Question

此hello world project运行正常，但hello_api-latest.jar文件在哪里？（无论客户端实际上并不“需要”JAR，它仍然应该下载。）

JAR位于类路径中：

thufir@mordor:~/NetBeansProjects/hello_client$ 
thufir@mordor:~/NetBeansProjects/hello_client$ gradle clean build;java -jar build/libs/hello_client.jar
:clean
:compileJava
:processResources UP-TO-DATE
:classes
:jar
:startScripts
:distTar
:distZip
:assemble
:compileTestJava UP-TO-DATE
:processTestResources UP-TO-DATE
:testClasses UP-TO-DATE
:test UP-TO-DATE
:check UP-TO-DATE
:build

构建文件：

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

sourceCompatibility = '1.8'
[compileJava, compileTestJava]*.options*.encoding = 'UTF-8'
if (!hasProperty('mainClass')) {
    ext.mainClass = 'Main'
}

mainClassName = 'net.bounceme.mordor.Main'

repositories {
    mavenCentral()
    maven { url "https://jitpack.io" }

}

dependencies {
    testCompile group: 'junit', name: 'junit', version: '4.10'
    compile 'com.github.THUFIR:hello_api:latest'

}



jar {
    manifest {
        attributes ('Main-Class': 'net.bounceme.mordor.Main',
            "Class-Path": configurations.compile.collect { it.getName() }.join(' '))
    }
}

值得注意的是，在Netbeans中没有显示jitpack依赖：

log末尾的构建工件似乎表明找到了JAR hello_api-latest.jar：

与任何外部依赖项一样，它会下载到gradle缓存中。默认位置为~/.gradle

jitpack下载构建工件到哪里去了？
