Question

我最近更新了我的代码，当我尝试在命令行中使用 g bootRun 运行我们的应用程序时，我遇到了这个错误。

以下是gradle中的任务：

  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：

我有类似的问题，在我的情况下这很好用：

 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)
     }
 }

Answer 2

如果使用JetBrains Intellij Idea，则可以通过一个简单的设置解决它。转到运行/调试配置，然后将“缩短命令行”设置为“ JAR manifest”。不过，您应该为运行的每个配置设置它。

最近我遇到了同样的问题，这个插件解决了它！ https://github.com/viswaramamoorthy/gradle-util-plugins

Answer 4

启动模块执行此操作：

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)
        }
    }
}

Answer 5

只需将此插件 ManifestClasspath 添加到build.gradle文件中，然后指定清单类路径即可。 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 {

 }

Answer 6

我发现命令行太长的原因之一是因为gradle在文件路径中使用了某种独特的ID。

例如gradle使用

中的jar文件 el-impl-2.1.2-b03.jar

C:\Users\bob\.gradle\caches\modules-2\files-2.1\org.glassfish.web\el-impl\2.1.2-b03\6bab1211b6e6b191fdbf06067bd05d2f75a62ac0\el-impl-2.1.2-b03.jar

maven中的相同文件位于

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。因此，如果将相同的工件放入Maven，则命令行的整体大小将变小。

使用以下步骤将可以在中央Maven存储库中找到的jar安装到本地Maven存储库中。然后在gradle构建文件中使用mavenLocal（）作为仓库。

第1步）创建依赖项报告

gradlew dependencies > tmp.txt

第2步）创建一个批处理文件以下载依赖项（我使用cygwin，如果没有，请使用另一台Linux计算机执行此命令并创建install.To.Maven.bat文件（注意： dos2unix 可能需要替换为 fromdos ）

cat tmp.txt | tr ' ' '\n' | grep ':' | grep -e org -e com | sort -u  | xargs -n 1 -I fullname echo call mvn  dependency:get -Dartifact=fullname | dos2unix > install.To.Maven.bat

步骤3）运行bat文件以下载工件并将其安装到本地Maven存储库中。

install.To.Maven.bat

Answer 7

我有一个在Windows 8.1而非Windows 10上运行的Grails 3项目。answer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"

我也经常遇到这个问题。有时只需使用 IntelliJ Edit 配置缩短命令行即可解决上述评论中提到的问题。

如果上述方法不起作用，那么只需删除项目构建目录中的jar文件即可。

“文件名或扩展名太长错误”使用gradle
