Question

我有一个简单的gradle文件，我可以从中创建一个jar文件当我运行jar文件但是我得到并且错误：'线程中的异常“main”java.lang.NoClassDefFoundError：scala / Predef $'

build.gradle看起来像这样：

apply plugin: 'scala'
apply plugin: 'distribution'

def mainClass = "com.domain.Hello"

distributions {
    custom {}
}

repositories {
    mavenCentral()
}

dependencies {
    compile group: 'org.scala-lang', name: 'scala-library', version: '2.11.4'
}

jar {
    manifest {
        attributes 'Main-Class': mainClass
    }
}

task run(type: JavaExec, description: "Runs the project") {
    main = mainClass
    classpath sourceSets.main.runtimeClasspath
    classpath configurations.runtime
}

Answer 1

您需要包含＆＃39;＆＃39; scala-compile＆＃39;在＆＃39; scala-library＆＃39;

旁边打包

Answer 2

运行jar时，需要在类路径中包含scala-library，如此

scala -cp [scala library jar] [project jar]
