Question

我的应用程序是springboot gradle应用程序。我的部分应用程序涉及使用gradle的遗留gwt编译。它工作正常但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。以下代码的任何建议更改都可以解决此问题吗？

    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',
                    '-style', 'DETAILED',
                    '-localWorkers', '2',
                    '-compileReport',
                    '-gen', generatedDir,
                    '-extra', extraDir,
                    '-draftCompile' // Speeds up compile with 25%
            ]
    maxHeapSize = '1024M'


}

war.dependsOn compileGwt
war {
    from compileGwt.buildDir
}

下面是更新的带有pathingJar的build.gradle，当我运行compileGwt时，它会出错：无法找到或加载主类com.google.gwt.dev.Compiler

请参阅https://github.com/steffenschaefer/gwt-gradle-plugin/commit/087a94377fbd83cab938ffffe51ce8fab871be35，它对gwt-gradle-plugin应用了具有相同问题的修复程序。

而不是设置classpath，你应该可以做类似下面的事情

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

Answer 2

我修复了此gradle插件的类似问题：https://github.com/viswaramamoorthy/gradle-util-plugins

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

Answer 3

我根据fix for long classpath

的信息解决了此问题

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(' ')
  }
}

}

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'
}

}

我正在尝试运行标准的alon java程序。更改以下运行配置可解决我的问题

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