CreateProcess error=206，运行gwtCompile时文件名或扩展名太长

Question

我的应用是springboot gradle应用。 我的应用程序的一部分涉及遗留 gwt 使用 gradle 编译。它工作正常但是今天当我运行下面的 gradle 任务时，它显示 CreateProcess error=206，文件名或扩展名太长。 可能出了什么问题？ 因为它以前工作过。 对以下代码有任何建议的更改以解决此问题吗？

    task compileGwt(dependsOn: classes, type: JavaExec) {
    //ext.buildDir = "${project.buildDir}/resources/main/static"
    ext.buildDir = "${project.rootDir}/src/main/webapp"
    //ext.buildDir = "${project.buildDir}"
    ext.extraDir = "${project.buildDir}/extra"
    ext.generatedDir = "${project.buildDir}/generated"

    inputs.source sourceSets.main.java.srcDirs
    inputs.dir sourceSets.main.output.resourcesDir
    outputs.dir buildDir

    // Workaround for incremental build (GRADLE-1483)
    outputs.upToDateSpec = new org.gradle.api.specs.AndSpec()

    doFirst {
        file(buildDir).mkdirs()
        //classpath.each { println it.name}
    }

    main = 'com.google.gwt.dev.Compiler'

    classpath {
        [
                sourceSets.main.java.srcDirs,           // Java source
                sourceSets.main.output.resourcesDir,    // Generated resources
                sourceSets.main.output.classesDir,      // Generated classes
                sourceSets.main.compileClasspath,       // Deps
        ]
    }

    args =
            [
                    'com.company.application.UI', // Your GWT module
                    '-war', buildDir,
                    '-logLevel', 'INFO',

                    '-compileReport',
                    '-gen', generatedDir,
                    '-extra', extraDir,
                    '-draftCompile' // Speeds up compile with 25%
            ]
    maxHeapSize = '1024M'


}

war.dependsOn compileGwt
war {
    from compileGwt.buildDir
}

下面是带有 pathingJar 的更新后的 build.gradle，当我运行 compileGwt 时，它给出错误提示：Could not find or load main class com.google.gwt.dev.Compiler

我用这个 gradle 插件修复了一个类似的问题： https : //github.com/viswaramamoorthy/gradle-util-plugins

buildscript {
    dependencies {
        classpath "com.github.viswaramamoorthy:gradle-util-plugins:0.1.0-RELEASE"
    }
}
...
apply plugin: 'ManifestClasspath'

Answer 2

请参阅https://github.com/steffenschaefer/gwt-gradle-plugin/commit/087a94377fbd83cab938ffffe51ce8fab871be35 ，它对具有相同问题的 gwt-gradle-plugin 进行了修复。

您应该可以执行以下操作，而不是设置类路径

            if (System.getProperty("os.name").toLowerCase().contains("windows")) {
                javaExecSpec.environment("CLASSPATH", classpath.getAsPath());
            }

Answer 3

我根据修复长类路径的信息修复了这个问题

1. 创建以下任务：

    task pathingJar(type: Jar) { dependsOn configurations.runtime appendix = 'pathing' doFirst { manifest { attributes "Class-Path": configurations.runtime.files.collect { it.toURL().toString().replaceFirst(/file:\\/+/, '/') }.join(' ') } }

   }

2. 在 bootRun 中使用此任务

   task bootRunDev(type: org.springframework.boot.gradle.tasks.run.BootRun, dependsOn: 'build') { dependsOn pathingJar group = 'application' jvmArgs = [ "-agentlib:jdwp=transport=dt_socket,server=y,address=8000,suspend=n" ] doFirst() { main = bootJar.mainClassName classpath = files(sourceSets.main.output.files, pathingJar.archivePath) systemProperty 'spring.profiles.active', 'development' }

   }

Answer 4

我试图运行独立的 Java 程序。 在运行配置中更改以下内容修复了我的问题

Answer 5

这是在 gradle4.10 中工作的@GLK pathingJar解决方案的简化版本：

task pathingJar(type: Jar) {
    dependsOn configurations.runtimeClasspath
    appendix = 'pathing'

    doFirst {
        manifest {
            Set<File> classPathJars = configurations.runtimeClasspath.files
            attributes "Class-Path": classPathJars.collect {it.toURI().toURL().toString().replaceFirst("file:/", '/')}.join(" ")
        }
    }
}

bootRun {
    dependsOn pathingJar
    doFirst {
        classpath = files(sourceSets.main.output.files, pathingJar.archivePath)
    }
}

我的sourceSets.main.output.files （在 groovy 版本中）解析为： [<projectRoot>\build\classes\java\main, <projectRoot>\build\classes\groovy\main, <projectRoot>\build\resources\main]
