Question

我有Jhipster框架中的以下gradle脚本。它用于运行Gatling测试，由于Windows上的命令行限制，我尝试使用仅清单jar方法。有关此问题的详细讨论可在此处找到Jhipster issue 但是下面的脚本似乎正确地生成了Manifest jar，但是JavaExec无法找到主类，一些指针就可以了。错误的控制台日志也在下面

我已在gradle论坛here上发布此内容，但到目前为止没有运气

申请插件：'scala'

sourceSets {
    test {
        scala {
            srcDirs = ['src/test/gatling/simulations']
            output.classesDir = 'target/test-classes'
        }
    }
}
task manifestJar(dependsOn:'compileTestScala',type: Jar) {
    dependsOn configurations.runtime
    classifier 'pathing'
    doFirst {
        manifest {
            // uri is just needed for Windows-compatibility
            attributes 'Class-Path': configurations.runtime.files.collect{ project.uri(it) }.join(' ')
        }
    }
}
task gatlingRun(dependsOn:'manifestJar', type: JavaExec) {
    //dependsOn configurations.runtime
    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 + sourceSet.runtimeClasspath + files("src/test/gatling/conf")
    classpath sourceSet.output + files(manifestJar.archivePath) + files("src/test/gatling/conf")
    //classpath = files(pathingJar.archivePath)
    main = "io.gatling.app.Gatling"

    environment GATLING_HOME:''

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

}

编辑：您的清单jar包含错误的类路径。尝试使用testCompile个文件：

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(' ')
       }
   }
}

OLD：

如果清单jar只能运行java -jar @Deepu，我们可以尝试以下方法：

task runJar(dependsOn:jar) << {
  javaexec { main="-jar"; args jar.archivePath } 
}

至少它看起来不错。将在周末尝试测试。
