“The filename or extension is too long error” usin

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

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)
     }
 }

Answer 2

Recently I have the same problem and this plugin solved it! https://github.com/viswaramamoorthy/gradle-util-plugins

Answer 3

boot module do this:

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 4

One of the reasons I found the command line was becoming too long was because of some kind of unique id used by gradle in file path.

for example gradle uses jar file el-impl-2.1.2-b03.jar from

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

while the same file in maven is at

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

That is 90 chars vs 150 chars. So if we put the same artifacts in maven, overall size of command line becomes small.

Use these steps to install the jars that can be found in central maven repo to your local maven repo. Then use mavenLocal() as repo in you gradle build file.

Step 1) Create a dependency report

gradlew dependencies > tmp.txt

Step 2) Create a batch file to downloads the dependencies (I use cygwin, if you don't have then use another Linux machine to exeute this command and create install.To.Maven.bat file (note: dos2unix may need to be replaced by 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

Step 3) Run the bat file to download and install artifacts into local maven repo.

install.To.Maven.bat

Answer 5

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 {

 }
