【问题描述】：

我正在创建一个 Grails 项目，我需要集成 Neo4j 和 Mongodb，对于 neo4j，我使用 SDN(Spring Data Neo4j)，对于 MongoDb，我们使用 Grails Plugin

This is our Dependencies and Plugins 
 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'
        //  compile 'org.grails:grails-datastore-gorm:3.1.2.RELEASE'
        //  compile 'org.grails:grails-datastore-core:3.1.2.RELEASE'
        //  test 'org.grails:grails-datastore-simple:3.1.2.RELEASE'
            //compile 'org.grails:grails-datastore-gorm:3.1.0.RELEASE'
            //compile 'org.grails:grails-datastore-core:3.1.0.RELEASE'
        //  test 'org.grails:grails-datastore-simple:3.1.0.RELEASE'
          //  test "org.grails:grails-datastore-test-support:1.0-grails-2.4"
            compile 'org.springframework.data:spring-data-neo4j-rest:3.2.0.RELEASE'
            compile 'org.springframework.data:spring-data-commons:1.9.0.RELEASE'
            //compile 'javax.validation:validation-api:1.1.0.Final'



        

        plugins 
            // plugins for the build system only
            build ":tomcat:7.0.54"
            compile ":mongodb:3.0.2"
            // 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"
        

现在当我们运行我们的项目时，它会显示一个错误

我们尝试了很多依赖，他们在 BuildConfig.groovy 中添加了注释，但是每次都会出现异常，请建议我们

【参考方案1】：

问题已解决。缺少依赖 用这个 `

改变你的 BuildConfig.grrovy

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

        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://repository.jboss.com/maven2/"
        mavenRepo 'http://m2.neo4j.org/content/repositories/releases/'
    

    dependencies 
        compile 'org.springframework.data:spring-data-mongodb:1.6.0.RELEASE'

        compile 'javax.validation:validation-api:1.1.0.Final'



    

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

    //  compile ":neo4j:2.0.0-M02"

【讨论】：

我收到一个关于 config found neo4j 的错误...有什么想法吗？
