如何克服`文件名或扩展名太长`错误与Windows中的Gradle

Question

在Jhipster中使用以下配置生成的默认应用程序中，在Windows中运行gradlew gatlingRun失败并显示以下堆栈跟踪

 {
  "generator-jhipster": {
    "baseName": "jhipster",
    "packageName": "com.mycompany.myapp",
    "packageFolder": "com/mycompany/myapp",
    "authenticationType": "session",
    "hibernateCache": "hazelcast",
    "clusteredHttpSession": "no",
    "websocket": "spring-websocket",
    "databaseType": "sql",
    "devDatabaseType": "h2Memory",
    "prodDatabaseType": "mysql",
    "searchEngine": "no",
    "useCompass": false,
    "buildTool": "gradle",
    "frontendBuilder": "grunt",
    "javaVersion": "8",
    "rememberMeKey": "93ff732a10ab7d74fc26c1518ee79338de1cd149"
  }
}

在gradle论坛上看到了一个类似的bug，但是那个看起来很旧而且固定了https://issues.gradle.org/browse/GRADLE-2167

我尝试减少我的类路径，但没有用，仍然是同样的错误。 该死的窗户！ gradle添加的类路径太长，所有这些都生成了缓存文件夹名称。 看到这篇文章，所以想知道是否有一些配置可以在窗口上使用gradle https://discuss.gradle.org/t/filename-too-long-in-windows/9222任何gradle专家来抢救plz

以下是此问题的工作修复，感谢@atomfrede Manifest jar需要命名为gatlingBooter.jar，Gatling版本需要为2.1.6

task manifestJar(dependsOn:'compileTestScala',type: Jar) {
    dependsOn configurations.testCompile
    archiveName 'gatlingBooter.jar'
    doFirst {
        manifest {
            // uri is just needed for Windows-compatibility
            attributes 'Class-Path': configurations.testCompile.files.collect{ project.uri(it) }.join(' ')
        }
    }
}

task gatlingRun(dependsOn:'manifestJar', type: JavaExec) {

     group = "gatling"

     standardInput = System.in

     final def sourceSet = sourceSets.test
     File configFile = file('src/test/gatling/conf/gatling.conf')

     def String gatlingDataFolder = "$project.rootDir.absolutePath/src/test/gatling/data"
     def String gatlingReportsFolder = "$project.buildDir.absolutePath/reports/gatling"
     def String gatlingBodiesFolder = "$project.rootDir.absolutePath/src/test/gatling/bodies"
     def String gatlingSimulationsFolder = "$project.rootDir.absolutePath/src/test/gatling/simulations"

    classpath sourceSet.output + files(manifestJar.archivePath) + files("src/test/gatling/conf")
     main = "io.gatling.app.Gatling"

     environment GATLING_HOME:''

     args '-df', gatlingDataFolder
     args '-rf', gatlingReportsFolder
     args '-bdf', gatlingBodiesFolder
     args "-sf", gatlingSimulationsFolder

 }

Gatling 2.2（尚未发布，没有ETA）将通过将类路径作为仅清单jar传递来解决Windows命令行长度限制，请参阅https://github.com/gatling/gatling/issues/2732 。

在发布之前，您可以使用Sonatype上发布的 2.2.0-SNAPSHOT。 Ot抛弃Windows并使用Linux或OSX。
