"The filename or extension is too long error" using gradle

Question

I have recently updated my code and when I tried to run our application using g bootRun in the command line, I encountered this error.

Stack Trace:

Here's the task in gradle:

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

We have tried reducing the directory path of our project but we're looking for another solution.

This is the current directory path of our project:

D:\Work\FBXX

Answer 1

Just add this plugin ManifestClasspath in your build.gradle file and specify the manifest classpath. ManifestClasspath plugin creates a manifest jar for jar files in the classpath of JavaExec task and sets the classpath with the manifest jar.

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 2

I had similar problem, in my situation this works fine:

 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)      }  }
