbox:SystemTray-Dorkbox-Util:1.9'
    compile 'net.java.dev.jna:jna:4.2.1'
    compile 'org.slf4j:slf4j-simple:1.7.5'
    compile 'commons-cli:commons-cli:1.3.1'
}

// SETTING THE MAIN CLASS

mainClassName = "com.github.tgharib.Program"

jar {
    manifest {
        attributes 'Main-Class': 'com.github.tgharib.Program'
    }
}

目前，遵循这些构建指令编译应用程序就好了。 但是，对于com.dorkbox:SystemTray库，我必须包含SystemTray的传递依赖： net.java.dev.jna:jna org.slf4j:slf4j-simple和org.slf4j:slf4j-simple 。 如果我理解正确，Gradle默认会自动包含传递依赖，但是如果我删除compile 'net.java.dev.jna:jna:4.2.1'行，我的程序仍然编译但是无法运行（因为JNA是运行时依赖项）。

我花了大约3个小时试图解决它但我无法解决它。 一个SO用户建议清除缓存，因为它解决了他的问题，但清除缓存并没有解决问题。 我还了解了gradle dependencies命令。 这是输出：

正如您所看到的，SystemTray确实包含JNA作为依赖项，但如果我在主项目中删除JNA依赖项，则无法运行。

Answer 1

它最终成为上游pom文件的一个问题。 他们将依赖项从编译时依赖项转换为运行时依赖项并修复了它。
