【中文标题】gradle bootRun 执行失败

【问题描述】：

我正在尝试运行我的 springboot 应用程序...这一切都始于我将 eureka spring-cloud 插件添加到我的 gradle.build 文件中：

编译'org.springframework.cloud:spring-cloud-starter-eureka'

当我运行“gradle bootRun”时，我得到了这个错误：

原因：java.io.IOException：无法运行程序“C:\Program Files\Java\jdk1.8.0_91\bin\java.exe”。 CreateProcess 错误=206，文件名太长。

我的 build.gradle 是：

import java.text.SimpleDateFormat

    springBootVersion = '1.3.2.RELEASE'
    elasticSearchVersion = '2.2.0'
    groovyVersion = '2.4.5'

springBoot 
  executable = true

我把插件拿出来，它可以正确执行。

我知道这应该是 Windows 问题长路径，但我该如何给出解决方案？

感谢 tim_yates！我在这一行添加了简单的引号：it.toURL().toString().replaceFirst('/file:/+/', '/')

【参考方案1】：

tim_yates 是对的，谢谢！

我从链接中获取代码并将其粘贴到我的 build.gradle 文件的末尾，它就像一个 gem！

我添加的代码是：

task pathingJar(type: Jar) 
    dependsOn configurations.runtime
    appendix = 'pathing'

    doFirst 
        manifest 
            attributes "Class-Path": configurations.runtime.files.collect 
                it.toURL().toString().replaceFirst('/file:/+/', '/')
                .join(' ')
        
    


bootRun 
    dependsOn pathingJar
    doFirst 
        classpath = files("$buildDir/classes/main", "$buildDir/resources/main", pathingJar.archivePath)
    

注意：我在链接代码中添加了一些简单的引号 (') 以使其正常工作..
