Question

我正在创建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插件

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，当我们运行项目时，它显示错误

我们尝试了许多依赖关系，他们在BuildConfig.groovy中发表评论，但我们每次都会得到例外，请建议我们

解决了问题。缺少依赖性用这个`

更改你的BuildConfig.groovy

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://download.java.net/maven/2/"
        //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 'org.springframework.data:spring-data-neo4j-rest:3.2.0.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"
        // plugins for the compile step

        compile ":scaffolding:2.1.2"
        compile ':cache:1.1.7'
        compile ":asset-pipeline:1.8.11"
        compile ":mongodb:3.0.2"
        runtime ":jquery:1.11.1"

    }
}
