在 Windows 上安装了最新版本的 grails 2.4.2(java 1.7)，创建了一个新项目。运行应用程序时，它无法解析依赖项。我不支持代理。在堆栈跟踪下方:

Required Grails build dependencies were not found. This is normally due to internet connectivity issues (such as a misconfigured proxy) or missing repositories in grails-app/conf/BuildConfig.groovy. Please verify your configuration to continue.

我的构建配置:

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 = 1.7
grails.project.source.level = 1.7
//grails.project.war.file = "target/${appName}-${appVersion}.war"
grails.project.plugins.dir="./plugins"

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 true // 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

        grailsPlugins()
        grailsHome()
        mavenLocal()
        grailsCentral()
        mavenCentral()
        // uncomment these (or add new ones) to enable remote dependency resolution from public Maven repositories
        mavenRepo "http://repository.codehaus.org"
        mavenRepo "http://download.java.net/maven/2/"
        mavenRepo "http://repository.jboss.com/maven2/"
    }

    dependencies {
        // specify dependencies here under either 'build', 'compile', 'runtime', 'test' or 'provided' scopes e.g.
        // runtime 'mysql:mysql-connector-java:5.1.29'
        runtime 'org.postgresql:postgresql:9.3-1101-jdbc41'
        test "org.grails:grails-datastore-test-support:1.0-grails-2.4"
    }

    plugins {
        // plugins for the build system only
        build ":tomcat:7.0.54"

        // plugins for the compile step
        compile ":scaffolding:2.1.2"
        compile ':cache:1.1.7'
        compile ":asset-pipeline:1.8.11"

        // plugins needed at runtime but not for compilation
        runtime ":hibernate4:4.3.5.4" // or ":hibernate:3.6.10.16"
        runtime ":database-migration:1.4.0"
        runtime ":jquery:1.11.1"

        // Uncomment these to enable additional asset-pipeline capabilities
        //compile ":sass-asset-pipeline:1.7.4"
        //compile ":less-asset-pipeline:1.7.0"
        //compile ":coffee-asset-pipeline:1.7.0"
        //compile ":handlebars-asset-pipeline:1.3.0.3"
    }
}

最佳答案

将它添加到你的 BuildConfig.groovy，如果它是 gradle

repositories {
    inherits true // Whether to inherit repository definitions from plugins
    grailsPlugins()
    grailsHome()
    grailsCentral()
    mavenCentral()

    // uncomment these to enable remote dependency resolution from public Maven repositories
    //mavenCentral()
    //mavenLocal()
    //mavenRepo "http://snapshots.repository.codehaus.org"
    //mavenRepo "http://repository.codehaus.org"
    //mavenRepo "http://download.java.net/maven/2/"
    //mavenRepo "http://repository.jboss.com/maven2/"
}

如果是maven则在pom.xml中跟随

<project ...>
<repositories>
    <repository>
      <id>central</id>
      <url>http://central.maven.org/maven2/</url>
    </repository>
 </repositories>
</project>
