我最近更新了代码，当我试图在命令行中使用g bootRun运行应用程序时，遇到了这个错误

堆栈跟踪：

这是gradle的任务：

  bootRun {
    if (project.hasProperty('args')) {
        args project.args.split('\\s+')
    }
  }

我们已经尝试减少项目的目录路径，但我们正在寻找另一种解决方案

这是我们项目的当前目录路径：

D:\Work\FBXX

我也有类似的问题，在我的情况下，这很好：

 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)
     }
 }

---

最近我有同样的问题，这个插件解决了它！ 引导模块执行以下操作：

if (OperatingSystem.current().isWindows()) {
    task classpathJar(type: Jar) {
        dependsOn configurations.runtime
        appendix = 'classpath'

        doFirst {
            manifest {
                attributes 'Class-Path': configurations.runtime.files.collect {
                    it.toURI().toURL().toString().replaceFirst(/file:\/+/, '/').replaceAll(' ', '%20')
                }.join(' ')
            }
        }
    }

    bootRun {
        dependsOn classpathJar
        doFirst {
            classpath = files("$buildDir/classes/java/main", "$buildDir/resources/main", classpathJar.archivePath)
        }
    }
}

只需在build.gradle文件中添加这个插件ManifestClasspath，并指定ManifestClasspath。 ManifestClasspath插件为JavaExec任务的类路径中的jar文件创建一个清单jar，并使用清单jar设置类路径

plugins {
    id 'org.springframework.boot' version '2.1.4.RELEASE'
    id 'java'
    id "com.github.ManifestClasspath" version "0.1.0-RELEASE"       
}

apply plugin: 'io.spring.dependency-management'
apply plugin: 'application'
mainClassName = 'com.example.demo.Application'
dependencies {

 }

我发现命令行变得太长的原因之一是gradle在文件路径中使用了某种唯一的id

例如，gradle使用jar文件el-impl-2.1.2-b03.jarfrom

C:\Users\bob\.gradle\caches\modules-2\files-2.1\org.glassfish.web\el-impl\2.1.2-b03\6bab121b6e6b191fdbf067bd05d2f75a62ac0\el-impl-2.1.2-b03.jar

而maven中的同一文件位于

C:\Users\bob\.m2\repository\org\glassfish\web\el-impl\2.1.2-b03\el-impl-2.1.2-b03.jar

这是90个字符对150个字符。所以，如果我们在maven中放置相同的工件，命令行的总体大小就会变小

使用以下步骤将可以在central maven repo中找到的JAR安装到本地maven repo。然后在gradle构建文件中使用mavenLocal（）作为repo

步骤1）创建依赖项报告

gradlew dependencies > tmp.txt

步骤2）创建一个批处理文件以下载依赖项（我使用cygwin，如果您没有，则使用另一台Linux计算机来执行此命令并创建install.to.Maven.bat文件（注意：dos2unix可能需要被fromdos替换）

步骤3） 运行bat文件将工件下载并安装到本地maven repo中

install.To.Maven.bat

如果您使用JetBrains Intellij Idea，您可以通过一个简单的设置来解决它。转到运行/调试配置并将Shorten命令行设置为“jarmanifest”。不过，您应该为运行的每个配置设置它

---

我有一个Grails 3项目在Windows 8.1上工作，但在Windows 10中没有。这帮助了我：

buildscript {
    repositories {
        maven { url "https://plugins.gradle.org/m2/" }
    }
    dependencies {
        classpath "gradle.plugin.com.github.viswaramamoorthy:gradle-util-plugins:0.1.0-RELEASE"
    }
}

apply plugin: "com.github.ManifestClasspath"

---

我也经常面对这个问题。有时，使用IntelliJ编辑配置缩短命令行就可以解决上述评论中提到的问题

---

如果上述方法不起作用，那么只需删除项目的build目录中的jar文件，它就会起作用。

你读过吗？看这里：你应该提供

build.gradle

文件！没有它，我们只能猜测！您是否使用了类似于

classpath=files（$buildDir/classes/main）的东西

？如果是这样，用

sourceset.main.compileClasspath

替换它。根据我的经验，前者连接所有

.class

路径，并形成一个很长的字符串，用作

java-classpath

命令的参数，因此会导致

文件名或扩展名太长

错误。一旦我更正检查

classpath=files的类路径（sourceset.main.output.files，pathingJar.archivePath）

这对我来说是错误的。我使用的是gradle 4.10.3。在gradle 4.x中，运行时配置被弃用。我将“runtime”替换为“runtimeClasspath”它成功了。谢谢，它对我起了作用，解决了我们过去几天遇到的问题！只需在build.gradle文件中添加以下内容对我起了作用：plugins{id“com.github.ManifestClasspath”version“0.1.0-RELEASE”}你的屏幕截图是针对Spring Boot应用程序的。这个问题是关于通过gradle运行某些东西的。你的回答似乎与这个问题无关。

buildscript {
    repositories {
        maven { url "https://plugins.gradle.org/m2/" }
    }
    dependencies {
        classpath "gradle.plugin.com.github.viswaramamoorthy:gradle-util-plugins:0.1.0-RELEASE"
    }
}

apply plugin: "com.github.ManifestClasspath"
