我正在尝试在 Grails/Netbeans 中执行 tutorial 并最终安装了 Grails 2.2.4 版。我尝试创建一个域类，但出现了几个服务器访问错误：

任何想法如何解决这个问题？我看到的最接近的是link，但它有所不同，所以我不确定它是否对我有帮助。感谢您的帮助！

有人问 buildConfig.groovy 长什么样子：

grails.servlet.version = "3.0" // Change depending on target container compliance (2.5 or 3.0)
grails.project.class.dir = "target/classes"
grails.project.test.class.dir = "target/test-classes"
grails.project.test.reports.dir = "target/test-reports"
grails.project.work.dir = "target/work"
grails.project.target.level = 1.6
grails.project.source.level = 1.6
//grails.project.war.file = "target/${appName}-${appVersion}.war"

grails.project.fork = [
    // configure settings for compilation JVM, note that if you alter the Groovy version forked compilation is required
    //  compile: [maxMemory: 256, minMemory: 64, debug: false, maxPerm: 256, daemon:true],

    // configure settings for the test-app JVM, uses the daemon by default
    test: [maxMemory: 768, minMemory: 64, debug: false, maxPerm: 256, daemon:true],
    // configure settings for the run-app JVM
    run: [maxMemory: 768, minMemory: 64, debug: false, maxPerm: 256, forkReserve:false],
    // configure settings for the run-war JVM
    war: [maxMemory: 768, minMemory: 64, debug: false, maxPerm: 256, forkReserve:false],
    // configure settings for the Console UI JVM
    console: [maxMemory: 768, minMemory: 64, debug: false, maxPerm: 256]
]

grails.project.dependency.resolver = "maven" // or ivy
grails.project.dependency.resolution = {
    // inherit Grails' default dependencies
    inherits("global") {
        // specify dependency exclusions here; for example, uncomment this to disable ehcache:
        // excludes 'ehcache'
    }
    log "error" // log level of Ivy resolver, either 'error', 'warn', 'info', 'debug' or 'verbose'
    checksums true // Whether to verify checksums on resolve
    legacyResolve false // whether to do a secondary resolve on plugin installation, not advised and here for backwards compatibility

    repositories {
        inherits true // Whether to inherit repository definitions from plugins

    dependencies {
        // specify dependencies here under either 'build', 'compile', 'runtime', 'test' or 'provided' scopes e.g.

        // runtime 'org.postgresql:postgresql:9.3-1100-jdbc41'
    }

    plugins {
        // plugins for the build system only
        build ":tomcat:7.0.52.1"

        // plugins for the compile step
        compile ":scaffolding:2.0.2"
        compile ':cache:1.1.1'

        // plugins needed at runtime but not for compilation
        runtime ":hibernate:3.6.10.9" // or ":hibernate4:4.3.4"
        runtime ":database-migration:1.3.8"
        runtime ":jquery:1.11.0.2"
        runtime ":resources:1.2.7"
        // Uncomment these (or add new ones) to enable additional resources capabilities
        //runtime ":zipped-resources:1.0.1"
        //runtime ":cached-resources:1.1"
        //runtime ":yui-minify-resources:0.1.5"

        // An alternative to the default resources plugin is the asset-pipeline plugin
        //compile ":asset-pipeline:1.6.1"

        // Uncomment these to enable additional asset-pipeline capabilities
        //compile ":sass-asset-pipeline:1.5.5"

        //compile ":coffee-asset-pipeline:1.5.0"
        //compile ":handlebars-asset-pipeline:1.3.0.1"
    }
}

【问题讨论】：

你能把你BuildConfig.groovy的内容贴出来吗？
@Don-buildConfig.groovy 已添加到上面的原始问题中。
您的网络连接似乎有问题，您需要通过代理服务器连接吗？
另外，它不会解决您的问题，您的 BuildConfig.groovy 文件不适用于 Grails 2.2.4 版。它适用于 Grails 2.3.x。分叉执行是 2.3 中的一个新特性。有关详细信息，请参阅here。不过我同意唐的观点。看起来是互联网连接问题。
我想知道 2.3 是否出现了，因为我下载了 2.3，创建了 netbeans 项目，发现包中缺少东西的问题，然后下载了 2.2.4，没有意识到它基于 2.3 创建了东西包裹。我将研究互联网连接。有没有在netbeans中设置代理服务器的地方？使用 groovy/etc 进行 Web 开发对我来说是新的。

【解决方案1】：

看起来这是一个 netbeans 设置问题。我需要以不同于在 IE 中显示的方式配置代理。谢谢！
