在网上看到一篇帖子(http://jira.codehaus.org/browse/GRAILS-6057),其中说类/ JAR需要添加到测试或运行类路径.问题：这是指定的？另外,我是否需要在’dependencies’部分下的Grails配置文件(BuildConfig.groovy)中指定依赖项？如何为罐子指定这些例如我在/ lib文件夹下的jar是’ant-1.6.5.jar’？

grails.project.class.dir = "target/classes"
grails.project.test.class.dir = "target/test-classes"
grails.project.test.reports.dir = "target/test-reports"
//grails.project.war.file = "target/${appName}-${appVersion}.war"
grails.project.dependency.resolution = {
// inherit Grails' default dependencies
inherits( "global" ) {
    // uncomment to disable ehcache
    // excludes 'ehcache'
}
log "warn" // log level of Ivy resolver,either 'error','warn','info','debug' or 'verbose'
repositories {        
    grailsPlugins()
    grailsHome()

    // uncomment the below to enable remote dependency resolution
    // from public Maven repositories
    mavenLocal()

    //mavenCentral()
    //mavenRepo "http://snapshots.repository.codehaus.org"
    //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 eg.

    runtime 'net.sf.json-lib:json-lib:2.3.jdk15'
}

}

解决方法

您可以指定一个平面目录和一个特定的jar文件


repositories { 
        grailsPlugins() 
        grailsHome() 
        grailsCentral() 

        // uncomment the below to enable remote dependency resolution 
        // from public Maven repositories 
        mavenLocal() 
        mavenCentral() 

        // Hardcoded path to the jar fiels
        flatDir name:'myRepo',dirs:'/${PATH}/lib' 

    } 
    dependencies { 
        // specify dependencies here under either 'build','test' or 'provided' scopes eg. 
        specify the jar file here
        compile 'org.neo4j:${YOUR_JAR_NAME}:1.4.1' 


    }
